Folks, The GDAL driver code would need to be licensed the same as the rest of GDAL (which I see from the PR is the case). It is fine for the Grok library to be under the AGPL as long as it is an optional dependency of GDAL. Folks who are prepared to comply with it's license can enable it at buil

Aaron, benchnmarking exercices are difficult in general, and even more with JPEG2000 and its trillions of possible variants. You would need to specify library versions, how the library was exercised exactly (gdal_translate or the XXX_decompress utilities of the library), use of multithreading,

Please use GEOSNormalize / ST_Normalize or other equivalents before comparing geometries between library versions. The starting point in the ring can change because of different optimizations, and GEOS 3.9 was a complete rewrite of the geometry overlay subsystem. On Sat, Feb 27, 2021 at 9:02 PM Ka

Hi, OK, I've found something here: https://info.crunchydata.com/blog/waiting-for-postgis-3.1-geos-3.9 pointing out that a rewrite of the overlay engine in GEOS has taken place. But I couldn't find anything describing the behaviour of how the first point of the intersection is determined. It l

Hi, this might be a silly problem or no problem at all, but I currently can't wrap my head around it. I'm using python bindings of GDAL OGR with GEOS support for layer intersection since several years now. Now suddenly my testsuit which checks intersection of two boxes breaks since the inter
