[gdal-dev] FlatGeobuf Layer vs Feature Columns

2025-03-06 Thread Patrick Young via gdal-dev
Hello, I translated some geojson to flatgeobuf where the geojson features have a variable number of properties (e.g. some features have a bunch of translations for the name of a place pulled from OSM). I noticed in the ogrinfo output that while the summary info has all the fields possible, name:

[gdal-dev] Reading PMTiles With Missing Tiles

2024-02-22 Thread Patrick Young via gdal-dev
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: http
