    Hello,

    I am trying to import a .asc file from global mapper with a WGS84 UTM Coordinate system but I am stuck with it. It appears the next message on the screen (I attach the screenshot).

    Its confusing, because if I try to import the same file with "Esri Ascii Grid (Swiss local)" option, it works, but the terrain gets a wrong location.

    Greetings

    Hi Mario,

    It looks like you are using the UTM coordinate system which we are currently not supporting. You need to convert your coordinates into WGS84 format, until we have added UTM support. If I remember correctly, global mapper should support to store your file also in WGS84 format.

    If you want, you can also send us the file (send to contact@droneharmony.com) and we will look into converting it. It will also help us in adding UTM support.

    The header of the file should look something like this:
    ncols 429

    nrows 253
    xllcorner 14.953172767
    yllcorner 45.8581021305
    cellsize 0.0000089831528412
    nodata_value -9999.0


    Best regards,
