Global Mapper v25.0

Exporting DTM Mesh and no elevation values


I have been trying to create a Mesh DTM but whenever l export it, the mesh has no elevation values. How do l go about it?


  • Can you add some more details about how you're trying to use the "mesh"?

    It sounds to me like you're trying to export a Raster DTM to something like a Triangulated Irregular network (TIN) DTM, to be used in CAD software?

    If that's the case.....

    Export Elevation Grid to "LandXML" file format

    (Optional) - Bring the LandXML file back in to GLobal Mapper and simplify it, then export it back out as a simplified version (CAD doesn't handle massive surfaces as well as GIS)


    After exporting to landxml, here is the same file after importing back in (TIN matches raster grid spacing that was exported)

    Simplify TIN
