How do i get the elevation file (.dem file or any GM supported format) from the contour line in the given DGN? or How do I use contour lines directly to get the elevation at a given x,y position?

Is it possible to generate an elevation file using Global Mapper 11 in order to use it in SDK to get the elevation at a particular lat-lon or x,y position?

    In the SDK you can use the GM_GenerateElevationGrid function to calculate an elevation grid from any loaded layers with elevation values. In the Global Mapper application, just right-click on the DGN layer in the Control Center and select to create an elevation grid. Once that is done use File->Export Elevation Data to export to a new elevation file in whatever format you need.

    Thanks,
