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.
