Esri vector basemaps updated

Recent updates to Esri Vector Basemaps deployed new map content from contributing cities and counties who supplied data through our Community Maps Program to enhance our maps. Contribute your organization’s local, authoritative content through this program.  Esri integrates your data with other providers and publishes the tile set as the ArcGIS Online vector basemap. Additionally, this release has one of the first rounds of contributions coming from the Esri Community Maps Editor. With the start of baseball spring training, there is a new Community Maps Challenge focused on compiling detailed content of the stadiums. Details available online.

Basemap localization

Czech, Finnish, Hebrew, and Swedish are the newest languages in our vector basemap localization styles. Currently we publish 17 languages, besides our global English map, in nine basemap styles each. The available languages:

 

The link on the language names takes you to a group page of web maps. To get localized language maps in your ArcGIS.com gallery, change your organization’s Region and Language in the General settings. Make sure Esri vector basemaps are set as the default gallery. This option is in the Map settings. More language updates and more languages are planned in future releases. Translations are expanding across more feature classes and to larger scales.

 

Do you want to convert one of your custom Esri vector basemaps into a map that displays a localized language? Our World_Basemap_v2 tile set includes the language data that allows you to do that. See the Esri Vector Basemap Reference Document (v2) for details on how to customize your map to expose translated labels. The reference document includes the list of layers this supports and the 2-digit language codes needed when editing json. Try starting with one of our existing localized map styles and apply your own cartographic styling.

 

The reference document also provides details on how to customize the vector basemap boundaries and names to display a preferred world view. Disputed boundaries can be removed or changed to non-disputed. Alternate names for select features can appear on the map by json code modifications (for example, The Gulf -or- Persian Gulf -or- Arabian Gulf). Note:  North Macedonia country name can be exposed by a JSON modification to your own map layer. It will be the default name on the Esri Vector Basemaps in our March update.

This example shows the Nova creative vector basemap style with Hebrew labels. You can achieve a similar result with any of the Esri creative styles or your own vector style built on the Esri Vector Basemaps. Make a copy of the tile layer in your own account using the ArcGIS Vector Tile Style Editor. Download the root.json style file from this new tile layer's item page. Select fields identified in the reference document are edited in Notepad++ changing _name to _name_he ("he" for Hebrew): "text-field" : "{_name_he}". Fonts also change to Arial Unicode (bold or regular) to display the appropriate glyphs, Finally, update the item's root.json style file.

Community:  a new creative style for vector basemaps

A new creative vector style is available for your basemap use. “Community” provides a customized world basemap that is uniquely symbolized. It is optimized for the display of special areas of interest (SAI) created and edited by Community Maps contributors. These special areas of interest features include landscaping polygons and sport ammenity lines. These are features such as grass, trees, rock, tennis courts, football and baseball lines, and more. This vector tile layer is built using the same data sources used for the World Topographic Map and other Esri basemaps. Cindy Prostak is the cartographer behind the design of Community, as well as many of our other creative styles including Charted Territory, Colored Pencil, Mid-Century, Modern Antique, Newspaper, and Nova.

 

Check out this Story Map which builds off both our Community Maps baseball stadium challenge and our new Community style vector basemap. It also presents a number of real-world running challenges for you to conquer!

Customize the look of your own vector basemaps

In addition to customizing the language or geopolitical view of your vector basemaps, you can also edit overall cartographic styling. Change the root.json code in a text editor and update your tile layer. Alternately, try the ArcGIS Vector Tile Style Editor (beta) app for a user-friendly experience to change your map’s look.  The Quick Editor function changes features en masse.  In contrast, the editor also has an Edit Layer Styles option for a deep dive into individual map specifications. Change style settings for text, sprites, lines, polygons, and point features with the editor app. Edit one of the Esri vector basemaps or use it to edit your own vector tile layer created through ArcGIS Pro.

GeoNet:  The Esri Community

Finally, ask questions, share updates, and browse the ArcGIS Living Atlas of the World product page.

Wayback provides access to each version of the World Imagery map published since 2014.  While designed to enable users to step backward through the World Imagery timeline, Wayback has recently taken a significant step forward.  Wayback is officially out of beta and now includes World Imagery metadata.

As of December 14, 2018, Wayback includes 89 versions of World Imagery, with metadata now available for each.

What is World Imagery Metadata?

Simply put, metadata is “data that provides information about other data”, or “data about data”. Accordingly, World Imagery metadata provides detailed information and metrics (data) about the input imagery sources (data) that comprise the World Imagery map.

Sometimes a visual inspection of the imagery is all a user needs to select one image source over another. In other cases, a user may need additional information about the individual images that have been compiled, measured, and blended together during the creation and curation of the World Imagery map. The individual images in the map may vary by capture date, available level of detail, and/or how the features (roads, buildings, etc.) are represented with respect to their true location on the ground. The metadata exposes this type of information to support more informed decision making.

It is worth noting that two distinct dates are now presented in Wayback, ‘map publication’ dates and ‘image capture’ dates. As before, Wayback layers have the map publication date embedded in the name. This is the date when a particular version of the World Imagery map was updated and published. The publication date applies collectively to all of the imagery included in a version of the map, but does not indicate the actual vintage of individual images within the map. The age of a particular image can now be determined with the capture date provided in the metadata popup window, displayed when a user points and clicks on a location in the map.

Discovery

The Wayback app was already a great tool for exploration and discovery of Wayback imagery. With the seamless integration of the metadata, we can easily access all of this additional information about the imagery. Try this: 1) Open the Wayback App 2) Click on the map. Voila, a great looking popup with detailed information about the imagery.

 

 

When executing the “export to web map” functionality, the selected image layers, AND the associated metadata layers, are saved to the custom web map.

 

 

Outside the app, all of the Wayback metadata is available as individual ArcGIS Online layer items for use in Online, Pro, and custom applications. Search ArcGIS Online from Pro or the Online Map Viewer.  Browse or search the Wayback Imagery group, where you can find each Wayback imagery item along with its associated Wayback metadata item.

 

More Information

For more information see the following:

This blog was originally posted on the esri.com ArcGIS blog site. For more Esri vector basemap blogs, see this page.

 

Esri Vector Basemaps were recently updated with new data, a new Ocean Reference style and made more localized languages available.

 

New content added to the Esri Vector Basemap tile set is available across all the styles of our vector tile layers. These updates include data from HERE as well as from our Community Maps Program contributors. The banner image of this blog shows voestalpine steel mill in Austria, a new addition of contributed data to the map. This industrial campus displays trees, parking lots, and other special areas pertinent to this site. Learn more about what data your campus or community can contribute to the ArcGIS.com platform. Visit this Living Atlas of the World page.

The Living Atlas is also a great place to find the Esri Vector Basemaps. Find the layers and maps directly from the Living Atlas website or search the Living Atlas through ArcGIS Online (left image below) or Pro (right). Narrow your search to vector maps, a sub-category of the basemaps category. Additionally, the Esri Vector Basemaps can be set as the default maps for your basemap gallery.

 

ArcGIS.com and Pro windows

 

Ocean reference vector layer

New additions to the suite of Esri Vector Basemap layers and maps are the World Ocean Reference vector layer and Ocean Basemap web map which utilitizes the vector layer. The new vector ocean reference layer has similar content and design as the existing raster ocean reference layer (boundaries and all labels). Because it is vector format, there is the ability to customize not only the content of the layer, but also the appearance of the display. This includes changing boundary line symbolization and font styles (face, color, size). This customization can be made through the editing of the root.json style file of your tile layer or through the ArcGIS Vector Tile Style Editor app.

Localization of vector basemaps

There are three additional languages available across the vector basemap styles. This brings our current total to twelve languages. Each language localized is available in nine different basemap styles. New are Arabic, Chinese (Hong Kong) and Chinese (Taiwan). These join previously released Modern ChineseFrenchGermanItalianJapanesePolishBrazilian PortugueseRussian, and Spanish. To make localized maps the default basemap, change the organization’s Region and Language in the General settings. Also, change the Map setting to display Esri vector basemaps as the default gallery. Each language above is linked to a group of web maps. Localized labels display primarily at small scales; however, we are expanding translations across more feature classes and at more scales. Additional languages will be deployed in future releases.

 

 

Customizing Esri Vector Basemaps

The Esri Tile Layer Style Editor (Beta) provides an easy way to customize vector basemaps. Experiment (& save!) different cartographic styles with this app. Start from an Esri vector basemap or one of your own vector tile layers. Two styling paths exist:

 

Quick Edit is only configured for Esri vector basemaps. This quick path sorts map features into six high-level categories. Apply random colors for cartographic inspiration, or apply a pre-defined color palette to each category.

 

Edit Layer Styles works with Esri vector maps and your own styles. It offers more control over each map feature’s spec. Countless options are available to customize your new vector map. Save your new style as a tile layer in your ArcGIS.com account and use the new style in your web maps and apps. This blog and space on GeoNet offers information about the Style Editor. This recent Esri Webinar showcased the Style Editor. Follow-up questions and answers are at this Living Atlas GeoNet page.

Did you know that you can create custom Arcade expressions to define your symbol sizes at the varying ArcGIS Online map scales? The Arcade code demonstrated here on Esri’s “Recent Hurricane Live Feed will show you how to automatically resize your symbols as you zoom in and out of your map.

 

Hurricanes!

Within the Living Atlas is a “Recent Hurricane” layer that features tropical cyclone (hurricanes, typhoons, cyclones) tracks and positions from the past year for the Atlantic, Pacific, and Indian Basins. Esri hosts this data from the National Hurricane Center (NHC) and Joint Typhoon Warning Center (JTWC).

 

For this example you will be copying these links:

1. Hurricane – Recent Observed Positions (point file) service is located: https://livefeeds.arcgis.com/arcgis/rest/services/LiveFeeds/Hurricane_Recent/MapServer/0

2. Spinning Blue Hurricane (PNG symbol) is located: https://arcgis-content.maps.arcgis.com/sharing/rest/content/items/f67790e2d65143f1af2edca3bab4c739/data

 

Monitoring agencies worldwide use varying wind speed criteria and terminology for tropical cyclone classifications. The NHC and JTWC use the Saffir-Simpson Wind Scale to classify storms in the Western Hemisphere. This ranking system places storms with different wind speed thresholds (one-minute maximum sustained wind speed) into the following three classes:

 

Major (Devastating/Catastrophic)
Category 5 Hurricane: > 137 knots | >157 mph | >252 kmh
Category 4 Hurricane: 113-136 knots | 130-156 mph | 209-251 kmh
Category 3 Hurricane: 96-112 knots | 111-129 mph | 178-208 kmh

 

Very/Extremely Dangerous
Category 2 Hurricane: 83-95 knots | 96-110 mph | 154-177 kmh
Category 1 Hurricane: 64-82 knots | 74-95 mph | 119-153 kmh

 

Related Classifications
Tropical Depression: <33 knots| <38 mph | <62 kmh
Tropical Storm: 34-63 knots | 39-73 mph |63-118 kmh

 

Symbology

There are standard symbols for hurricanes:

 

 

Standard symbols for Depression, Storm, and Hurricane.

 

 

Using the Saffir-Simpson Wind Scale classifications, Category 1-5 Hurricanes will be displayed with a hurricane symbol to differentiate them from Tropical Storms and Depressions.

 

As a cartographer I see some room for interpretation here. I decide to take the standard symbol and tweak it a bit, so it spins like a hurricane and add an eye. It needs life and vibrations like it is moving, but there also should be a nod to the original symbol.  This change makes a visual statement that could be immediately recognizable (abstractly it looks like a hurricane) to someone who is looking at the map and they may not need a legend to determine what the symbol is.

Classify the Hurricane Data in Arcade

1. Open a new web map and click on Add –> Add Layer from Web

 

Screen capture: Add Layer from Web

 

 

2. Paste in the link listed above for the Hurricane Recent – Observed Positions.

 

Screen Capture: Pasting in the link

 

3. By default, the service comes in with a basic symbol that all has the same classification.

This layer has an attribute called INTENSITY.   It measures wind speed in knots. Use this to classify the data in Arcade so it is symbolized uniformly with the Saffir-Simpson Wind Scale.  Click to “Change Style” on the point layer.

 

Screen Capture: Change Style of Symbol

 

4. Select “Choose an attribute to show” and select to create a “New Expression”.

 

Screen Capture: Adding a New Expression

 

5. Edit the “Name” (by default it says Custom) at the top to say: Assign Storm Type (Saffir) by Intensity

6. Place this code in the Arcade window:

Var INTENSITY=$feature.INTENSITY

When(INTENSITY>=137,”Category 5 Hurricane”,
INTENSITY<137&&INTENSITY>112, “Category 4 Hurricane”,
INTENSITY<=112&&INTENSITY>95, “Category 3 Hurricane”,
INTENSITY<=95&&INTENSITY>82,”Category 2 Hurricane”,
INTENSITY<=82&&INTENSITY>63, “Category 1 Hurricane”,
INTENSITY<=63&&INTENSITY>33, “Tropical Storm”,
INTENSITY<=33&&INTENSITY>=0, “Tropical Depression”, “NO DATA”)

7. It looks like:

 

Screen Capture: Arcade Code for Assign Storm Tyre (Saffir) by Intensity

 

8. What the code is saying: When the wind speed intensity is between this number and that number, identify it as this type of storm.

9. Click “OK”

10. Because of this Arcade expression, the data is now classified and is immediately prompting you to “Select a drawing style”. Select “Types (Unique Symbols)” and click on “Options”.

 

Screen Capture: Click on Options

 

 

I love that I can use my own custom made symbols (transparent PNG images) in ArcGIS Online!  It is so easy to create my own symbols, upload them to my account, share them publicly, and then use them on my maps!

1. First rearrange all your points into the proper order (Category 5-1, Tropical Storm, Tropical Depression) by dragging them up and down while hovering the mouse over the three dots on the left side.

2. Next click on the default symbol for Category 5 Hurricane and Select –> Shapes (drop-down menu) –> Custom Images.

3. Click on “Use an Image” and paste in the “Shared” text box the link listed above for the spinning blue hurricane.

Screen Capture: Pasting link copied for the custom symbol

 

4. Once this symbol has been uploaded as a custom symbol you will just need to “Select” it as it will already be in your symbol gallery. Continue individually for Category 1-4 Hurricanes.

5. Don’t worry about the size of the symbols, keep them at their default. Those will get adjusted in the Arcade expression below.

6. Because the hurricane symbol should only highlight Category 1-5 Hurricanes, for Tropical Storm and Tropical Depression categories select any “Basic” symbol and change the “FILL” and “OUTLINE” to No Color (small box with red slash on it).

7. It will look like:

 

Screen Capture: Map Symbols Window

 

8. Click “OK” and keep the Style Editor open.

 

Automatically Adjust the Symbol Size in Arcade

While ArcGIS Online doesn’t allow for setting a map reference scale (yet) as you can in Pro, there is a trick through using an Arcade expression.

Using the Saffir-Simpson Wind Scale classes you just set from above, it’s possible to define your map zoom scales (cs) in combination with wind speed classifications (INTENSITY) and set a symbol size at the end of each line.

1. In the Change Style –> Choose and attribute to show window –> Add attribute

 

Screen Capture: Add Attribute

 

2. Using the drop-down menu select “New Expression”.

3. Edit the “Name” at the top to say: Set the Symbol Size by Map Scale

4. Place this code in the Arcade window:

var INTENSITY=$feature.INTENSITY
var cs=$view.scale

When (cs<=74000000&&cs>=37000000&&INTENSITY>=137,30,
cs<=74000000&&cs>=37000000&&INTENSITY<137&&INTENSITY>112,25,
cs<=74000000&&cs>=37000000&&INTENSITY<=112&&INTENSITY>95,20,
cs<=74000000&&cs>=37000000&&INTENSITY<=95&&INTENSITY>82,15,
cs<=74000000&&cs>=37000000&&INTENSITY<=82&&INTENSITY>63,10,
cs<=74000000&&cs>=37000000&&INTENSITY<=63&&INTENSITY>33,0,
cs<=74000000&&cs>=37000000&&INTENSITY<=33&&INTENSITY>=0,0,

5. What the code is saying: When the map zoom scale is between this scale and that scale, and the intensity is between this speed and that speed, make the size this number.

6. It looks like:

Screen Capture: Arcade Code for Set Symbol Size by Map Scale

 

5. Take note that the lowest symbol size is 10  and the highest is 80 (“0” for Tropical Storms and Depressions is omitted). You will need this information again later.

6. Did you notice that the code omits Tropical Storms and Depressions (last two lines of each section the symbol size to “0”)?  This is because the spinning blue hurricane symbol only needs to symbolize Category 1-5 Hurricanes and there is another layer (with a filter) in the map that symbolizes Tropical Storms and Depressions. Also take note that the spinning blue hurricane symbol is a PNG file and the Tropical Storms and Depressions are symbolized as basic circle point symbols.  The PNG files that you upload, and standard embedded point symbology in ArcGIS Online will have different behaviors and need to have separate Arcade expressions.  This is due to minimum and maximum sizing of symbols you will see next in Step 10.

7. Now that I have the two Arcade expressions in the layer and they are applied select “Options” from the drawing style.

 

Screen Capture: Apply style to 2nd Arcade Expression

 

8. Click on “Options” for Counts and Amounts (Size)

 

Screen Capture: Set Symbols by Counts and Amounts

 

9. Remember the lowest symbol size value is 10 and the highest is 80? Enter in the these high and low values in the following six places for this sizing expression to work (Please note that if you adjust anything in your Arcade code you will need to reenter these again.  Any change will override these values):

 

Screen Capture: Six places to enter in your high and low values

 

10. Click “Done”. Both Arcade expressions are embedded within the layer and everything should be now sizing appropriately!

 

 

Sequential hurricane symbols

 

 

This is the map at 1:74,000,000:

 

Screen Capture: Map at Main Scale

 

 

At 1:18,500,000 the hurricane symbol starts to appear:

 

Screen Capture: Map at 1:18,500,000

 

 

Here is 1:5,000,000 and they are sizing nicely!

 

Screen Capture: Map at 1:5,000,000

 

 

Creating custom Arcade expressions to define symbol sizes at the varying ArcGIS Online map scales will give you more control and your map symbols more presence.  The beauty of using these Arcade expressions is that you no longer must replicate layers to show the symbols at all the varying scales, you can now just have one layer in your map and the symbols will size appropriately.

Many feature layers in the ArcGIS Living Atlas contain features for a larger region than many analysts need.  A growing number of content items are added to the Living Atlas every day that have data for all tracts, counties, schools, hospitals, or parks in the whole United States.  Most GIS analysts only need to work with features for their own immediate area.  By applying filters to these national layers, you can subset only the features that you need.

Earth’s poles have historically been some of the most poorly mapped regions on the planet.  With heightened awareness, and an overall sense of urgency around global climate change, there is a need for high quality mapping data to facilitate a deeper understanding of the impact with regard to Earth’s polar regions.

 

Sparked by President Obama’s 2015 Executive Order, and thanks to the University of Minnesota’s Polar Geospatial Center (PGC), along with their partners and sponsors, we now have high resolution topographic models of the Arctic region and the entire continent of Antarctica.

 

From monitoring and modeling the impacts of climate change over time, to field logistics, scientists, government officials, and the broader user community can leverage these great elevation maps and layers via the ArcGIS Living Atlas of the World.

 

Arctic DEM

ArcticDEM is a National Geospatial-Intelligence Agency (NGA) and National Science Foundation (NSF) public-private initiative to automatically produce a high-resolution, high-quality Digital Surface Model (DSM) of the Arctic using optical stereo imagery from DigitalGlobe.

 

Esri has been providing this data to users since 2016.  However, we recently updated to ArcticDEM Release 7, which includes 2-meter resolution elevation data for the entire region.  All of our online Arctic DEM layers and maps can be accessed and used in ArcGIS Pro, ArcMap, and custom web apps.

 

Want to see ice field and glacier changes over time?  For a quick introduction to the different layers and functionality, check out the Exploring Arctic Elevation user guide.  This story map will provide a quick overview of the different renderings and functionality, and even demonstrate how to analyze and measure ice changes over time.  It is an eye opening experience, I encourage you to give it try.  Also, since the Arctic DEM layers themselves are time enabled, change over time, and much more, can also be accomplished using ArcGIS Pro.

New to the Living Atlas is an 8-meter resolution elevation model covering the continent of Antarctica.  The Reference Elevation Model of Antarctica (REMA) is the latest addition to Esri’s polar elevation services, adding a level of detail not previously available in a full coverage map of Antarctica.  According to Ian Howat, director of the Byrd Polar and Climate Research Center at The Ohio State University, “Up until now, we’ve had a better map of Mars than we’ve had of the Earth.”  I think it is safe to say that a gap has been filled.

 

Funded by the National Science Foundation’s Division of Polar Programs, REMA Release 1 is an 8-meter Digital Surface Model (DSM) constructed from sub-meter, stereoscopic satellite imagery collected by DigitalGlobe’s Worldview satellite constellation.  The DigitalGlobe satellite imagery is licensed by the National Geospatial-Intelligence Agency, and includes data acquired between 2009 and 2017, with most collected in 2015 and 2016.

 

This elevation data is ready to use in a number of different web map views and renderings.  Some layers are optimized for visualization and some for computation.  For more details, refer to this item description or click on the image below to begin exploring with the Antarctic REMA Explorer.  While our Antarctic layers are not currently time enabled, users can find and download individual strips from different points in time by going to the ‘REMA Strips’ section of the PGC website.

It’s no surprise that today’s residential real estate has remained pricey. Rising interest rates aside, the value of most homes has gradually recovered since the last major price correction a decade ago. Gone are the days of unrestrained, unsound lending practices, and borrowers overextending themselves to the point of default or foreclosure. By and large, property values across the price spectrum have appreciated since the last recession. As this trend continues to be prevalent within markets containing premium-priced properties, we’re faced with a growing number of towns with million-dollar homes. But how many?

Show me the numbers

With over 78 million owner-occupied homes in the US:

 

  • More than 2.1 million homes are valued between $1 million and $2 million.
  • Nearly 600,000 homes are valued at $2 million or more!
  • New York City tops the list with more than 68,000 homes valued at $2 million or more!

 

These numbers sound impressive, but million dollar plus homes represent a relatively small segment of the US housing stock. However — an interesting data discovery here is that the percentage of million-dollar properties has more than doubled since 2010.

Across the US, you can see that majority of these million-dollar plus cities are concentrated along the east and west coast regions of the US.

 

2018 High Median Home Values

Where does the data come from?

Esri provides demographic data for 137 countries covering 90% of the world’s population. Esri’s in-house US Data Development team, which consists of demographers, economists, analysts, and programmers, develop independent demographic and socioeconomic updates and forecasts for the United States.

In addition to processing US Census and ACS data, the US Demographic Data Development team produces unique and innovative databases such as Tapestry Segmentation, Consumer Spending, and Market Potential which have become industry benchmarks for understanding communities. To learn more about Esri’s data accuracy, view www.esri.com/accuracy.

Why track the multi-million dollar housing market?

In most cases across the country, housing affordability continues to be a major concern. As a result, Esri’s US demographics team recognized the importance of adding more detail to the home value distribution.

“In many markets home values have surpassed their pre-recession highs. As more homes breach the million-dollar valuation mark, our home value distribution has been expanded to reflect current prices,” says Esri Chief Demographer, Kyle R. Cassal.

Show me the data

Taking a step back, if analysts wanted to identify areas with extreme affluence, the highest home value range used to be capped at $1 million or more. Capturing today’s growing multi-million-dollar housing market meant redefining and expanding Esri’s 2018 and 2023 home value ranges to offer more detailed data of owner occupied housing units with home values that would exceed $1 million. The result…

… a home value database that includes 3 new multi-million-dollar ranges:

$1,000,000-1,499,999

$1,500,000-1,999,999

$2,000,000+

A picture is worth… well, one or two million bucks!

One of the best ways to show you the impact of these new data ranges is with a map. Esri’s US demographics team created the 2017-2018 Home Value Comparison web map for the Manhattan, New York area using ArcGIS ’s smart mapping technique called Predominance Mapping.

The panel on the left displays the predominant home value range from Esri’s 2017 home value distribution by Census tract. The top end of this distribution of owner occupied housing units is capped at $1 million or more and symbolized by the deepest purple bubbles.

The panel on the right displays Esri’s newest 2018 distribution utilizing the three new top end home value ranges. The deep red bubbles symbolize the new higher top-coded home value range.

 

 

Using the predominant mapping technique, you immediately see the impact of the new intervals. Look at how the finer resolution ranges distinguish the smaller pockets of the highest valued homes at $2 million and beyond.

So, what does your town look like?

With our latest release late last week, Esri Vector Basemaps updated map styles and added features, increased the number of localized maps, and published a new creative style. We added new HERE data to improve the maps. Our Community Maps Program also provided new data. See these blogs by Shane Matthews for specific contributions.

Style Improvements

Display of features improved across several basemaps. Street Map, Streets with Relief, and the Hybrid Reference Overlay changes increased city font size, added beach sprite, and made JSON layer names more user friendly. New pavement markings enhance larger scales, especially at the campus level. The updated Topographic vector map displays arrows and handicapped parking symbols. This Reference Document provides information on recent changes and structure of our basemaps. Bookmark this group or search the Living Atlas of the World (Basemaps category and Vector Tiles sub-category). Similarly, Esri vector maps are accessible in the ArcGIS.com map viewer and ArcGIS Pro in the same Living Atlas Basemaps category and Vector Tiles sub-category search.

Basemaps Localization

We added three new languages to our collection of localized basemaps. Our current total is nine different languages. Each one is available in nine different basemap styles. New are Italian, Polish, and Brazilian Portuguese. These join previously released Modern Chinese, French, German, Japanese, Russian, and Spanish. To make localized maps the default basemap, change the organization’s Region and Language in the General settings. Also, change the Map setting to display Esri vector basemaps for the Gallery. Each language above is linked to a group of web maps. Localized labels display primarily at small scales; however, we are expanding translations across more feature classes and at more scales. Additional languages will be deployed in subsequent releases.

The Thomas Fire

 

The Thomas Fire was a devastating wildfire of historic proportions that burned through parts of California’s Ventura and Santa Barbara Counties. The fire started on December 4, 2017, north of Santa Paula and near the Thomas Aquinas College, the fire’s namesake. Driven by strong Santa Ana winds that persisted for nearly two weeks, and a large amount of available fuel, the fire grew rapidly. By it’s official end on January 12, 2018, the fire had become the largest in California history (since superceded by the Mendocino Complex Fire).

 

The fire destroyed over a thousand structures, with hundreds more damaged. It generated over $2.18 billion in damages, injuring one firefighter and claiming the life of another, along with one resident who died in an auto accident while fleeing the area. The destruction didn’t stop with the fire, as post-fire rains created massive mud flows that claimed 21 lives, destroyed 129 residences, and damaged over 300 more. See the Thomas Fire on Wikipediafor more information.

 

The Thomas Fire map

 

In this tutorial you will learn more about the fire using ArcGIS  analysis tools and content available from the ArcGIS Living Atlas of the World to author a map showing the  fire perimeter, learn more about the population and demographics of the impacted area, and view satellite imagery before, during, and after the fire.

 

You will use the following steps:

 

  1. Find the fire location
  2. Add and save the fire perimeter
  3. Geoenrich the perimeter, adding population and other demographic information
  4. Add Sentinel-2 imagery for dates prior to the fire, during the fire, and after the fire was fully contained.
  5. Adjust the imagery to reveal specific details

 

Find the fire location

 

Step 1 – Use Search to find the location.

 

The first step in making the map is to navigate to the fire location. Open a new web map, use search and enter Santa Paula, California. You can also use Thomas Aquinas College, Santa Barbara County, or Ventura County as the search string.

 

 

Add the Thomas Fire perimeter

 

The USA Wildfire Activity layer from the Living Atlas displays current and inactive fire locations and perimeters. From your web map, Browse the Living Atlas to find the USA Wildfire Activity layer, then add it to your map.

 

Step 1 – Click Add, then Browse Living Atlas Layers.

 

Step 2 – Search for “wildfire” to locate USA Wildfire Activity, then click + to add the layer to your map.

 

Step 3 – Display the Thomas Fire perimeter.

 

By default, the  USA Wildfire Activity layer has the active fires locations and perimeters toggled on. Since the Thomas Fire is no longer active, you will turn the default active fire sublayers off, and turn the inactive perimeters on. Click the layer title to reveal the sublayers, and toggle the layers as shown below.

 

Zooming out, you can view the extent of the Thomas Fire.

 

 

Create a copy of the perimeter

 

Inactive fire locations and perimeters are eventually phased out from the service, so you will create a copy of the perimeter to ensure it will always be available in your map. You will use the Analysis tools to create a new feature layer from the existing Thomas Fire perimeter.

 

Step 1a – Open the Analysis tools.

 

Step 1b – Open the Find Locations group.

 

Step 1c – Click Find Existing Locations.

 

Step 2 – Complete the tool steps (numbered in blue) as follows.

 

In tool step 1, choose the USA Wildfire Activity-Inactive Perimeter sublayer.

 

Step 3 – In tool step 2, construct the attribute query expression to find the Thomas Fire perimeter. The expression looks like this:

 

Step 4 – Complete the tool inputs for Find Existing Locations by entering a Result layer name in tool step 3, then click Run Analysis.

 

 

Enrich the fire perimeter polygon

 

How may people lived in the burn area? How many households were impacted? What is the population like? These questions can be answered by using geoenrichment tools that tap into Living Atlas data to add attributes describing these characteristics. These data are added based upon the area of the polygon using apportionment, the full details of the implementation and methodology can be viewed in the Data Apportionment documentation.

 

Step 1 – Open the Analysis tools, and choose Enrich Layer.

 

Step 2 – Complete the tool steps in the Enrich Layer tool. First, select the layer you created in Step 8 in tool step 1.

 

Step 3 – In tool step 2, click Select Variables to open the Data Browser.

 

Step 3 – Choose the following attributes to enrich the fire perimeter:

 

  • 2018 Total Population (Esri)
  • 2018 Total Households (Esri)
  • 2018 Median Household Income (Esri)
  • 2018 Dominant Tapestry Segment Name (Esri)

 

Begin by selecting a category:

 

Then choose the attributes.

 

To go back to the categories, click the category box in the upper left:

 

Step 4 – After selecting the attributes, complete the tool steps as shown below, then click Run Analysis.

 

 

Add Sentinel-2 imagery

 

Sentinel-2 is multispectral, multitemporal global imagery obtained via two satellites placed in the same orbit by the European Space Agency, and phased 180 degrees from each other. Every location on the planet is revisited every 5 days. This Living Atlas imagery layer pulls content directly from the source Sentinel-2 archive on Amazon Web Services (AWS), and is updated daily. The layer can be easily added to web maps (and scenes), and rendered in different ways to highlight specific characteristics. In addition, the imagery can be filtered by date.

 

Step 1 – Add the Sentinel-2 imagery layer from the Living Atlas.

 

This is similar to what you did in Step 3, but search for Sentinel-2 instead.

 

Step 2 – Remove the default filter on Sentinel-2.

 

The default filter on the Sentinel-2 layer will display the most recent and clearest imagery available. You will want to search for all imagery around the dates of the fire, even smoke-filled imagery, so remove the filter so all imagery will be available. After adding the layer, click the Filter icon to display the current filter, and remove it.

 

Step 3 – Click More Options (…) and choose the Image Filter.

 

You will use this filter to search for available imagery around the dates of the fire.

 

Step 4 –  Select the imagery at the desired dates.

 

Adjust the time slider around the dates of the fire. The available imagery will be listed. Hover over each to display the coverage footprint in yellow on the map. Identify the date, then select the images that cover the fire perimeter. Repeat the process to create layers for before, during, and afterwards. Note that to cover the entire fire perimeter you will have to select two images, then click Add To Map combining both into one layer.

 

When moving on to the next date, remember to uncheck the previously selected layers.

 

The fire started December 4, 2017, and officially ended January 12, 2018. Using the image filter to add Sentinel-2 imagery for the following dates:

 

  • October 23, 2017 (before the fire began)
  • December 7, 2017 (during the fire)
  • January 16, 2018 (after the fire)

 

 

Adjust the imagery display

 

To glean more information from multispectral imagery like Sentinel-2, you can choose a renderer that highlights specific characteristics of the imagery. For example, you can choose renderers that highlight healthy vegetation, geology, moist areas, and more.

 

The default renderer is Natural Color with DRA (Dynamic Range Adjustment). In this section you will apply the following renderers to the imagery layers you have added to your map:

 

  • October 23, 2017 (before the fire began) – use the default Natural Color with DRA.
  • December 7, 2017 (during the fire) – use Short-wave Infrared to highlight actively burning areas and hotspots.
  • January 16, 2018 (after the fire) – use Normalized Burn Ratio to highlight the burned areas.

 

Step 1 – From the layer options, choose Image Display.

 

Step 2 – From the list of renderers, choose the one that you want, then click Apply.

 

Repeat the steps for the other layer, and save your map when finished.

 

Summary and results

 

Using content from the ArcGIS Living Atlas of the World and ArcGIS  capabilities, you have authored a map that delivers enhanced information about the Thomas Fire.  Demographic attributes have been added to the fire perimeter delivering information about the impacted households and enabling us to learn more about those that lived there.  Sentinel-2 layers of different vintages have been added, and specific spectral characteristics of the imagery have been rendered to highlight active burn areas, and post-fire impacts. These are reviewed below.

Geoenriched fire perimeter

 

After configuring the layer pop-up, clicking the perimeter provides more information about the population. The total number of acres was in the original perimeter, but geoenrichment has added the population, number of households, median age, median household income, and dominant Tapestry segment (Exurbanites). The dominant segment is a link that opens detailed documentation about Exurbanites, helping us learn more about the characteristics of the impacted residents.

 

Pre-fire Sentinal-2 imagery December 23, 2017

 

Using the default Natural Color DRA renderer, this image show the normal conditions and appearance for the burn area.

 

During-fire Sentinel-2 imagery December 7, 2017

 

Captured a few days after the fire started, and using the Short-wave Infrared renderer, this layer allows us to peer through the smoke and clearly see the active burn areas.

 

Post-fire Sentinal-2 imagery January 16, 2018

 

This layer uses the Normalized Burn Area renderer to highlight the burned areas in black.

*****

Vector Tile Layers can be used to create multi-scale maps that are efficient, high-resolution and customizable, and this includes Vector Basemaps. Esri’s Living Atlas Content Team has created vector tile versions of most of our traditional basemaps (plus some new ones), and these work well in themselves …

 

 

But have you ever had that moment where you thought ‘This basemap would work really well, if only …’?

 

What are Vector Basemaps?

 

Our vector basemaps originate as a Vector Tile Package, built in and generated by ArcGIS Pro, then published with a generic style. It establishes the maximum level of content available and a defined scale range for each layer of information. Separate style documents are created in JSON Code for each of our basemaps, although they do not necessarily use all of this content, or the available scale range.

 

The Vector Tile Package

 

A vector tile package contains the vector tiles, and various formatting documents. Of interest to us is the Resources Folder, which includes:

 

Fonts – Any font that is used in the ArcGIS Pro map.

 

Sprites – PNG Raster images created for special effects, such as textured patterns and point symbols. In most circumstances, once these have been exported from Pro, they are not editable. However, we have created alternatives for our different core maps.

 

Styles – A root.json file that establishes the symbolization of the map detail. This is editable, and it is the key to the discussion here. We can make changes to this code to affect color, line weight, label size/font, and scale range … either directly, or through an editing app.

 

How do I work with them?

 

The Vector Basemaps Reference Document, is a downloadable PDF describing how our maps are structured. As the maps themselves have become more versatile (and we are trying to improve them all the time), our layer structure has become more complex. This document will help you to find your way through. It may be a little confusing at first, but the more you work with it, the more it will make sense. Don’t feel you have to learn it before you start work though (It’s a ‘reference’ document!).

 

We provide two editing apps to help you on your way (Note that both are in beta, so details could change without warning). Both require you to sign-in to an ArcGIS.com organization.

 

The first is new as of 2018.

 

The ArcGIS Vector Tile Style Editor is an intuitive app that leads you through most of the simpler changes you can make to the map style. For most tasks this will make life much easier for you.

 

 

The JSON Code Editor has been available for a while. It pairs the JSON style with a preview map as an easy way for you to work directly with the code and see the results. If you are confident in your ability to work with code, the JSON style file gives you access to some more sophisticated options. It is a requirement if you want to add data layers to the style.
