This paper describes the methodology adopted for developing a simulator for airborne altimetric LiDAR. The goal is to model LiDAR sensor functioning so LiDAR data can be generated for a user specified...
GOING UNDERCOVER: MAPPING WOODLAND UNDERSTOREY FROM LEAF-ON AND LEAF-OFF LIDAR DATA
laser scanning LiDAR woodland understorey overstorey broadleaf
2015/11/10
An understorey model is created for an area of broadleaf, deciduous woodland in eastern England using airborne LiDAR data from winter 2003 (leaf-off conditions) and summer 2005 (leaf-on). The woodland...
REGISTRATION OF AGIA SANMARINA LIDAR DATA USING SURFACE ELEMENTS
Terrestrial LIDAR Building Point Cloud Registration Algorithms Automation Performance
2015/11/10
Several approaches for automatic registration of terrestrial LIDAR data exist. However, they normally can not be compared to each other because of a lack of reference data. This is especially true for...
PROCESSING FULL-WAVEFORM LIDAR DATA:MODELLING RAW SIGNALS
lidar waveform analysis signal processing modelling generalized Gaussian
2015/11/10
Unlike airborne multi-echo laser scanner systems, full-waveform systems are able to digitize and record the entire backscattered signal of each laser pulse. It has been demonstrated that decomposing t...
