<p class="MsoNormal">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:<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">vector_ds = gdal.GetDriverByName("Memory").Create(“”, 0, 0, 0, gdal.GDT_Unknown)<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">But this is arcane and quite unintuitive. <o:p></o:p></p>

<p>Admitedly true, although the "recommended" way since the GDAL 2.0 GDAL and OGR unification, at least on the C/C++ side of things.<o:p></o:p></p>
<p>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<o:p></o:p></p>
<p style="margin-bottom:12.0pt">>>> from osgeo import ogr<br>
>>> ds = ogr.GetDriverByName('Memory').CreateDataSource('')<br>
