Enabling Location Services

The operating system will ask you to grant Global Mapper Mobile permission to access location data the first time you enable this feature. Global Mapper Mobile uses location data for live position display and the creation of vector features only. It is not transmitted or saved in any other way.

If Location Services are not currently enabled, you can enable them in the system settings, by going to Global Mapper Mobile application settings in the application list at the bottom of the main settings page. Global Mapper Mobile will still work and open map data if location services are disabled, but you will be unable to use tools that require GPS location and may receive some GPS error messages.

Your mobile device uses a technology called Assisted GPS. When you first enable a tool that uses GPS, the device will use local WiFi hotspots or cell towers (if the device is equipped with a cellular option) to get an immediate estimation of your location. If your device is equipped with GPS hardware (comes with the cellular option), it will then attempt to lock your position using actual global positioning satellites. This may take a few minutes. Thus, reported locations may be of low accuracy or may not work until a satellite lock is established.
