Hi, This has been much improved in upcoming GDAL 3.10.0 : cf in particular https://github.com/OSGeo/gdal/blob/15589fea354e69f606af2a856828ecd506cb87b7/NEWS.md?plain=1#L538 . Now only the header and trailers of part-0 are read. That said duckdb will likely still outperform the OGR GeoParqu

Hello GDAL'ers , I have made a few attempts at using ogr2ogr for getting bounding box based extracts from overturemaps datasets. I am unfortunately not able to do so - something that takes duckdb or overturemaps-py 30s or less takes forever when

[gdal-dev] How to use JPEGXL in TIFF right?

2024-10-24 Thread Rahkonen Jukka via gdal-dev
Hi, I made some tests about using JPEGXL (JXL) compression in GeoTIFF. I am interested in lossless compression. So far I have learned that stripes are not good, but results from tiled TIFFs are promising. The GeoTIFF driver manual has a warning about WEBP compression: "There is a significant t

[gdal-dev] Is anyone using the JP2Lura driver?

2024-10-24 Thread Even Rouault via gdal-dev
Hi, I discovered yesterday that the JP2Lura driver (JPEG2000 support through proprietary LuraTech JPEG2000 SDK) had been totally broken during the whole GDAL 3.9 series (the identification function would fail to detect any JPEG2000 file). I've reached out to the initial proponents of the driv
