> geohash calculation for points at given precision is very simple. For complex
> geometries there are several options:
> a. find a geohash where the whole shape fits, potentially decreasing precision
> b. calculate geohash for a given point (e.g. center of envelope) of the shape
> c. simply reject non-point geometries
> postgis does a. ([link|https://postgis.net/docs/ST_GeoHash.html]) while
> Apache Sedona does b.
