LAStools is a collection of efficient, scriptable C++ command-line tools for processing LiDAR point cloud data in ASPRS LAS and compressed LAZ formats. It includes the open-source LASlib processing API and LASzip compression library, plus free and licensed tools for converting, merging, indexing, and analyzing point clouds.

Use cases

• compress large LAS LiDAR files to smaller LAZ files
• convert LiDAR point clouds between LAS, LAZ, ASCII, E57, and Shapefile formats
• merge or clip multiple LAS/LAZ files into one
• create spatial indexes for fast point cloud queries
• validate LAS files against ASPRS specifications
• inspect and compare LiDAR file contents
• rasterize point clouds into DEMs or extract contours
• classify buildings and vegetation in point clouds

When to choose

• you need fast, batch-scriptable processing of LAS/LAZ LiDAR data
• you want lossless compression of large point cloud files
• you work with geospatial point clouds in a command-line or GIS pipeline
• you need format conversion between LiDAR and ASCII/E57/Shapefile formats

When to avoid

• you need a GUI-first point cloud editor
• you require fully open-source versions of advanced tools like las2dem or lasclassify, which are closed source
• you work with non-LiDAR 3D formats like PLY or OBJ
