Popis

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 100 hz inertial measurement unit corrections; Terrapoint 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 was planned for a 50 percent 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 format, classified according to ASPRS Class Code 2=Ground 1=Undefined.
