User Guide
An S8 georesult indicates that the address candidate is a point. No interpolation is required, so S8
result codes are returned regardless of whether address point interpolation is enabled.
Interpreting S7 Result Codes
S7 results are matched to an interpolated point along the candidate’s street segment. An S7 result
can return a complete 15-character Census Block ID. You must enable address point interpolation to
generate S7 result codes.
Both a point/parcel dictionary and a street segment dictionary must be available. An S7 candidate is
not located exactly at a known point. However, because both point and segment data is available,
the interpolation along the street segment can be very accurate.
The geocoded candidate location is interpolated based on the nearest point candidates on the street
segment. By using known address reference points on the street segment, the S7 interpolated point
can be more accurate than an S5 result.
Interpreting S6 Result Codes
An S6 code is returned from geocoding when the candidate is matched to a point ZIP centroid. A
point ZIP is a 5-digit ZIP Code that represents unique ZIPs such as a single site, building, or
organization. Point ZIPs do not cover an area, so they are shown as dots on a map rather than
polygons, and have no geographic extent defined in terms of street segments. Because these points
show actual locations, a different result code is used to distinguish them from other ZIP Centroid
matches.
Interpreting S5 Result Codes
S5 results are matched to an interpolated point along a street segment. This can return a complete
15-character Census Block ID.
An S5 result is based on a street segment dictionary only. This interpolation is not a accurate as an
S7 result, which can use point data to interpolate more accurately.
If you receive an S5 match for a record that was geocoded to an unexpected place, analyze the
result code to determine why. This situation can occur during a geocoding pass where you did not
require an exact match on house number, street name, and/or ZIP Code. When MapMarker
attempts to geocode the record with those settings, it searches larger areas than it would if the
conditions were stricter. Under those conditions, it is possible to match the record to a distant
address that has a similar name.
For example, a typical result might look like this: S5-P--S--A. The missing components in the result
code are represented by dashes. Even though MapMarker returned an S5 (it found a single match to
a street address), it did not match the house number (H), street name (N), street type (T), city (C), or
ZIP Code (Z). To minimize the matches that geocode to incorrect locations, geocode your table with
stricter matching conditions.
