Hi, I just came across the .map format, a tiled vector format (see https://www.openandromaps.org/en/) I tried opening the files and failed, is there support for this in gdal/ogr? Thanks Matthias Previous question on the topic: https://www.openandromaps.org/en/oam-forums/topic/openandromaps-in-q

Thanks a lot for the help, Even. That just saved me some headache. I'll respectfully approach the source of this data before trying to figure out where to put tabs and line breaks and warping. And then crossing fingers that the national administration open sources the data in a usable format rath

[gdal-dev] Non-standard field types in OGR

Hi, I'm looking for a way to load a geopackage layer with a type affinity set to a custom type and to detect this type. I.e. what I have is a table with a field called myJson, the type of which is JSON. Looking at the debug output of QGIS, I currently get this message which seems to be generated

Hi, I have a question regarding creating raster data (geopackage). It's trivial to create files with gdal_translate if there is already an existing source raster file (e.g. geotiff). What I need to do is to download tiles and "feed" them to a geopackage raster file. I guess I could just download
