Assume you want to write EWKB/EWKT that includes SRID information (eg for inserting into Postgis). This is currently already supported, as you can do:
```
geoms = pygeos.points(...)
geoms_with_sr…

The spec does not state how to denote the entire world. None of the supported `geometry_types` suffice if the CRS is spheroidal and the edge type is spherical. With a planar edge type, a hacky, conven…

It would be great to have a parameterized parser object for speed. Things we could specialize on are:
- Endianness (little->big endian is just `bswap` on the result Float64 or Int)
- Geometry type:…

Hi,
If I have a Postgres/PostGIS DB containing tables with `geometry` columns of type `public.geometry(multilinestring, 27700)` I can attach it to my DuckDB database (with spatial extension already i…

OGC GeoPackage relies on WKB to encode geometry. The GeoPackage Vector Apollo file however seems to use EWKB, an extended version of WKB used by PostGIS and SpatiaLite.

Hi,
Lovely lirary but we are having an issue with MULTILINESTRINGs where it includes "EMPTY" in it similar to:

I've identified an opportunity for a massive speedup in cuspatial I/O using the WKB format. It'll also be more language/API agnost…
