Example of getting geometry from a .shp 'shapefile'
# getStreets.py
# Example script that demonstrates how to get the geometry data out of a 'shapefile'
# A shapefile is a combination of .shp, .dbf, and .shx files, describing
# the (vector) shapes of geographic "features" (roads, bridges, lakes, etc)
# The following example deals with roads (in the Netherlands)
# (To make this script work, you'll have to download the shapefile for roads
# in the Netherlands and put these files in the same location as this file.)
