Notes
This procedure generates a soundex key for a street name. Use it in conjunction with GSFFSEG when you want to perform a soundex search. The soundex key, when combined with a locale (state and city), is the primary index into the GeoStan databases. Searching by soundex allows you to use your own scoring and matching mechanism for geocoding.
GeoStan uses a modified version of the standard soundex algorithm first published by Donald Knuth. The modifications made by Precisely include special treatment of certain prefixes such as MAC, KN, and WR; special treatment for numeric street names; and an encoding scheme to pack the key into the smallest number of bits.
