GeoStan incorporates point data that locates addresses at the center of the actual building footprint or parcel.

Group 1 Software, Inc., a Pitney Bowes company, introduced a point-level solution that incorporates point data that locates addresses at the center of the actual building footprint or parcel. The GeoStan Point-Level Option provides enhanced geocoding accuracy with spatially enabled data for Internet mapping, flood hazard determination, property and casualty insurance, telecommunications and the utility industries. Group 1 introduced GeoStan Point-Level Option at the ESRI Worldwide User Conference, being held through July 29, 2005 in San Diego, California (Group 1 booth #1301).

GeoStan is an application program interface that corrects, standardizes and geocodes address information. GeoStan provides a comprehensive set of address-level geocodes by combining USPS® postal data with spatial data files from leading data providers, including Tele Atlas, into a single unified data set. Enhanced by Tele Atlas data, the GeoStan Point-Level Option can locate millions of addresses at the building or parcel center point.

Historically, geocoding was first performed at the ZIP code level, then ZIP +4, and more recently at the street segment level. With each evolutionary step, geocoding accuracy improved dramatically. With GeoStan™ Point-Level Option, positional accuracy is further enhanced. By providing the ability to locate an address at the center of a building or parcel, geocoding precision is improved by over 1000 feet in some cases.
