Single sign-on uses a school district’s identity provider software (such as Microsoft Active Directory or Google G Suite) to support student authentication on devices, when accessing the school network, or when using district software.  Single sign-on provides three broad categories of benefits to teachers: increased instructional time, stability and support across the school, and reduced teacher liability.   Read more >>

Dear Colleagues:

 

You have likely seen information about the new User Types coming out in the December 4th release of ArcGIS Online. Some of you have asked how these new User Types will affect Education program offerings, therefore we wanted to provide an update.

 

Overall, not much will change immediately for those of us with Education program licenses, such as Site/Institution licenses, Lab Kit/Academic Department licenses, or Schools bundles.  However, these changes lay the groundwork for streamlining ArcGIS administration even further and we will see additional changes in the coming months.

 

What is changing in this December 4th release:

 

  • Level 1 named users will automatically be converted to Viewer User type.
  • Level 2 named users will automatically be converted to a Creator User type.
  • All capabilities of each user type remain the same.
  • Roles remain the same (Administrator, Publisher, User, Custom Roles, etc.).
  • An updated look/interface and updated Licenses and Members pages and workflows.  
  • For existing users, any already assigned licenses/entitlements will remain assigned.
  • For new users, licenses/entitlements of ArcGIS Pro and other apps (Business Analyst, Insights, etc.) will need to be assigned, as before.

 

Additional information on changes in this December 4th release can be found here.

 

What does the introduction of the new User Types mean over the coming months (i.e. future releases):

 

  • We anticipate additional changes in the March 2019 ArcGIS Online release which will provide the ability to configure additional app assignments in enterprise login settings.
  • We will continue to work towards automated provisioning of all apps included in Education program offerings so you can easily and efficiently provide your users with access to the full capabilities of ArcGIS.

 

In summary, this December release introduces some exciting new changes, and will see additional changes over the coming months. In the meantime, we continue to recommend enabling enterprise logins, if you haven’t yet, and following these best practices for administering ArcGIS.

 

Please let us know if you have any questions, feel free to post here.

A true craftsman uses skill developed deliberately, with attention to detail, and often with signature elements. Lyn Malone is a craftswoman. A teacher of social studies in grades 7-12 from 1970-2002, and provider of professional development since, Lyn designed lessons, activities, and projects used by thousands that covered key content, but did so with the eye of an artist and mind of an analyst. Even her casual conversation uses complete sentences that vary in structure.

 

"My Bachelors degree was in history, and my Masters in American Civilization, which is much more interdisciplinary than straight history." Her early teaching career spanned the breadth of the social studies, all in senior high. "But I always loved geography, always loved maps. I went down to Middle School in 1983, and started going in evenings to Rhode Island School of Design," building over the years a certificate in scientific and technical illustration. She started doing maps, and illustrations of historical artifacts, but that industry shifted to digital faster than could a full-time teacher who was also working with the new Rhode Island Geography Education Alliance.

 

As with many educators in the 1990's, GIS did not come easily for Lyn. "I went to at least three full-day workshops introducing GIS, and loved them, but couldn't make anything happen. That's why the 1998 institute" [an intense, two-week, day-long, GIS boot camp for teachers] "was such a huge boost." What followed were new activities, interdisciplinary, sometimes in concert with colleagues in other departments, schools, and even states, and built always from the perspectives of both designer and analyst. "I loved working with data, especially about population. Not so much building it, but finding and discovering what could be done with data others had assembled."

 

In 2000, Barrington Middle School won the first "Esri Community Atlas" contest, which challenged students to craft a website with simple but powerful maps portraying the community. Lyn and three students from grades 7-8 were invited to present their work on stage at the 2000 Esri User Conference. It was so well crafted and delivered that Roger Tomlinson ("the father of GIS") stood in line to talk with them, General James Clapper congratulated them and handed each student a commemorative coin, and Esri president Jack Dangermond whispered "We have to do this again," launching what has become a regular UC Plenary highlight.

 

With signature panache, Lyn models the latest in GIS vocabulary at T3G,

and dons foul weather gear to model GeoNews for a class.

 

Those attributes earned Lyn a spot co-authoring a ground-breaking curriculum package, Mapping Our World (in several versions), followed by Community Geography. In 2009, Lyn helped launch Esri's educator institute, Teachers Teaching Teachers GIS (T3G). Numerous events in New England and far beyond, for educators and the wider public, have featured her activities and presentations, always models of focus, detail, and elegant design.

 

Describing T3G as "Part boot camp, part religious revival," Lyn captures the essence.

 

Eventually, though, even artisans slow down. With almost five decades of instruction behind her, Lyn is looking forward to a little more leisurely travel, reading, art, and maybe classes, with fewer deadlines. But the many thousands who have engaged with her lessons stand a chance of seeing a complicated world more clearly, with geographic patterns and relationships illuminated through GIS. Thank you, Lyn!

Greetings all and, if you are in the USA, Happy Thanksgiving. This “where does Thanksgiving dinner come from” story map: https://storymaps.esri.com/stories/2017/thanksgiving-dinner/ could be useful for many reasons:  

 

1)   Like many good maps, it is great for examining spatial patterns, and also for challenging some preconceived notions (did you know that Wisconsin was so prominent in growing green beans, for example?). 

2)  The excellent use of symbols and other cartographic techniques might be useful discussion points in geography, GIS, and cartography courses.

3)  Examine the metadata--this map was created from data from the USDA Census of Agriculture.  How did the data get compiled?  

4)  How can you create a series type of story map like this one, on your own topic of interest?

5)  Use this map to spark some “spatial” discussions with your friends and family.   Enjoy.  And thank a farmer!

At the 2018 Esri User Conference, two teachers received the "Making a Difference" award. They teach social studies and English at the Math, Science, and Technology Magnet Academy of Roosevelt High School, in Los Angeles. Watching the 11-minute award video, which included the premier of a brief video about the research project, provides a quick glimpse of the power of GIS in instruction and the impact of a meaningful project. But for those of us who watched class after class engage in this fashion, this video is the proverbial tip of the iceberg.

 

Students engage deeply, powerfully, in a justice-based topic they choose. They conduct authentic research, seeking patterns in the data, and relationships between the topic and the lives of those around them. These "maptivists" invest many hours learning GIS technology, struggling with data, establishing time management habits, designing effective presentations for public display, growing team sense while gaining a sense of self, becoming empowered.

A new YouTube playlist presents a quartet of videos (shortcut: esriurl.com/maptivists): (1) the quick synopsis from the 2018 Esri Conference, (2) a profile of a single student a year after the experience, (3) an interview with entertainer and entrepreneur will.i.am who introduced Esri to the school, and (4) a deep dive into the design and conduct of the research project. Watching the full award ceremony video and then playlist segments 2, 3, and 4 will show the immense power of good tools and methods in the hands of good teachers.

 

Any school can have these GIS tools for free. Any teacher can learn these approaches. Every student deserves the chance to immerse in such rich learning, often. Please watch, learn, and share.

Welcome to this series of GIS Workshops!  These are designed to help you become excited about and enabled to use web GIS tools to solve problems and analyze spatial patterns, relationships, and trends.

(3) The Power of ArcGIS Online

(3a)  Spatial Joins to the ArcGIS Online Living Atlas of the World

A spatial join is a GIS operation that affixes data from one feature layer's attribute table to another according to its location. Spatial joins begin by selecting a target feature and comparing it spatially to other feature layers.  Spatial joins have been used for years, for example, to determine how many water wells are in a drainage basin, or businesses in a census tract, or the number of earthquakes that fall within specific countries over specific time periods.  Let's take this last example and apply it to the changing paradigm that Web GIS represents.  You can now join data to the cloud!

 

Let us say that I want to determine how many earthquakes occurred in the past 30 days according to the USGS National Earthquake Information Center.  The way I have done this for years in ArcGIS Desktop was to gather two data layers - a point layer for earthquakes, and a polygon layer for world countries, and perform a spatial join.  Nothing is wrong with that method, and it continues to work well in ArcGIS Pro, for example.  But let's say I want to do that in ArcGIS , and I don't want to download anything.  This is accomplished with an analysis tool in ArcGIS --Join Features.  To use the analysis tools, you have to be signed in to ArcGIS  and have a publisher role.  

 

To begin, start with my web map:  

http://denverro.maps.arcgis.com/home/webmap/viewer.html?webmap=63a6261d7afa48878a52a4c7127f624e - the 

Earthquakes starting point map.  It contains data layers that are streaming from the USGS earthquake center, in this  case, the last 30 days of earthquakes. 

 

Sign in to ArcGIS Online > Analysis > Summarize Data > Join Features.  Once the Join Features analysis tool is engaged, I find World Countries (generalized) in the Living Atlas of the World.  This is your target layer, so named because my goal or "target" is to create a choropleth map by country polygons.  The layer to join to these polygons is my earthquakes layer that is streaming from USGS.  The type of join is "intersect"--if an earthquake is inside or "intersects" the country polygon, you want it to be considered.

 

 

Spatial Join 2

Here is how I found the Living Atlas content, after searching on World Countries, I selected the generalized data set:

 

Spatial Join 1

I filled in the remainder of the Join Features dialog box as follows:  I chose the one to one operation; I added statistics so I could determine average magnitude and depth by country, which I thought would be interesting (as I explain in this video, always be curious!) my resulting layer and I unchecked "use current map extent" just in case my current extent happened to be cutting off any outlying islands in the South Pacific, for example, and then > Run Analysis:

 

Spatial Join 3

 

The results are below, with all countries defaulting as single symbol. 

Spatial Join 4

You will change the style shortly, but before you do, let's examine the new table of data.  The "join count" field contains the number of earthquakes by country:

 

Spatial Join 5

The average magnitude and average depth have been saved as fields in the new layer:

 

Spatial Join 6

 

Next, use Change Style to symbolize the countries on Join_Count, as follows:

 

 

Spatial Join 7


Because the USA contains so many earthquakes, the default Counts and Amounts symbology lumps most countries into one category.  The reason why is in part because the USGS earthquake center is in the USA.  It is in Golden Colorado; I used to give tours there as a USGS employee; a fascinating place that I recommend highly for you to take a tour in next time you're in Colorado.  The earthquake center receives transmitted signals of information from the global seismic network, but it also senses ground motion from nearby earthquakes in the western USA.  So, it senses more small earthquakes in the USA than it does for other countries, resulting in a higher number for the USA.  This is all a critical part of knowing your data, as I write about weekly on the Spatial Reserves data blog.  So, under Options, I changed the classification to Quantile with 5 classes, as follows:

 

Spatial Join 8

 

The result is below.  Now I have a better sense, with a choropleth map, of the frequency of earthquake by country.  Given a ocean polygon layer, I could even map oceans by earthquake frequency.

 

I would like to make just a few adjustments.  Because over the last 30 days, according to the USGS, earthquakes had occurred in only 42 countries, and 254 polygons exist in the generalized world countries data set, countries with no earthquakes have no symbol or color:    

 

Spatial Join 8b

 

This looks a bit odd.  My goal is to show countries with no earthquakes over the past 30 days with a pale yellow color.  This is easily remedied with a few keystrokes.  The easiest way to do this is to use the Add Data button, add the generalized world countries from the Living Atlas of the World, and change its style to pale yellow with a yellow outline.  Once done, I moved its position to be located underneath my joined earthquakes layer.  I also moved the earthquakes to the top of the contents so that my map users could more clearly see them.  I also labeled the countries with the number of earthquakes that occurred within each one.   The resulting map is here. 

Spatial Join 9

 

Try the Join Tables to ArcGIS  on other data sets.  It can be accomplished in just a few steps but the results are powerful.  Think of ArcGIS  and the Living Atlas as a vast storehouse of data that you can join your own data to for rich analysis.

Using geotagged images can be a great way to capture verifiable data in a project-based learning or citizen science exercise. Students can collect data with photographs, share their images to a common folder, and then use this script to map the pictures.

 

Geotagged images are taken constantly, usually by people with smartphones, perhaps even by people unaware that latitude-longitude information is embedded in the header of the images.  For many casual users, seeing these images in a smartphone’s built-in Photo app with a simple map feature is all the mapping they’ll want.  But, for the carto-literati ...
