University of Maryland College Park

UMD Enterprise GIS — ArcGIS REST Services

The university's own ArcGIS Enterprise deployment — ArcGIS Server 12.1.0 and Portal 2026.1 at gis.umd.edu — and the machine-readable backend behind the official campus map at maps.umd.edu. The service catalog root, the server info document and the portal REST endpoint all answer keyless JSON; the fourteen service folders beneath them (Navigation, Utilities, UtilityNetworks, InteriorSpace, PlanningAndConstruction, AssetInventories, SnowCommandPortal, DIT, ESSR, OEMBC, POC, Layers, Print, UtilitySystems) return HTTP 200 carrying an ArcGIS error 499 "Token Required", so the catalog is public and the data is not. Esri wrote the software; the deployment, the host and the campus data are UMD's. Not previously catalogued anywhere in this profile.
