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.
If you don’t have a collection of data layers to provide, but still want to contribute, consider adding content through the Community Maps Editor app. Edit parts of the Esri Community Maps basemap to add detailed features for universities, schools, parks, landmarks, and other special areas of interest.
