Geospatial Analysis of Lambeau Field Using LIDAR Imagery Christopher Chapman University of North Alabama Geography Department LIDAR imagery of the above AOI is flown and data is processed (below) via LIDAR instrumentation. (L) 3D LIDAR image of Lambeau Field and parking lot that shows elevation. Blocks near stadium and in lot are cars and light poles. (B)Leo Frigo Memorial Bridge. (added for admiration) 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.
