Mapmarker 6.0 and questionable Geocoding results.
In geocoding the table below it is required to geocode records to an S3 or above hit rate, and anything below S3 to be coded to a Z3. All other records may
remain unmatched. When geocoding to street level, MapMarker outputs the zip and zip+4 back to the table as if it found the records, yet it will give them an S1 or S2 georesult code. Why would it do this if a Z3 is more accurate, and if MapMarker supposedly found the zip+4 record?
If Mapmarker outputs zip+4, why would it give only S2 or S1 georesults?
MapMarker Data is made from 2 sources: Tiger(the actual Points) and USPS (Street names, Zip codes and the like). When the MapMarker product is created, the two sources are combined but sometimes have a Zip and Zip+4 record with no point(object\coordinate location). This is why MapMarker will return the complete Zip+4 but only a match to Zip centroid or Zip+2 position.
Note: S3 and Z3 are the same accuracy.
