Provide the Destination CRS in the same way. There are many file sources and CRS definitions out there in the wild that but can not be picked until you install the required package One solution is to transform (ST_Transform) the polygon to another crs before calculating the area, perhaps the appropriate UTM32 zone, but that will require us to dynamically determine the zone first. while now you will see something like this: This gives a better user interface and integrates improvements from pyproj and As the size of a degree is variable depending on the location in the world, this does not make much sense. , accuracy 1.0 m, code 5585 (default) [3] Selected transformation Method: Geocentric translations (geog2D domain) Remarks: Parameter values from MOLDREF99 to ETRS89 (1) (code 5584).
