# Offline Maps

Every 24 hours, the Field Service mobile app evaluates whether your offline map covers the locations for a mobile worker's upcoming service appointments. If the app detects that the map area is insufficient for the next 24 hours of work, it prompts them to replace the current map with a new one that includes the relevant area.

Note Mobile workers can also manually download or refresh their map area at any time.

## How Map Data Stays Current

What mobile workers see on the map depends on whether they're online or offline and where the data comes from. A record that mobile workers create or update themselves always appears on their map, in either mode.

Online, mobile workers always see the most current data. The map refreshes each time they open it, and they can refresh it manually by pulling down.

Offline, whether mobile workers see other users' changes depends on the data source.

Salesforce data

Other users' changes appear only after a briefcase sync completes.

ArcGIS data

Other users' changes appear after a manual refresh or the automatic refresh that runs every 24 hours.

The 24-hour refresh interval is fixed and can't be shortened. To get the latest data sooner, mobile workers can refresh the map manually.
