ESRI's Living Atlas of the World

The Living Atlas of the World is a curated collection that has been compiled by ESRI to share authoritative maps, apps, and geospatial data for use in the ArcGIS ecosystem.  Users can add Living Atlas data layers to ArcMap, ArcGIS Pro, and ArcGIS Online projects without the need to download or manage source data.  The layers are updated regularly, allow the user to custom symbology and configure pop-up windows.  The list below introduces several invaluable data layers but users should visit the homepage or search the ArcGIS Online Blog for posts about this valuable resource.

  • Census Data
