I I found an example file that has `GEOGRAPHY` column and duckdb seems to be able to read it fine (though I note the column says "geometry" rather than "geography"): ```sql D select * from 'data/geospatial/crs-geography.parquet' limit 1; ┌──────────────────────┬────────────────────────────────────────────────────────────────────────────────────────────────────┐ │ wkt │ geography │ │ varchar │ geometry │ ├──────────────────────┼────────────────────────────────────────────────────────────────────────────────────────────────────┤ │ POLYGON ((-111 45,… │ POLYGON ((-111 45, -111 44.9, -111 44.8, -111 44.7, -111 44.6, -111 44.5, -111 44.4, -111 44.3, … │ └──────────────────────┴────────────────────────────────────────────────────────────────────────────────────────────────────┘ ``` https://github.com/apache/parquet-testing/tree/master/data/geospatial > > - `crs-geography.parquet`: Contains a GEOGRAPHY column with the crs > omitted. This should be interpreted as OGC:CRS84 (i.e., longitude/latitude). -- This is an automated message from the Apache Git Service.
