I have all the 30m Aster GDEM data for Namibia, and now would like to generate 20m contours, it would appear that Global Mapper 11 has some limitations, as it does not work?, can someone give some advise how do generate contour with a large DEM

    For contouring such a large area at once you will want to use the Gridding tab on the contour dialog to split the operation into a lot of smaller pieces and also check the option on the main contour options tab to export the results directly to Global Mapper Package files. This should export your generated contours directly to files rather than keeping them in memory, allowing much larger areas to be contoured.

    Let me know if I can be of further assistance.

    Thanks,
