ArcGIS REST API - ArcGIS Services

URL:http://<catalog-url>/<serviceName>/GeocodeServer
Operations:Find Address Candidates,Reverse Geocode,Geocode Addresses
Version Introduced:9.3

Description

Geocoding is the process of assigning a location, usually in the form of coordinate values (points), to an address by comparing the descriptive location elements in the address to those present in the reference material. Addresses come in many forms, ranging from the common address format of a house number followed by the street name and succeeding information, to other location descriptions such as postal zone or census tract. An address includes any type of information that distinguishes a place.

The REST API Geocode Service resource represents a geocode (locator) service. This resource provides basic information associated with the geocode service, such as the service description, address fields, spatial reference, and locator properties.

The Geocode Service resource supports the following operations:

Find Address Candidates—Returns a list of candidates based on address and location.
Reverse Geocode—Returns information about all the address fields pertaining to the reverse geocoded address as well as its exact location.
Geocode Addresses—Performs batch geocoding. Added at 10.1.
