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 was planned for a 50% acquisition overlap. The nominal resolution of this project
without overlap is 1.25m. 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 v1.0 format, classified according to ASPRS Class Code 2=Ground 1=Undefined. Water is included
in the bare earth ground model, except where the entire tile is covered by water.
The following regions of Connecticut are included in this project:
Fairfield County - 130 square kilometers
New Haven - 170 square kilometers
Middlesex - 29 square kilometers
New London - 157 square kilometers
Please note that the LiDAR intensity is not calibrated or normalized. The intensity value is meant to provide relative signal return strengths for features imaged by the
sensor.
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
