This week's Apache Sedona drop: lazy/selective GeoParquet reads in SedonaDB, @duckdb.org, GDAL, and GeoPandas! This is how querying a GeoParquet file plonked on a web server can be queried locally (and why GeoParquet can be even faster locally!) dewey.dunnington.ca/post/2025/la... #gischat
Lazy GeoParquet reading in SedonaDB, DuckDB, GeoPandas, and GDAL | Dewey Dunnington
I’m an obvious fan of GeoParquet and SedonaDB and it should be no surprise that I worked (still working!) pretty hard making sure SedonaDB could take advantage of all GeoParquet had to offer.
