Single Match (S category)
Matches in the S category indicate that the record was matched to a single address candidate. The
first character (S) reflects that MapMarker found a street address that matches your record.
Within this category, a number of precision levels have been defined. The precision affects the
location of the geocoded point on the map. An address matched to a street address position has
greater positional accuracy than one matched to a ZIP Code™ centroid.
Matches in the S category can have the following types of precision:
•
Address point – Using address point interpolation, an address location is estimated based on a
street segment and the known address ranges and address points along that segment. Address
point interpolation places geocoded points more accurately along the street segment and can
prevent the “bunching” of points that can occur at either end of a street segment. See
Interpreting S7 Result Codes on page 130
for a description of S7 results returned by address
point interpolation.
•
Street – Address is matched to a street address position.
•
ZIP– Address is matched to a ZIP Code centroid or point ZIP centroid position.
Each of the S codes is defined below. The second position in the code reflects the positional
accuracy of the resulting point for the geocoded record, as indicated below.
•
S1 – single match, point located at ZIP Code centroid. This is the same quality match as a Z1
result.
•
S2 – single match, point located at ZIP + 2 centroid. This is the same quality match as a Z2
result.
•
S3 – single match, point located at ZIP + 4
®
. This is the same quality match as a Z3 result.
•
S4 – single match, point located at a street centroid.
•
S5 – single match, point located at a street address position. Because only street segment data
is available, the interpolation is not as accurate as an S7 return. See also
•
S6 – single match, point located at point ZIP centroid. See also
. This is the same quality match as a Z6 result.
•
S7 – single match, located at an interpolated point along a street segment. Both a point/parcel
dictionary and a street segment dictionary must be available. Because known point data is
available, the S7 interpolation is more accurate than an S5 result. See
.
•
S8 – single match, point located at either the single point associated with an address point
candidate or at an address point candidate that shares the same house number. No interpolation
is required. See also
Interpreting S8 Result Codes on page 129
•
SX – single match, point located at street intersection.
•
S0 – single match, no coordinates available (very rare occurrence).
•
SC – Single close match where the original point has been moved a specified distance (usually
along a perpendicular line) toward or away from the associated street segment. This result code
can be returned only when both a point/parcel dictionary and a street segment dictionary are
available and when the centerline offset feature is used.
