ArcGIS Living Atlas of the Worldprovides foundation elevation layers to support your work in 2D and 3D. Over the last couple of years, Esri has been developingWorld Elevation Servicesprimarily from best authoritative data from open sources and contributions to the Esri Community Maps for Elevation program.
We are glad to announce that we are adding global elevation data fromAirbus Defence and Spaceto further enhance Esri Elevation Layers (Terrainand TopoBathy) and Tools (Profile,ViewshedandSummarize Elevation).WorldDEM4Ortho, which is based on the global WorldDEM dataset, has a resolution of 0.8 arc second (approx. 24 meters) with a vertical accuracy of ~ 4 m (LE90%)* on a global scale. Covering the entire earth’s land surface (excluding the countries of Azerbaijan, DR Congo and Ukraine), this is the most consistent and accurate satellite-based elevation model on a global scale. This dataset brings many improvements over areas with SRTM 30 m coverage and areas above latitudes of 60 degree north and south.
This dataset is now available in world elevation layers and tools to all ArcGIS Online subscribers. Let’s see few examples showing enhancements over SRTM 30 m.
Mount Kilimanjaro, Tanzania – a dormant stratovolcano and the highest mountain in Africa at an elevation of 5,895 m (19,341 ft) above sea level (SRTM 30 m vs WorldDEM4Ortho 24 m)
A portion near Craters Highland, Tanzania depicted with newly released WorldDEM4Ortho 24 m (bottom) showing improvements over SRTM 30 m (top)
Cotopaxi, Ecuador– an active stratovolcano in Andes mountains and the second highest summit in Ecuador at an elevation of 5,897 m (19,347 ft) above sea level (SRTM 30 m vs WorldDEM4Ortho 24 m)
Ojos del Salado—the highest active volcano in the world at 6,893 m (22,615 ft) on the Argentina–Chile border (SRTM 30 m vs WorldDEM4Ortho 24 m)
Nevado Sajam, Bolivia —an extinct stratovolcano and the highest peak in Bolivia at 6,542 m (21,463 ft) above sea level (SRTM 30 m vs WorldDEM4Ortho 24 m)
Mount Fuji, Japan – an active stratovolcano and the highest mountain in Japan at an elevation of 3,776.24 m (12,389 ft) above sea level (SRTM 30 m vs WorldDEM4Ortho 24 m)
The world elevation image services (Terrain and TopoBathy) are a collection of multi-resolution and multi-source elevation data that can be used for visualization (such as multi-directional hillshade, tinted hillshade) and analysis. When using for visualization, the service will automatically display the data from best source at a given location, thus providing a seamless user experience. With this update, Airbus WorldDEM4Ortho will take priority over SRTM when rendering visualizations.
While doing analysis in ArcGIS desktop clients (Pro or ArcMap), you need to choose a dataset from the service depending upon your analysis requirements. These services being dynamic image services provides the ability to make a request in user defined coordinate system, cell size and extent which make these suitable to use for analysis. Each dataset in these services has a unique identifier and a query can be defined based on ProductName or Dataset_ID. For example, a definition query of “ProductName” = ‘Airbus_WorldDEM4Ortho_24m’will filter data pertaining to the Airbus WorldDEM4Ortho grid only. To make a request in user defined parameters, use theMake Image Server Layer geoprocessing tool. This tool generates a temporary layer that can be used as an input in other geoprocessing tools to perform analysis.
Airbus WorldDEM4Ortho is also rolled out in Elevation Analysis Tools (Profile, Viewshed and Summarize Elevation) and can be invoked in these tools by selecting 24 m option from the drop-down menu of DEM Resolution parameter.
For more information about the various data sources available in World Elevation services, check out Elevation coverage map. Esri will keep improving World Elevation Services, Tools and derivative products by including high resolution data from open source and Esri Community Maps program. Additionally, to contribute high-resolution elevation data to Living Atlas of the World, check out the Esri Community Maps for Elevation program.
* Excluding urban areas which are flattened (DTM like areas), area of Antarctica and areas where substituted datasets are used.
Updating your existing web maps or Pro projects to use thenew version (v2) of theEsri Vector Basemapscan be accomplished with a just a few clicks of the mouse. The benefits of using the Esri Vector Basemaps were shared in arecent blog post and we updated the vector map content again this week. This latest release includes newer HERE data for both North America and Europe as well as 14 new and 16 updated contributions added through ourCommunity Maps Program.
V2is the current version and the only version we’re updating now. If you’ve been using vector basemaps prior to December 2017, you need to update the version in your web maps or in Pro. The basemap doesn’t automatically change. This blog walks you through how to find out if you’re using an older version of the vector tiles and how to make the upgrade to our new version (v2). These steps cover the most common scenarios for making the switch in ArcGIS Online or Pro.
Question: How can I tell if I’m using an older version of the Esri vector tiles?
Answer: In your web map’s Contents, expand the basemap layer and view the More Options dropdown (three blue dots). Click on Show Item Details.
The item page opens and there many “warning signs” that this map is an older version. Item 6 is the most relevant if you made your own copy of and/or customized an Esri Vector Basemap layer.
Title contains “…(Mature Support)”
Summary states “This (v1) vector tile layer is in mature support…”
It shows it’s Deprecated next to the thumbnail
The item description begins with an important note…
1) WHO: Users in an organization already configured to use the default Esri Vector Basemap gallery.
If you don’t already have this option, but want to add it to your ArcGIS Online org, your admin can:
Click Edit Settings under Organization
Select the Map tab
In the Basemap Gallery section check “Use Esri vector basemaps in supported ArcGIS apps”
You can also include vector basemaps in your custom gallery. This gallery will then be used in all supported ArcGIS apps.
HOW TO: From the Basemap tab in ArcGIS Online, select one of the Esri Vector Basemaps from this default gallery and resave your web map.
In Pro, the process is similar. Under the Map tab, Basemaps, select one of the vector basemaps from the gallery. This will replace your existing basemap with the new version (v2) vector basemap, no matter if it was an older (v1) vector basemap or a raster basemap. These vector web maps in the gallery will always be configured to contain the latest version of the vector layers.
2) WHO: Users who aren’t using the default Esri Vector Basemap gallery, but are using an Esri vector layer (v1) as their basemap or as another layer.
This approach adds a new (v2) layer you can configure as a basemap or keep as a separate layer in your web map. Follow this approach if you’re updating to a vector basemap from a raster basemap or if you’re updating from your own customized basemap.
HOW TO: The most direct route in ArcGIS Online is to Add > Browse Living Atlas Layers.
This approach is similar in ArcGIS Pro. There you search through Catalog > Portal > Living Atlas. In the map viewer, you can also select Search for Layers: from ArcGIS Online, in your Content, or in your Organization, etc. You still enter through the Add tab and set your search options accordingly.
In the Browse Living Atlas Layers, narrow your search by showing onlyEsri layersfrom theEsri Basemapscategory and limiting the search with keyword: vector.
Hovering over the map thumbnail displays a description of the layer. In this example World Navigation Map has the summary: This (v2) vector tile layer… You have options how to add this to your web map: As Layer or As Basemap.
If you are replacing only one layer in your basemap, you can Add to map > As Basemap. This option will entirely replace the existing basemap in your web map with this new version (v2). This works well for styles such asStreets,Streets (at Night), andNavigation.
If you added one of these multi-layer styles As Basemap, it would remove ALL the other layers in the basemap. For example: Imagery Hybrid basemap includes a raster Imagery layer plus the vector Hybrid Reference layer. You only want to update the vector layer. That’s why Add to map > As Layer is the option for these styles.
For these basemap styles, Add to map > As Layer and manually configure these new layers in your basemap (see (A) below). When you add as layer, the new version (v2) layer is added as the top layer in your Content (B). Next, you should remove the older (v1) layer from within your basemap (C).
Move the new layer into the basemap (see (D) below). Within the basemap you can order the layers so they appear as you intend (Move up/Move down). The result looks like where you started, but now includes the new (v2) layer (E). In the case of the canvas styles or styles with relief or imagery, you will need to set the (v2) layer as a reference layer to ensure the correct display (F). You can always check the version of the map by clicking on the Show Item Details from the layer dropdown menu as detailed earlier in this blog. Save your web map.
These approaches to updating your web maps allow you take advantage of our new version (v2) of the Esri Vector Basemaps. To stay up-to-date on vector basemap news, see our collection of blogs.

From hundreds of new and refreshed +Metro cities, to a massive broad area update of the United States, we have been very busy producing, curating, and publishing content forWorld Imagery.
DigitalGlobe Basemap +Vivid +Vivid is our primary imagery basemap solution for providing high quality, high resolution, broad area global imagery. We have introduced new coverage for areas that previously lacked high resolution imagery, and we continue to refresh existing coverage. Recent and pending +Vivid Updates include: Afghanistan, Australia, Canada North West Territories and Yukon, United Kingdom, United States, and coming soon…a refresh of Western Europe.
The release of +Vivid across the United States is a significant step forward in terms of optimizing the overall depth, breadth, and currency of World Imagery coverage…
Improved Currency. As we had already done for Western Europe, we have now replaced the existing Bing Aerial imagery across the US. The Bing Aerial imagery was beyond the targeted currency of World Imagery (>5 years) and introducing +Vivid allowed us to bring the imagery to within 0-3 years of currency. However, because the Bing Aerial imagery still offers significant value to some of our users, it will continue to be available through ourWorld Imagery (Clarity)basemap tile service.
Improved detail – Large Scales. +Vivid for the CONUS provides a high level of detail (50cm resolution) with very good visual consistency which means that we can deliver greater consistency across the country and across zoom levels, from medium to large scales. Given these advantages, we have replaced most of NAIP in World Imagery. Still need access to NAIP? Not to worry, users can still access NAIP as an Imagery Layer through ourNAIP Image Service.
Improved detail – Medium Scales. Our user community has requested improved quality, detail, and currency at the mid-range scales of World Imagery. The introduction of +Vivid has provided some key visual improvements, including coastal regions, which will enable us to follow through with this request. More details to come on this early in 2018….
Tradeoffs. While +Vivid generally provides significant improvements for World Imagery, and the source product is curated to remove most cloud coverage, clouds can occur in some locations. If a user should encounter clouds over a location of interest, the aforementioned World Imagery (Clarity) and NAIP Image Services are excellent options for alternate sources of imagery.
Sample comparison of NAIP 2016 vs +Vivid 2016 over Lower Manhattan…
DigitalGlobe Basemap +Metro
In our ongoing effort to ‘keep it fresh’, since October, World Imagery has received new imagery for 340 +Metro cities. That is more than half of our total +Metro city count! More than 300 of these cities are second generation publications…fresh imagery for cities that we just published within the previous year! Check outWhat’s New – DigitalGlobe Basemap +Metrofor some highlights and a full listing of cities.
Community Maps Imagery
We continue to receive many high quality and high value contributions through ourCommunity Maps Program. World Imagery has recently received many significant Community Maps contributions. Honorable mention goes out to the Florida DOT in the United States and a number of regional contributions across New Zealand…
