Description
GDAL 3 has changed the default order of coordinates to (latitude, longitude): https://gdal.org/tutorials/osr_api_tut.html#crs-and-axis-order
Consequently, geometry fields are saved in the spatial database as (latitude, longitude) whereas the expected order is (longitude, latitude).
Any geospatial calculation performed on a queryset also expects the coordinates to be in (longtiude, latitude), but as they are not saved in this format, the calculations results are incorrect and cause a variety of problems.
Extra support for GDAL 3 is required such that insert order of coordinates for saving geometry fields matches what the database expects.
Tested with django 3.0.7 against gdal 3.0.4, gdal 3.1.0, and gdal 2.4.3.
