GeoParquet, an open format for geospatial vector data in #Apache Parquet, combining cloud-native analytics ⚡ with spatial metadata 📄, is becoming increasingly present in geospatial workflows ☁️🌍📊

The #OGC has published guidance for distributing #GeoParquet files, covering compression, spatial indexing & ordering, row group sizing, partitioning, and metadata.

It also includes practical commands for common tools to help generate optimized outputs ⚙️

So happy about my new activity #heatmap. Done with #DuckDB and #Geoparquet. No #AI and it was very satisfying after three weeks of learning to get it right for myself.

geoparquet-io: Fast #GeoParquet tool: geoparquet-io is an open-source #CLI tool and #Python library for converting, inspecting, optimizing, and partitioning #GeoParquet files, automatically applying GeoParquet performance best practices along the way. Its extract command can pull geodata from sources such as #WFS, #Esri ArcGIS Feature Services, or #BigQuery into GeoParquet.

Oh no, remote #GeoParquet is much less fun in #QGIS than I thought. These few polygons took ~50 Megabytes to fetch. I guess it is not enough to just use #GDAL defaults.

OSM data in GeoParquet format

There has been some discussion about OSM data in GeoParquet format, most recently in The last hurrah for OSM - #44 by SimonPoole. Apparently there many different ways to stuff OSM data into some form of Parquet; osm-parquetizer does it with raw data, ohsome-planet builds geometries even for historical data, and cadencemaps tries to emulate Overture’s POI schema. As the person running the Geofabrik download server I have been wondering if I could add some simple form of GeoParquet files to the d...
