Description
LAStools are a collection of highly-efficient, batch scriptable, multi-core command line tools for processing LiDAR that is built upon LASlib (with LASzip).
  • lasground.exe extracts the bare-earth by classifying all ground points
  • lasoverlap.exe checks overlap & vertical/horizontal alignment of flight lines
  • lascontrol.exe quality checks elevations for a list of control points
  • lasclassify.exe find buildings and the trees above the ground
  • lasgrid.exe rasters very large LAS files into elevation or intensity grids
  • lasboundary.exe extracts a boundary polygon that encloses the points
  • lasheight.exe computes for each point its height above the ground
  • lasclip.exe clips points against building footprints / swath boundaries
  • lastile.exe tiles huge amounts of LAS points into square tiles
  • laszip.exe compresses the LAS files in a completely lossless manner
  • lasinfo.exe prints out a quick overview of the contents of a LAS FILE
  • lasindex.exe creates a spatial index LAX file for fast spatial queries
  • txt2las.exe converts LIDAR data from ASCII text to binary LAS format
  • las2txt.exe turns LAS into human-readable and easy-to-parse ASCII
  • lasmerge.exe merges several LAS files into one
  • lassplit.exe splits points of one (or many) LAS files into flight lines
  • lassort.exe sorts points by gps_time, point_source, or into spatial proximity
  • las2las.exe extracts last returns, clips, subsamples, translate
