| description | LIDAR (Light Detection and Ranging), being one of the latest optical remote sensing
technologies has gained increasing acceptance for topographic mapping due to its high
degree of precision and minimum human dependence. DSO (Defense Science
Organization) National Laboratories in Defense Ministry of Singapore is showing great
interests in further exploring LIDAR technology and its potential applications probably
in the area of surveillance and warfare. In this project, we researched into LIDAR
format information, its commercial/free software available and develop tools for
LIDAR data conversion and visualization which will facilitate the feature extraction
process in the later stage. Based on our research, it is clear that LAS (Log ASCII
Standard) File has become the standard format for LIDAR data. Despite LAS format
has several advantages, it is not human readable codes and commercial supporting
software for LAS are expensive. In order to push development of open source code
infrastructure and facilitate people who interested in LIDAR area to participate, we
have developed a LAS2TXT converter using MATLAB that allows users to convert
machine-readable LAS file into a human-readable TXT file which supports by many
free plotting software. In addition, we also devised a visualization tool using MATLAB
which could generate image similar to DEM (digital elevation model) file for
fundamental feature extraction. |
