The following table provides 'S' precision code descriptions for the
USA.
| Precision Code | Description |
|---|---|
| Street level geocoded candidates return a Precision Code beginning with the letter S. The second character in the code indicates the positional accuracy of the resulting point for the geocoded record. | |
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. |
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. |
S6 |
Single match, point located at point ZIP centroid. Note: The
point ZIP centroid is the ZIPcode location, not a polygon
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. |
S4 |
Single match, point located at a street centroid. |
S3 |
Single match, point located at ZIP + 4®. This is the same
quality match as a Z3 result. |
S2 |
Single match, point located at ZIP + 2 centroid. single
match, point located at ZIP + 2 centroid. This is the same
quality match as a Z2 result. |
S1 |
Single match, point located at ZIP Code centroid. This is the
same quality match as a Z1 result. |
S0 |
Single match, however, no coordinates are available (this is a very rare occurrence). |
SX |
Single match, point located at street intersection. |
SC |
Single 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 geocoding dataset and a street segment geocoding dataset are available and when the centerline offset feature is used. |
