Geiger-mode LIDAR Performance Under Canopy
With the advent of Geiger-mode LiDAR in the commercial arena, the idiosyncrasies of collection and processing methodology remain unknown to many in the community. This presentation will explain, in technical detail, how Geiger-mode LiDAR sensors can successfully image under canopy and provide high-quality 3D data. Multi-look collection methodology and system-specific parameters such as probability of detection (PDET) will be covered along with their impacts on data quality in complex environments. Effects of number of detections (NDET) will be shown to communicate how data quality changes as a function of sensor collection time. This phenomenon will be contrasted with how data quality changes as a function of dwell time with traditional linear-mode systems.
