Comparison of full-waveform, single-photon sensitive, and discrete analog LIDAR data

Abstract

Full-waveform LiDAR data from an AHAB Chiroptera I system with 515 nm and 1032 nm lasers (∼10 pts/m 2 ), single-photon sensitive data from the Sigma Space HRQLS system with a 532 nm laser (∼19 pts/m 2 ), and discrete analog data from an Optech Orion C200 system (∼88 pts/m 2 ) were collected from aerial platforms over Monterey, CA, USA in fall 2012 and fall 2013. The study area contains residential neighborhoods, forested regions, inland lakes, and the Pacific Ocean near-shore environment. Significant ground truth in the form of GPS measurements and terrestrial LiDAR scans enable the LiDAR data to be compared in terms of measurement precision and degree of tree canopy penetration, as well as comparisons of derived raster products.

Evaluation of Single Photon and Geiger Mode Lidar for the 3D Elevation Program

“…There have been very few studies comparing the performance of these new sensors to LML or ground survey measurements [12,14], and this study is the first of its kind to evaluate the performance of LML to GML and SPL systems as they relate to collecting data that is adequate for the 3D Elevation Program. We evaluated both commercial instruments: the SPL HRQLS system by Sigma Space Corporation, and the Harris IntelliEarth™ GML.…”

Simulation and Design of Circular Scanning Airborne Geiger Mode Lidar for High-Resolution Topographic Mapping

“…Comparisons between LML, SPL, and GML were demonstrated in references [ 9 , 10 , 11 , 12 , 13 , 14 ]. The results showed that the measurement precision of SPL and GML is lower than that of LML on rough surfaces, and the measurement precision of these systems is the same on smooth surfaces [ 15 ].…”
