Parameters ---------- ob : geometry The geometry to export to well-known binary (WKB) representation. hex : bool If true, export the WKB as a hexadecimal string. The default is to return a binary string/bytes object. srid : int Spatial reference system ID to include in the output. The default value means no SRID is included. **kw : kwargs, optional Keyword output options passed to :func:`~shapely.to_wkb`.
