ArcGIS Urban API
A GraphQL API for ArcGIS Urban - urban models, plans, projects, branches, parcels, zones, spaces, building types, indicators, metrics, overlays, viewpoints and scenario analyses (elevation profile, line of sight, shadowcast, viewshed, suitability, sunlight). Anonymous introspection is open, so the full schema is machine-readable without a credential; executing queries requires an ArcGIS token.
