| # Attempt at a shim for Shapely to work with basemap. | |
| # This is to try to use Shapely for the code that need libgeos. | |
| # The code is minimal on purpose. | |
| # add this file into the lib/mpl_toolkits/basemap folder | |
| # in __init__.py change this line: | |
| # import _geoslib | |
| # to: | |
| # import geosshim as _geoslib | |
| from shapely.geometry.base import BaseGeometry as ShapelyBaseGeometry | |
| import shapely.geometry | |
| import numpy | |
| class BaseGeometry(ShapelyBaseGeometry): | |
| # make shapely property a function | |
| def is_valid(self): | |
| return self.is_valid | |
| def fix(self): | |
| pass | |
| # not working quite right for basemap | |
| @property | |
| def boundary(self): | |
| return numpy.array(ShapelyBaseGeometry.boundary) | |
| class Point(BaseGeometry, shapely.geometry.Point): | |
| pass | |
| class LineString(BaseGeometry, shapely.geometry.LineString): | |
