r-lidar is developing free and open-source airborne laser processing software primarily designed for the R programming language. Our four main packages are the lidR, lasR and lidRalignment packages, each targeting different usages. We also provide professional paid services, including training courses, development, counseling, and R&D. See more details on our website r-lidar.com.

• lidR is tailored for research and development, originally developed at Laval University. It allows the handy manipulation of lidar data within the R programming language. It has been widely used for 10 years by universities globally and has been cited in more than 1,000 scientific articles.

• lidRalignment enables automatic alignment of forest plot point clouds from different sources, such as ALS with TLS or MLS, or TLS with MLS, or ALS with ALS in a unified pipeline.

• lasR is tailored for highly efficient airborne lidar data processing. It was designed to be much more powerful than lidR by allowing the creation of complex and optimized processing pipelines and applying them to terabytes of data efficiently. It allows to push ideas developped with lidR into production.

You can support the development by sponsoring us.

We also maintain other open-source projects for airborne lidar data processing in R:

• rlas: R package to read and write las and laz files used to store LiDAR data
• RMCC: Airborne LiDAR filtering method based on Multiscale Curvature Classification
• RCSF: Airborne LiDAR filtering method based on Cloth Simulation
• lidRviewer: R package to plot large point clouds.

r-lidar laboratory is another place where you can find experimental and maturing software, as well as R&D tools we designed.
