Tutorial: Search for an address

Import modules and log in

1. Import the arcgis.gis module. This module is the entry point into the GIS and provides the functionality to manage GIS content, users, and groups. Additionally, import the geocode and reverse_geocode classes from the arcgis.geocoding module. Additionally, import the Point class from the arcgis.geometry module.

   from arcgis.geometry import Point
   from arcgis.geometry import Feature
   
   
   

2. Log into ArcGIS Online as an anonymous user. Simple geocoding and reverse geocoding do not require credits, hence you need not log in using your credentials.

Find an address

1. Search for an address by passing in the string "1000 Vin Scully Ave, Los Angeles, CA" as the address parameter of the geocode function. The geocode() function is versatile and accepts a number of relevant parameters. Refer to Finding points of interest to learn more.

Reverse geocode a coordinate

1. Construct a Point geometry object for the following latitude and longitude: 34.13419,-118.29636. The coordinates specified here are in latitude, longitude which correspond to the spatial reference GCS_WGS_1984. For a complete list of supported IDs and their corresponding definition strings, see: Spatial references.

   unknown_pt = Point(location)
   
   

2. Use the reverse_geocode function to find the address from a point location. Create a Feature from the returned dict and it to the geocoded_results FeatureSet.

Create a map

1. Create an instance of the map widget and set the initial extent by passing in a place name string of Los Angeles, CA.

   geocode_results.features.append(reverse_result_feature)
   geocode_results
   
   
   map = portal.map("Los Angeles, CA")
   map
   
   

Display the results.

1. Use the add method to display the results on the map. Since you specified the as_featureset=True optional parameter while geocoding, you received the result as a FeatureSet object instead of a dictionary. FeatureSet objects can be easily visualized on the map by passing to the add method.

   from arcgis.map.popups import PopupInfo
   map.content.add(geocode_results, popup_info=PopupInfo(title="{Addr_type}", description="Address: {LongLabel}"))

Try geocoding using the following addresses.

• Single line address: 380 New York St, Redlands, CA
• Administrative place name: New York City
• Zipcode: 66952

You should see the results of both the geocoded address and reverse geocoded point displayed as graphics on the map.
