Geocoding, also known as address search, is the process of converting text for an address or place to a complete address with a location. You can use the geocoding service to search for an address or a place, find candidate matches, and return complete addresses with a location.
With the service, you can build applications to:
To learn more about finding addresses and places, go to Geocoding.
How to access the geocoding serviceThere is no direct integration with CesiumJS to access the geocoding service. Instead, you use the geocoding and request packages from ArcGIS REST JS.
To access the service with ArcGIS REST JS, you typically perform the following steps:
If a library is not available to access a service, you can use the request library to define parameters and make requests to the service directly. This will require visiting the ArcGIS services reference to determine the required parameters.
Example Search for an addressThis example shows how to search for an address using the geocode operation from ArcGIS REST JS.
