How to geocode a single address in Python Script/ ModelBuilder?

Question

How to geocode a single address (not table of addresses) in ModelBuilder and/or python Script? I want to enter the address and then geocode it. I am using arcgis 10.2.2

Answer 1

The geopy module is quick and easy for tasks such as this. Straight from the docs:

>>> from geopy.geocoders import Nominatim
>>> geolocator = Nominatim()
>>> location = geolocator.geocode("175 5th Avenue NYC")
>>> print(location.address)
Flatiron Building, 175, 5th Avenue, Flatiron, New York, NYC, New York, ...
>>> print(location.latitude, location.longitude)
(40.7410861, -73.9896297241625)
>>> print(location.raw)
{u'place_id': u'9167009604', u'type': u'attraction', ...}

Note that it includes classes to use just about any geocoding service that is out there.

I wrote a quick little function to do this with the ESRI python libraries You can grab it at: https://community.esri.com/groups/arcgis-python-api/blog/2018/12/28/single-address-geocode-with-python or just check out the code below

import requests
geoCodeUrl = "https://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer/findAddressCandidates"


def singleAdressGeocode(address, geoCodeUrl, outSR = "4326"):
  #clean up the address for url encoding
  address = address.replace(" ", "+")
  address = address.replace(",", "%3B")

  #send address to geocode service
  lookup = requests.get(geoCodeUrl + "?SingleLine=" + address + "&outSR=" + outSR + "&maxLocations=1&f=pjson")
  data = lookup.json()

  if data["candidates"]:
    #woo hoo results
    coords = data["candidates"][0]["location"]
    return coords
  else:
    #no results
    return "Address not geocoded: " + address

print singleAdressGeocode("1600 Pennsylvania Ave NW, Washington, DC 20500", geoCodeUrl)
