Any news on this? I'm very interested in geometry columns in Arrow. Similar to [geopandas](https://github.com/geopandas/geopandas). ### [geopandas](https://github.com/geopandas/geopandas) and geometry serialization In [geopandas](https://github.com/geopandas/geopandas), C-pointers to [GEOS geometry](https://github.com/libgeos/geos/blob/8ae842b332c6d199ceeed7792a85b3d84a0baa45/capi/geos_c.h.in#L118) are stored in the "geometry column" as long integers (int64) wrapped in [shapely](https://github.com/Toblerity/Shapely) objects. The most compact way of persisting/serializing geometry in [GEOS](https://github.com/libgeos/geos), is as [WKB (Well-Known Binary)](https://en.wikipedia.org/wiki/Well-known_text_representation_of_geometry). I believe this is also how geometry is stored in [PostGIS](https://postgis.net/). ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
