An overview of the Geocoding toolbox
(ArcGIS, ArcToolbox) Tools
· Geocoding is the
process of assigning a location, usually in the form of coordinate values, 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 house number followed by the street name and
succeeding information to other location descriptions such as postal zone or
census tract. In essence, an address includes any type of information that
distinguishes a place.
· Many common
tasks are related to the geocoding process, such as creating and maintaining
address locators, geocoding addresses, and getting addresses for point
locations. The Geocoding toolbox contains tools to assist in accomplishing
these tasks.
· Tools of the Geocoding toolbox:
1. Create
Address Locator
Creates an address locator. The address locator can be used to find a
location of an address, geocode a table of addresses, or get the address of a
point location.
2. Create
Composite Address Locator
Creates a composite address locator. A composite address locator consists
of two or more individual address locators that allow addresses to be matched
against the multiple address locators.
3. Geocode
Addresses
Geocodes a table of addresses. This process requires a table that stores
the addresses you want to geocode and an address locator or a composite address
locator. This tool matches the addresses against the address locator and saves
the result for each input record in a new point feature class. When using the
ArcGIS World Geocoding Service, this operation may consume credits.
4. Rebuild
Address Locator
Rebuilds an address locator to update the locator with the current
reference data. Since an address locator contains a snapshot of the reference
data when it was created, it will not geocode addresses against the updated
data when the geometry and attributes of the reference data are changed. To
geocode addresses against the current version of the reference data, the
address locator must be rebuilt if you want to update the changes in the
locator.
5. Rematch
Addresses
Rematches addresses in a geocoded feature class.
6. Reverse
Geocode
Creates addresses from point locations in a feature class. The reverse
geocoding process searches for the nearest address or intersection for the
point location based on the specified search distance. When using the ArcGIS
World Geocoding Service, this operation may consume credits.
7. Standardize
Addresses
Standardizes the address information in a table or feature class.
