示例1: map_poly_shp
# 需要导入模块: from matplotlib.collections import PolyCollection [as 别名]
# 或者: from matplotlib.collections.PolyCollection import shp2dbf_row [as 别名]
def map_poly_shp(shp, which='all', bbox=None):
'''
Create a map object from a polygon shape
...
Arguments
---------
shp : iterable
PySAL polygon iterable (e.g.
shape object from `ps.open` a poly shapefile) If it does
not contain the attribute `bbox`, it must be passed
separately in `bbox`.
which : str/list
List of booleans for which polygons of the shapefile to
be included (True) or excluded (False)
bbox : None/list
[Optional. Default=None] List with bounding box as in a
PySAL object. If nothing is passed, it tries to obtain
it as an attribute from `shp`.
Returns
-------
map : PatchCollection
Map object with the polygons from the shape
This includes the attribute `shp2dbf_row` with the
cardinality of every polygon to its row in the dbf
(zero-offset)
