Geocoding a Single Address Using World Geocoding Services

import arcpy

# Sign in to ArcGIS Online
username = "your_username"
password = "your_pwd"
arcpy.SignInToPortal("https://www.arcgis.com/", username, password)

# Create a new Locator object from the ArcGIS World Geocoding Service
locator_path = "https://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer/ArcGIS World Geocoding Service"
locator = arcpy.geocoding.Locator(locator_path)

# Geocode to find the location of an address
geocoding_candidates = locator.geocode("1670 W Peachtree St NE, Atlanta, GA 30309", False)
geocoding_candidates

Batch Geocoding Using the World Geocoding Services

import arcpy
arcpy.SignInToPortal("https://www.arcgis.com/", username='your_username', password='your_pwd')
arcpy.env.workspace = "C:/Users/Hugh/Desktop/geocoding"

# Set local variables
address_table = r"C:/Users/Hugh/Desktop/geocoding/Anchorage_addresses.csv"

# Using the World Geocoding Service for geocoding
address_locator = "https://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer/ArcGIS World Geocoding Service"

field_map = ("\'Address or Place\' Address VISIBLE NONE;Address2 <None> VISIBLE NONE;Address3 <None> VISIBLE NONE;" +
             "Neighborhood <None> VISIBLE NONE;City City VISIBLE NONE;Subregion <None> VISIBLE NONE;" +
             "Region <None> VISIBLE NONE;ZIP ZIP <None> VISIBLE NONE;ZIP4 <None> VISIBLE NONE;" +
             "Country Country VISIBLE NONE")

geocode_result = geocode_result.shp"

arcpy.GeocodeAddresses_geocoding(address_table, address_locator,
                                 address_fields, geocode_result,
                                 'STATIC')

Create a Locator object from a locator item on your own ArcGIS Enterprise Portal

import arcpy

# Sign in to your portal
username = "MyPortalUsername"
password = "MyPortalPassword"
arcpy.SignInToPortal("https://myenterpriseportal.esri.com/portal",username,password)

# Create a new Locator object from the locator on your portal
locator_path = "https://myenterpriseportal.esri.com/server/rest/services/Geocode/Atlanta/GeocodeServer/Atlanta"
locator = arcpy.geocoding.Locator(locator_path)

Geocoding with Geopandas

import pandas as pd
import geopandas as gpd
from shapely.geometry import Point

# Filepath
fp = "data/Helsinki/addresses.txt"

# Read the data
data = pd.read_csv(fp, sep=”;”)

len(data) data.head()

# Import the geocoding tool
from geopandas.tools import geocode

# Geocode addresses using Nominatim. # You can provide your own
geo = geocode(
data[“addr”], provider=”nominatim”, user_agent=”pythongis_book”, timeout=10)

geo.head()

join = geo.join(data)

join.head()

# Output file path outfp = “data/Helsinki/addresses.shp”

# Save to Shapefile join.to_file(outfp)

Geocoding with ArcGIS API for Python

from arcgis.gis import GIS
from arcgis.geocoding import geocode

gis = GIS()

geocoded_features = geocode(
    address=None,
    location=[-118.71511, 34.09042],
    category="Coffee shop",
    out_fields="Place_addr, PlaceName",
    max_locations=25,
    as_featureset=True,
)

geocoded_df = geocoded_features.sdf
geocoded_df.head(2)

m = gis.map()
m

m.center = [34.09042, -118.71511]
m.zoom = 11
m.draw(geocoded_features)
