Street Geocoder Tool

Geocoding associates geographic coordinates with input addresses, letting you pinpoint locations and carry out geography-based analyses. The Street Geocoder tool places a point object based on address interpolation by converting a multi-line address into a normalized form, with latitude and longitude, spatial object, and additional fields specific to the coding process. The full list of available fields is listed below.

The Street Geocoder tool requires a separate installation located on the Core Data Bundle installation Disk.

Even though the Street Geocoder tool performs a type of address standardization, the results are not CASS certified. If you require CASS certification, consider licensing Alteryx's CASS tool. Or use the Geocoder Suite US - This macro CASS certifies and Geocodes a number of different ways to ensure the best possible match.

Configure the tool

Select A Geocoder: Select a geocoder. All supported geocoders are selectable from this list.
Input Field Names: Select the appropriate field from your file for the following inputs:

Address: First line address typically contains the number and street.
City or Last Line: Last Line is used if you have a field that combines City, State and ZIP Code fields all in one field
State or Province: State or Province of the address.
Post Code: the ZIP Code or Postal Code field.

The Input Field Names are optional, but any missing fields or missing data within those fields have a negative impact on the score of the geocode.

When there is a multiple match: Specify how the geocoder should handle multiple matches. This setting only applies to geocoders that support multiple matches.
Prompt to select: Each time a Multiple Match is found, a dialog box provides options to handle the matches.
- First to all: Returns the first match with the highest Score for all matches found.
- None to all: Returns no selection for all matches found.
- OK: Select the appropriate match and click OK to accept. The selection registers for each match found.
- Cancel: Cancels the Geocoding process.
Return [None]: No match is returned. Reference the Match Status field which indicates whether a failed record has a multiple match.
Return 1st Candidate: The first match with the highest Score is returned.
Return All Candidates: All matches are returned. In the case of multiple matches, a record for each match is returned. Therefore the number of records inputted into the Geocoder may be a different number than the amount of records coming out of the Geocoder. Reference the Match Status field which will indicate whether a matched record had a multiple match.

Output Fields

Check the boxes next to the appropriate fields to append to the geocoded data table. Options on the right allow to Select All, Select Defaults, or to Clear All.

The output variables available depend on the geocoder product being used.

Third party geocoders will output similar variables.

Defaults

Field name	Description
MatchStatus	The type of match the record was assigned to; results can be: Exact: The geocoder found an exact match. It does not mean this match is an actual location. The exact match could be matching to a zip code for instance . Consult GeoLevel to see what the match. None: The geocoder could not find a geography to match the record to. Multiple: The geocoder found multiple match possibilities. When the geocoder comes to a record where it finds multiple possibilities to match the record to, a dialog displays asking the user to interactively select the appropriate match.
Score	A 1-100 value is appended based on the confidence of the match level. Score of 0.0 is returned for the Canadian Geocoder and Centroid Coder.
SpatialObj	The spatial (point) object to the assigned to the address record. This is the physical location of the geocoded address.
CensusID	Depending on the GeoLevel the record was geocoded to, the CensusID will go to that level of granularity. Census Block Code being the most granular level. CensusID is not returned from the Canadian Centroid coder.

Additional variables

Field name	Description
Latitude	The Latitude (Y) coordinate of the assigned point for the address record.
Longitude	The Longitude (X) coordinate of the assigned point for the address record.
FirstLine	The address # along with the street name are concatenated into a single field.
LastLine	The city, state and ZIP Code values are concatenated into a single field.
City	Assigns the City of the address record.
Province	Assigns the Province (State) of the address record.
PostalCode	Assigns the postal code (ZIP Code) of the address record.
GeoLevel	The geography level the record was geocoded to. In order of ideal match: Street: Address is assigned to its interpolated street location. Intersection: Address is assigned to the intersection of multiple streets. Extrapolate: When an input address is out of range, the Geocoder assigns the address to the closest known valid street segment. Main street has valid addresses in the range 1-100. The input address is 127 main street. Its not a valid address, but it would get assigned somewhere near 100 main street and the resulting GeoLevel==Extrapolate. Zip 5: Address is assigned to the ZIP Code centroid. When Geocoding a PO Box, a ZIP 5 centroid is the best match possible. The ZIP code that gets matched is, in most cases, the point location of the Post Office building. NULL: The input address failed to Geocode.
HouseNumber	Parses out the house number into its own field. In the case of an intersection, the first street nameâs house number will be listed here. 123 N King St returns 123
StreetPreDir	Parses out the street direction of the address when it appears at the beginning of the address before the geocode process (i.e. N, S, E, W). In the case of an intersection, the first streetnameâs pre direction will be listed here. 123 N King St returns N
Streetname	Parses out the street name of the address during the geocode process. In the case of an intersection, the first streetâs name will be listed here. 123 N King St returns King
StreetPostType	Parses out the street type of the address when it appears after the street name. In the case of an intersection, the first street nameâs post type will be listed here. 123 King St N returns St
StreetPostDir	Parses out the street direction of the address when it appears at the end of the address during the geocode process (i.e. N, S, E, W). In the case of an intersection, the first street nameâs post direction will be listed here. 123 King St N returns N
UnitDesignator	Parses out the Unit designator: BOX, #, BLDG, etc. 123 King St N, #2B returns #
UnitNumber	Parses out the Unit number following the designator. 123 King St N, #2B returns2B
StateAbbrev	Assigns the 2 or 3 character state/province abbreviation.
ClusterLevelID	Depending on the GeoLevel the record was geocoded to, the ClusterLevelID will go to that level of granularity. Census Block Code being the most granular level. In all US instances this is the same as the CensusID.
