GIS Map Services and API User Guide

All of the ERS mapping applications, such as the Food Environment Atlas and the Food Access Research Atlas, use map services developed and hosted by ERS as the source for their map content. These map services are open and freely available for use outside of the ERS map applications. Developers can include ERS maps in applications through the use of the map service REST API, and desktop GIS users can use the maps by connecting to the map server directly. Over 30 ERS map services have been created, each containing anywhere from 4 to 70 map layers. The majority of the services consist of national maps displaying data at the county-level.
