2006 FEMA New Jersey Flood Mitigation Lidar: Middlesex County

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. The LiDAR flightlines for this project were planned for a 50% acquisition overlap. The nominal resolution of this project without overlap is 1.37m spacing, but effectively is 2.74m with overlap factored. Four returns were recorded for each pulse in addition to an intensity value. GPS Week Time, Flightline number and scan angle attributes were provided for each LiDAR point. Data is provided as random points, in LAS v1.0 format, classified according to ASPRS Class Code 1= Undefined, 2=Ground.
