Thin Python wrapper for the US Census Geocoder

Project description

Python 2 and 3 wrapper for the US Census Geocoder API.

Basic example:

from censusgeocode import CensusGeocode

cg = CensusGeocode()

cg.coordinates(x=-76, y=41)
cg.onelineaddress('1600 Pennsylvania Avenue, Washington, DC')
cg.address('1600 Pennsylvania Avenue', city='Washington', state='DC', zipcode='22052')

Use the returntype keyword to specify ‘locations’ or ‘geographies’. Geographies is the default.

cg.onelineaddress('1600 Pennsylvania Avenue, Washington, DC', returntype='locations')

Queries return a CensusResult object, which is basically a Python list with an extra ‘input’ property, which the Census returns to tell you how they interpreted your request.

>>> result = cg.coordinates(x=-76, y=41)

>>> result.input
{u'vintage': {u'vintageName': u'Current_Current', u'id': u'4', u'vintageDescription': u'Current Vintage - Current Benchmark', u'isDefault': True}, u'benchmark': {u'benchmarkName': u'Public_AR_Current', u'id': u'4', u'isDefault': False, u'benchmarkDescription': u'Public Address Ranges - Current Benchmark'}, u'location': {u'y': 41.0, u'x': -76.0}}

>>> result
