Global Positioning System

The NAVSTAR Global Positioning System (GPS) has become an accepted and widespread technology for capturing mappable features digitally for use in a GIS. The system is based on a constellation of orbiting satellites that enable users with GPS receivers to determine 3D positions anywhere on or near the earth's surface. NJDEP operates a Trimble Navigation Pathfinder Community Base Station in Trenton. This station stores GPS base data and the files are available through the link below.
