Offline Maps
Download map tiles before you head somewhere without signal. Once downloaded, the map renders normally even with zero bars — and everything else in FieldOps keeps working because it syncs through other means or caches locally.
Why You Need This
FieldOps works where you work. Deep hollers, wildland fires, mountain SAR — cell signal is not guaranteed. Offline maps mean you keep the map visible, which is most of what matters. Pins you drop queue up and sync when signal comes back.
How to Download
- Open Settings → Offline Maps
- Tap + Download New Region
- Draw a box on the map around the area you need
- Pick which layers to download (Street, Satellite, Topo, or all)
- Pick max zoom level (higher = more detail = bigger file)
- Tap Start Download
How Big It Gets
Rule of thumb for a 10 × 10 mile area at reasonable detail:
- Street only — ~15 MB
- Topo only — ~40 MB
- Satellite only — ~80 MB
- All three — ~135 MB
Satellite is the heavy hitter. Skip it if you can work from topo + street.
Download tiles on WiFi before you head to the scene. Downloading a full county over cellular chews through your data plan and doesn't always complete reliably. Plan ahead.
How Long Tiles Last
Downloaded tiles stay on your phone until you delete them. Most base maps (streets, topo) don't change often. Satellite imagery gets refreshed annually by providers, so re-download once a year if currency matters.
