Every service has data the public mapping providers don’t have. Hydrants for fire. ANPR cameras for police. Hospital diversion overlays for ambulance. Property risk records, vulnerable-persons flags, asset locations, training-area perimeters.
Custom data layers let you overlay any of it directly on the responder app’s maps. Push your data from GIS systems, ArcGIS feeds, CSV uploads, or spreadsheet edits. Layers update in real time and are available offline as cached snapshots.
Layer visibility is per-role: a fire crew sees hydrants and risk data by default; a police officer sees ANPR and restricted zones; an ambulance crew sees diversion overlays and A&E ETAs. Administrators control who sees what.
