Shapely linestring z empty
Webb24 dec. 2024 · Dimensionality of empty geometries is in general a bit a messy topic, and depending on shapely and GEOS versions. In the new implementation for writing WKT in shapely 2.0, at some point we added some special case code for empty 3D geometries ( pygeos/pygeos#403 ): shapely/src/geos.c Lines 307 to 369 in 9105bd3 Webb15 sep. 2024 · Left and right are determined by following the direction of the line.

The constructed LineString object represents one or more connected linear splines between the points. Repeated points in the ordered sequence are allowed, but may incur performance penalties and should be avoided.
