Hi, Have you tried -sql? Like -sql “select * from table where st_intersects(geom,reference_geom)”.

I can see how spatially filtering the input (-spat) is useful, but I don't want to clip the geometries (other than clipping by tile edges that MVT driver does by default). What I'm after is spatial filtering of the output tiles based on each tile extent. So to further clarify, I could do the translation using -spat <ROI> and then iterate over all of the generated MVT files and delete the ones whose tile extent does not intersect with <ROI>. But that would waste resources in a big way.

I'm prototyping with ogr2ogr but later I will be using Python bindings to create the production workflow. Is there a way to limit the geographic extent of where the MVT driver creates tiles? By default it seems to create all tiles that intersect any input feature. I would like to create only tiles that intersect a given extent. This is to enable partial update of a MVT tileset. This is the ogr2ogr command I have now: ogr2ogr -f MVT stand MV_R5232B.gpkg stand -dsco "MAXZOOM=11" -dsco "MINZOOM=8" -dsco "TILE_EXTENSION=mvt" -dsco "TILING_SCHEME=EPSG:3067,-548576,8388608,2097152" -dsco "TYPE=overlay" -dsco "COMPRESS=NO" Thanks, Jan Wolski _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org<mailto:gdal-dev@lists.osgeo.org> https://lists.osgeo.org/mailman/listinfo/gdal-dev -- http://www.spatialys.com<http://www.spatialys.com/> My software is free, but my time generally not.
