Hi, I would like to use ogr2ogr for selecting all the features from the source layer that intersect with the reference layer but without computing the intersections. So fundamentally what the -spat option does but with more complicated geometries than BBOX. The -clipsrc option finds the right geometries but it also computes the intersections of the geometries and there is no way to avoid that. I guess that something should be changed around https://github.com/OSGeo/gdal/blob/master/apps/ogr2ogr_lib.cpp#L4879 where the stolen geometry is changed into the clipped geometry. I know I can use SQLite dialect by utilizing the ST_Intersects function but SQL with JOIN gets a bit complicated.
