We have a bunch of legacy code that uses from osgeo import gdal, ogr, where
raster datasets are created with gdal and vector datasets with ogr. However,
these don’t mix well when, say, rasterizing a vector dataset with
gdal.rasterize. The ‘workaround’ is to create a vector dataset using gdal:
vector_ds = gdal.GetDriverByName("Memory").Create(“”, 0, 0, 0, gdal.GDT_Unknown)
But this is arcane and quite unintuitive.
Admitedly true, although the "recommended" way since the GDAL 2.0 GDAL and OGR
unification, at least on the C/C++ side of things.
The good news is that in GDAL 3.10 in Python bindings as well, ogr.DataSource
is just now an alias of gdal.Dataset, so you can use
ogr.GetDriverByName(...).CreateDataSource(...) as a valid gdal.Dataset
>>> from osgeo import ogr
>>> ds = ogr.GetDriverByName('Memory').CreateDataSource('')
>>> ds
<osgeo.gdal.Dataset; proxy of <Swig Object of type 'GDALDatasetShadow *' at
0x7fc32f3d9600> >
