Hello all, hope you are well

Got some unexpected results computing area using GDAL==3.4.1 and official
Brazilian projection, where results are about half of what is reported as
correct. Does anyone knows what is causing it ?

Just to compare shapely/geopandas yields correct results using same
projections.

code can be found on this gist:
https://gist.github.com/rupestre-campos/a82a1403cb47a8153f07c775d7902f50

the linked scrip outputs
Area ha farm: 6.0
Area ha calculated (gdal): 3.23
Area ha calculated (geopandas): 6.0
