GM_GenerateElevationGrid |
Generates an elevation grid and optionally a 3D area TIN layer from loaded 3D vector data. The layer handle(s) returned in aGridLayer and (optionally) aTinLayer must be closed with GM_CloseLayer when you are done with them.
See the definition of the GM_GridGenSetup_t type in the GlobalMapperInterface.h header file for a description of what options are available when generating the elevation grid. The default options are all a value of zero, or you can just pass NULL for the aGridSetup parameter to get the default options.
