Hello, I've been exploring the pmtiles driver a bit, what a great way to read giant blobs of tiles off of cloud storage, really impressed by how fast this is.
I've been encountering a "Non increasing tile_id" when attempting to read from coarser zoom levels for a large (~300GB) pmtile file: https://github.com/OSGeo/gdal/blob/48ddaf28db2826c635243abd469e7c7d2e749bdc/ogr/ogrsf_frmts/pmtiles/ogrpmtilestileiterator.cpp#L329 For example, this fails for me: ds = gdal.OpenEx("</vsis3/...", gdal.OF_VECTOR | gdal.OF_READONLY, open_options=["ZOOM_LEVEL=0"]) lyr = ds.GetLayer() for feat in lyr: *** raises RuntimeError: Non increasing tile_id *** Things seem good when I specify higher zooms (e.g. Z12 or not specified at all), but I can't get features out of the coarser ones. Using the "pmtiles tiles" command, I can access the 0/0/0 tile just fine though. Any thoughts on what could be wrong? The file was translated from a mbtiles file via the "pmtiles convert" tool. ogrinfo is happy with it as well: INFO: Open of `/vsis3/.../tileset.pmtiles' using driver `PMTiles' successful. Metadata: description=mvts for landcover layer format=pbf maxzoom=16 minzoom=0 name=mvts scheme=tms type=overlay version=2 ZOOM_LEVEL=16 1: landcover Thanks, Patrick
