[gdal-dev] warp issue: Source and target ellipsoid do not belong to the same celestial body

[Wilco K]

Hi,

these 2 lines work with GDAL 2.2.3, but not with GDAL 3.5.0 anymore.

gdal_translate -of GTiff -a_nodata 65535 -a_srs "+proj=stere +lat_0=90 +lon_0=0 +lat_ts=60 +a=6378.14 +b=6356.75 +x_0=0 y_0=0" -a_ullr 0.0, -3649.9792, 700.000, -4414.9792 "HDF5:\"RAD_NL25_RAC_03H_202401220800.h5\"://image1/image_data" "test-translate.tif"

gdalwarp -t_srs EPSG:4326 -dstnodata 65535 -of GTiff "test-translate.tif" "test-warp.tif"


Error:
ERROR 1: PROJ: proj_create_operations: Source and target ellipsoid do not belong to the same celestial body
ERROR 6: Cannot find coordinate operations from `PROJCRS["unknown",BASEGEOGCRS["unknown",DATUM["unknown",ELLIPSOID["unknown",6378.14,298.183263207102,LENGTHUNIT["metre",1,ID["EPSG",9001]]]],PRIMEM["Reference meridian",0,ANGLEUNIT["degree",0.0174532925199433,ID["EPSG",9122]]]],CONVERSION["Polar Stereographic (variant B)",METHOD["Polar Stereographic (variant B)",ID["EPSG",9829]],PARAMETER["Latitude of standard parallel",60,ANGLEUNIT["degree",0.0174532925199433],ID["EPSG",8832]],PARAMETER["Longitude of origin",0,ANGLEUNIT["degree",0.0174532925199433],ID["EPSG",8833]],PARAMETER["False easting",0,LENGTHUNIT["metre",1],ID["EPSG",8806]],PARAMETER["False northing",0,LENGTHUNIT["metre",1],ID["EPSG",8807]]],CS[Cartesian,2],AXIS["(E)",south,MERIDIAN[90,ANGLEUNIT["degree",0.0174532925199433,ID["EPSG",9122]]],ORDER[1],LENGTHUNIT["metre",1]],AXIS["(N)",south,MERIDIAN[180,ANGLEUNIT["degree",0.0174532925199433,ID["EPSG",9122]]],ORDER[2],LENGTHUNIT["metre",1]]]' to `EPSG:4326'


But when the +a and +b in the gdal_translate call are changed, gdalwarp does work:
gdal_translate -of GTiff -a_nodata 65535 -a_srs "+proj=stere +lat_0=90 +lon_0=0 +lat_ts=60 +a=6378140 +b=6356750 +x_0=0 +y_0=0" -a_ullr 0 -3649999.11191775 700000.903671186 -4415003.88199764 "HDF5:\"RAD_NL25_RAC_03H_202401220800.h5\"://image1/image_data" "test-translate.tif"

What is the problem?
