Hi there,

For some reason when I try to load a projection file to convert my jpg to site datum, I get the above message and it will not reproject.

The strange thing is that I've used this projection file many times in the past without problem. See below and thanks in advance.

PROJCS["UTM_Zone_52_Southern_Hemisphere",GEOGCS["GCS_Geographic Coordinate System",DATUM["D_Estonia_1997",SPHEROID["GRS_1980",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Transverse_Mercator"],PARAMETER["latitude_of_origin",0],PARAMETER["central_meridian",129],PARAMETER["scale_factor",0.9996],PARAMETER["false_easting",500000],PARAMETER["false_northing",10000000],UNIT["Meter",1]]

    Actually this is the correct file:

    PROJCS["Local",GEOGCS["GCS_Geographic Coordinate System",DATUM["D_GDA94",SPHEROID["GRS_1980",6378137,298.257222101]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]],PROJECTION["Local"],PARAMETER["scale_factor",0.9996],PARAMETER["longitude_of_center",129],PARAMETER["latitude_of_center",0],PARAMETER["false_easting",468912.373],PARAMETER["false_northing",1324947.239],PARAMETER["azimuth",-28],UNIT["Meter",1]]

    I think your mistake is: PARAMETER["latitude_of_center",0], I think it should be "latitude_of_origin"
