Connect to Connecticut's Elevation Layers

 

The elevation data is served as a map service using Esri's ArcGIS Server. Click here to learn more about how we are doing it. The map services can be connected to in a variety of ways using the REST links at the bottom of the page.

Connect with ArcGIS Online

ArcGIS Online is a website by Esri that provides a platform for using, creating, and sharing maps, apps, and data, and accessing authoritative basemaps. CT ECO uses ArcGIS online to share many of Connecticut's maps and make it possible for users to save and make changes to the maps. In order to save, you must have an ArcGIS Online account. If you don't have an organizational account (these cost money, or come with a paid version of ArcGIS), you can create a free, public account (with restrictions and limited functionality) for exploring the ArcGIS Online.
