LIDAR imagery of

the above AOI is

flown and data is

processed

(below) via LIDAR

instrumentation.

LIDAR (Light Detection and

Ranging) is a remote

sensing technology that

collects 3-dimensional point

clouds of the Earth’s

surface. LIDAR

instrumentation uses a laser

scanner with up to 400,000

pulses of light per second.

The laser transmits pulses

and records the time delay

between a light pulse

transmission and reception

to calculate elevation

values. These values are

integrated with information

from the aircraft’s Global

Positioning System (GPS)

and orientation (pitch, roll,

and yaw) data from inertial

measurement technology

to produce point cloud

data. Each data point is

recorded with precise

horizontal position, vertical

elevation, and other

attribute values.

Point cloud data represent the elevation of landscape features

including bare earth, trees and buildings. Topographic LIDAR instruments

use wavelengths in the near-infrared regions of the spectrum with a

Nominal Pulse Spacing (NPS) of 3 meters or finer.
