OpenTopography Tool Registry

The OpenTopography Tool Registry provides a community populated clearinghouse of software, utilities, and tools oriented towards high-resolution topography data (e.g. collected with lidar technology) handling, processing, and analysis. Tools registered below range from source code to full-featured software applications. We welcome contributions to the registry via the Contribute a Tool page.

Appearance of a tool in the OpenTopography Tool Registry does not imply endorsement, recommendation, or support, by the NSF OpenTopography Facility and is meant simply as a service to our users. OpenTopography does not guarantee the completeness or accessibility of specific content and links contributed by users. If you have been directly involved with the development of a registered tool and are not the original contributor of the tool to the registry, please email to supply updates or modifications to its entry.

6 May 2012 LAStools

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
  • Software Suite filtering, clipping, reprojecting, compression, classification, DSM, DTM, TIN, contours, bare-earth
