Any help would be appreciate it.

    It looks like the Magna Sirgas datum for Columbia is basically coincident with WGS84 or the built-in Sirgas 2000 (Brazil) datum in Global Mapper, at least within a meter or so. I couldn't find a transformation either for sub-meter accuracy. Let me know if you find one and I can add this as a built-in datum in Global Mapper.

    Let me know if I can be of further assistance.

    Thanks,

    Geospo,

    The EPSG code 21892 is deprecated, you should use 21897 instead for the same projection. That one should work fine.

    Let me know if I can be of further assistance.
