The Community Maps Program enables community contributions of authoritative data to help build the ArcGIS Living Atlas. You can provide feedback, create detailed features, and share data layers and services, contributing to Esri basemaps that anyone can use.
The Community Maps Editorlets you edit parts of the Esri Community Maps basemap to add detailed features for universities, schools, parks, landmarks, and other special areas of interest. The editor has been updated with new features and capabilities. For more information, see this blog article by @SethSarakaitisCommunity Maps editor updated.
