Segment IDs
Segment IDs are numeric codes that uniquely identify each point or street centroid candidate. The
MapMarker USA 25 geocoder returns the Segment ID for each S8, S7, S6, S5 and S4 candidate
(providing that the segment ID information is available in the Address dictionary.
L
Segment IDs are available with the Developer (Server) product only (not with the Desktop
application).
Wide Search
You can increase the probability of a match by using Relaxed mode in combination with wide search.
Wide search considers all streets that begin with the first letter of the input street name, and
therefore can identify more potential candidates.
Wide search is supported at both the API level and in the Desktop application. You can set wide
search in the
Match Settings dialog on page 249
and the

feature.
Centerline Offset for Point Candidates
If a point candidate is returned from a point dictionary, you can return the coordinates at a specified
offset from the associated street segment (rather than at the original point). This feature is available
if you are using a point-based Address Dictionary (such as Centrus Points or TomTom Points). See
for an overview of the available Address Dictionaries.
Centerline offset can be specified in feet, miles, meters, kilometers, and other supported units. The
default setting is 25 feet for USA and 7 meters for other countries. A centerline offset candidate has
an SC result code rather than an S8 (for example: SCHPNTSCZA). The C indicates that the point
has been moved a specified distance along the centerline.
The centerline offset capability is disabled by default, but you can enable and control it through the
Offset Preferences dialog. See
.
Expanded Search
MapMarker USA implements expanded search, which allows MapMarker to search for an address
within a given radius of the input address. Expanded search helps to find a match when the input
address contains limited or inaccurate city or ZIP Code information.
Expanded search is not implemented by default, but is supported at both the API level and in the
Desktop application. You can set expanded search in the
Match Settings dialog on page 249
and
the
Quick Find Settings dialog on page 261
.
