Hi, why is units=km not working?
gdaltransform -s_srs EPSG:4326 -t_srs "+proj=stere +lat_0=90 +lon_0=0 +lat_ts=60 +a=6378.14 +b=6356.75 +x_0=0 +y_0=0 +units=km" The following error is returned: ERROR 1: PROJ: proj_create_operations: Source and target ellipsoid do not belong to the same celestial body Converting +a and +b to meters and it does works: gdaltransform -s_srs EPSG:4326 -t_srs "+proj=stere +lat_0=90 +lon_0=0 +lat_ts=60 +a=6378140 +b=6356750 +x_0=0 +y_0=0" Any ideas? Wilco
