GDAL Integration
GDAL Integration
The spatial extension integrates the GDAL translator library to read and write spatial data from a variety of geospatial vector file formats. See the documentation for the st_read table function for how to make use of this in practice. In order to spare users from having to setup and install additional dependencies on their system, the spatial extension bundles its own copy of the GDAL library. This also means that spatial's version of GDAL may not be the latest version available or provide support for all of the file formats that a system-wide GDAL installation otherwise would. Refer to the…

PostGIS spatial joins in DuckDB · Cloud-Native Geospatial · Geomermaids
PostGIS spatial joins in DuckDB · Cloud-Native Geospatial · Geomermaids
Translate the spatial joins you already write in PostGIS into DuckDB, query plan beside query plan, on the same FEMA data, and see where DuckDB's younger, less-integrated spatial layer makes you drive by hand.
Every example joins two tables: flood_zones, US-wide flood-hazard polygons published by FEMA, each with a flood risk score (0 = minimal, 25 = 0.2%-annual zone, 35 = 1%-annual zone) and reference_points, a small table of points we want to score (5 sitting inside real zones, 2 in open country). PostGIS holds ~5.9M polygons; the DuckDB copy is the same data subdivided into ~14.9M finer polygons, stored as a .ddb (~76 GB with its R-tree). Same data, fair fight.
