is a tool that reads LIDAR points from LAS/LAZ/ASCII (or rasters from ASC/BIL/DTM format) and extracts a set of particular elevation contours in SHP/KML/WKT/TXT format. The user may specify to extract contours every 5 meters or only for individual elevation values. The contours can be smoothed or simplified on demand and hydro breaklines can be specified as well. For more details see the README file.
