[gdal-dev] Usage of GDA_DATA in GDAL3

[Javier Jimenez Shaw]

Hi

When I was using GDAL2 (from C++), I had to set the GDAL_DATA variable with
something like
CPLSetConfigOption("GDAL_DATA", gdalDataPath.c_str());
to be able to use the SRS functions (using different coordinate reference
systems).

Now with GDAL3 (and PROJ7) I have to set instead the location of proj.db
with OSRSetPROJSearchPaths(...)

Do I need "GDAL_DATA" for anything else in GDAL3 ?

Thanks
