Hi, Can I use lat/long coordinates directly when creating shapes with pyshapelib. I mean, for instance in the following sample program that uses pyshapelib (from : software.stablers.net/files/shapelibSample.py) could I use lat/long in the parameters of SHPObject def make_shapefile(filename):     obj = shapelib.SHPObject(shapelib.SHPT_POLYGON, 1,                              [[(10, 10), (20, 10), (20, 20), (10, 10)]])     print obj.extents()     print obj.vertices()     outfile = shapelib.create(filename, shapelib.SHPT_POLYGON) Do I need to specify anything so that ArMap interprets the coordinates correctly when importing the created shapefile? Thanks very much.
