GM_ExportElevation |
Exports one or more layers to a new gridded elevation file. If NULL is passed for the layer handle, all elevation layers will be saved to the new elevation file, otherwise only the specified layer will be exported. If NULL is provided for the world bounds, all available data will be exported, otherwise only data within the specified bounds will be exported.
The new elevation file create will be in the current view projection as returned by the GM_GetProjection function. You can change the view projection, and thus the export projection, by calling the GM_SetProjection function.
