It is set during construction of driver managers of GDAL http://trac.osgeo.org/gdal/browser/trunk/gdal/gcore/gdaldrivermanager.cpp?rev=18770#L98 OGR http://trac.osgeo.org/gdal/browser/trunk/gdal/ogr/ogrsf_frmts/generic/ogrsfdriverregistrar.cpp?rev=18770#L67 What in practice means, during during first access to any of these two driver managers. This usually happens when a client calls either GDALAllRegister http://trac.osgeo.org/gdal/browser/trunk/gdal/frmts/gdalallregister.cpp?rev=18207#L73 or OGRRegisterAll http://trac.osgeo.org/gdal/browser/trunk/gdal/ogr/ogrsf_frmts/generic/ogrregisterall.cpp?rev=18449#L38 (GDAL_DATA is shared among GDAL and OGR) > After looking at the code and reviewing this > <http://lists.osgeo.org/pipermail/gdal-dev/2009-May/020584.html> > email thread, it appears that the environment variable is currently > only read at initialization time > (OGRSFDriverRegistrar::OGRSFDriverRegistrar() is one such place), and > that changes to the variable after initialization time will not be > recognized. Is that correct? AFAIU, yes. > Do you anticipate that that behavior will change in the future? I don't know.
