How To: Determine which geocoding indexes go with which geocoding service

Summary

When a geocoding service is deleted, the index or indexes created are not removed automatically. Instructions provided describe how to determine which indexes coincide with which geocoding service.

Procedure

The naming structure of the geocoding and Alternate Names indexes are based on two parts. This allows for multiple geocoding indexes to be created for the same feature class.

The geocoding index is described in steps 1 and 2, while the Alternate Names index is described in steps 3 and 4.

Note:
This article only refers to geocoding in ArcGIS 9.1 and older.

  1. The first part of the geocoding index is based on the style of locator that was used to create the geocoding service. These are outlined below:

    Single Field				GC_KS
    US Alphanumeric Ranges GC_GR
    US Alphanumeric Ranges Zone GC_GRZ
    US Cities with State GC_CTS
    US Hyphenated Ranges GC_HY
    US Hyphenated Ranges Zone GC_HYZ
    US One Address GC_SS
    US One Address with Zone GC_SZS
    US One Range GC_SS
    US One Range with Zone GC_SZS
    US Streets GC_SS
    US Streets with Zone GC_SZS
    World Cities with Country GC_CTS

  2. The second part of the name is the derived from the ID of the feature class in the GDB_Objectclasses table.

    A geocoding index with the name SZS6 would mean that a geocoding style of 'US Streets with Zone' was used, and that the reference feature class had an ID value of 6 in the GDB_Objectclases table.
  3. Any geocoding service that has an alternate names table has an alternate Names index. This is named like the geocoding index described above but with a few minor differences.

    The first part of the alternate names index is based on the style of locator that was used to create the geocoding service. These are outlined below:

    US Alphanumeric Ranges (A)		GC_ALGR
    US Alphanumeric Ranges Zone(A) GC_ALGRZ
    US Hyphenated Ranges (A) GC_ALHY
    US Hyphenated Ranges Zone(A) GC_ALHYZ
    US One Address (A) GC_ALSS
    US One Address with Zone (A) GC_ALSZS
    US One Range (A) GC_ALSS
    US One Range with Zone (A) GC_ALSZS
    US Streets (A) GC_ALSS
    US Streets with Zone (A) GC_ALSZS

  4. The second part of the name is the derived from the ID of the alternate names table in the GDB_Objectclasses table.

    An alternate names index with the name ALSZS7 would mean that a geocoding style of 'US Streets with Zone' was used, and that the reference table had an ID value of 7 in the GDB_Objectclases table.
