Interface to (geo-)spacial analysis libraries

Dear all,

as far as I understand, the heavy (geo-)spacial computations are normally done in Python using Shapely, PySAL etc. and are not generally the aim of this library.

Given we’d like to perform such computations on SVG shapes (e.g. set operations, distances), is there any recommended way to export or interface Path primitives for external applications?

Hey, trimesh might be useful for this sort of thing, it’s using svg.path internally:

In [1]: import trimesh

In [2]: path = trimesh.load('wrench.svg')

In [3]: path
Out[3]: <trimesh.path.path.Path2D at 0x7f1d08c8dc50>

In [4]: path.polygons_full
Out[4]: 
array([<shapely.geometry.polygon.Polygon object at 0x7f1d08c53be0>],
      dtype=object)

It seems to me that using svg.path for parsing and then converting the SVG shapes to something that can be fed to Shapely should be quite easy.
