In that case you need to create it manually. There's an example here, using
Python, but the API is pretty similar:

Remember to close it by duplicating the first vertex.
To get the footprint itself, you'll need to lo

Hi Mats,
Vector and raster datasets are pretty much different things in GDAL. And
generally it would be a good idea to check whether e.g. GetLayer actually
returns a pointer or nullptr.
What exactly do you mean by "associated OGRPolygon"? Do you want a polygon with
the same footprint as the ra
Hello,
Is there a way to get the OGRGeometry object out of a GDALDataset object in
c++?
My GDALDataset is a raster and i would like to get the associated
OGRPolygon out of it.
I've used:
srcDataset->GetLayer(0)->GetNextFeature()->GetGeometryRef()->toPolygon()
However i keep getting segmentation fau
