World Historical Gazetteer
The World Historical Gazetteer (WHG) is providing a collection of content and services that permit world historians, their students, and the general public to do spatial and temporal reasoning and visualization in a data rich environment at global and trans-regional scales. Check it out!
Low Reservoirs
In California, some of our reservoirs are still low. Check out this article and slider apps comparing satellite images of the reservoirs 5 years ago and today.
Shaded Relief Maps
Looking for a unique gift for someone who loves maps? Check out these shaded relief maps. They are flat 2D maps, but really look like they are jumping off the page in 3D. My guess the bigger the map you get, the better 3D effect on your eyes! Check it out.

For GIS users who want to take their analysis a step further, ESRI offers ArcGIS Living Atlas (“Living Atlas”) for an enriched demographic data experience. Living Atlas connects users with demographic data layers, apps related to populations impacted by natural disasters or current events, and a selection of models and features to solve the world’s most-critical problems.
Join us for this 60-minute webinar by experts from ESRI Demographics and Living Atlas. You will learn about some of the exciting features available through Living Atlas specifically designed for users looking to upskill with demographic data by ESRI.
What is Arcade?
When I hear the word Arcade, I think of the days playing games like Pac-Man, Frogger, and Donkey Kong. However, this Arcade is used to customize ArcGIS apps.
ArcGIS Arcade was first developed to be a calculator. It allows you to compute values derived from attributes in a layer. The result can be used in popups, labels and in renderers. Also the Arcade scripts work throughout the ArcGIS system. In the latest versions of Arcade, you can use it to customize popup content and define conditional behavior in forms and dashboard elements based on user input.

The Most Important 18th-Century Map of California
If you have some cash to spend, like $600,000 to $800,000, you too could own this rare map of California! COSTANSÓ, MIGUEL DE. 1741-1814: Original Manuscript Map of Coastal California Signed (“Miguel de Costansó”).
Costansó was the engineer for the Portola Expedition, creating the first land based maps of the California coastline, and discovering and mapping the port of San Francisco for the first time. There are only 4 copies that still exist, and you can own one of them! Check it out, and good luck on your bid!
