To reproject a file in Global Mapper, perform the following steps:
- Load the file into Global Mapper
- Go to Configuration > Projection to set the display projection to the desired output projection. Jump to this setting by double-clicking on Current Workspace in the Control Center.
- Export the file using the File > Export menus, or by right-clicking on the layer in the Control Center and going to Layer > EXPORT
The data will be reprojected into the display projection during export. Note some file formats have a limitation on supported projections.
