Importing and Exporting Data

Data for Global Mapper Mobile can be prepared in Global Mapper desktop, then exported to a Global Mapper Mobile Package file (*.GMMP) to be shared and used on a mobile device. With the Global Mapper Mobile Package file (*.GMMP) Pro Module registered, users can also import GeoPDF and GeoPackage files

Methods for transferring data from a computer to an iOS device, include: utilizing Global Mapper desktop's Mobile Data Management tool, connecting the device to the computer and using finder, emailing the file, and using file sharing apps (Google Drive, Dropbox, etc.). Shared Files can be opened with the Open Map option from the home screen or Main Menu.

Mobile devices are typically less powerful than the desktop or laptop machines used o run Global Mapper desktop. In particular, run-time memory available to applications is quite limited. The operating system will shut the application down if it consumes too much memory (approximately 100 MB on iOS).

It is recommended that you simplify data to be used in your mobile app as much as practical. This means possibly reducing the resolution of raster and grid layers. Large lidar data sets are simply not practical and it is recommended that you grid any large data for use in the mobile device. The app does not currently support Lidar data.
