Geocode Service

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 GeocodeServer resource represents a geocode (locator) service and provides basic information associated with the geocode service, such as the service description, address fields, spatial reference, and locator properties. The GeocodeServer resource supports the following operations:

OperationDetails
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.

Suggest

Returns a list of autocomplete suggestions for an input text string. Added at 10.3.
