LIDAR data is remotely sensed high-resolution elevation data collected by an airborne collection platform. By positioning laser range
finding with the use of 1 second GPS with 100hz inertial measurement unit corrections, Terrapoint's LIDAR instruments are able to make
highly detailed geospatial elevation products of the ground, man-made structures and vegetation. These data were collected from
March 29 - April 6, 2007 for Gloucester County, New Jersey. The project area covers 353 square miles. The LiDAR flightlines for this
project were planned for a 50% acquisition overlap. The nominal resolution of this project without overlap is 1.25 m. Four returns were
recorded for each pulse in addition to an intensity value. GPS Week Time, Intensity, Flightline and number attributes were provided for
each LiDAR point. Data is provided as random points, in LAS v1.1 format, classified according to the following ASPRS Class Codes:
Class 1 - Non-ground
Class 2 - Ground
Class 7 - Noise
Class 9 - Water
