Description

lidR provides a set of tools to manipulate airborne LiDAR data in forestry contexts. The package works essentially with .las or .laz files. The toolbox includes algorithms for DSM, CHM, DTM, ABA, normalisation, tree detection, tree segmentation and other tools, as well as an engine to process wide LiDAR coverages split into many files.

Package options

lidR.progress

Several functions have a progress bar for long operations (but not all). Should lengthy operations show a progress bar? Default: TRUE

lidR.progress.delay

The progress bar appears only for long operations. After how many seconds of computation does the progress bar appear? Default: 2

lidR.verbose

Make the package verbose. Default: FALSE

lidR.buildVRT

The functions grid_* can write the rasters sequentially on the disk and load back a virtual raster mosaic (VRT) instead of the list of written files. Should a VRT be built? Default: TRUE

lidR.check.nested.parallelism

The catalog processing engine (catalog_apply) checks the parallel strategy chosen by the user and verify if C++ parallelization with OpenMP should be disabled to avoid nested parallel loops. Default: TRUE. If FALSE the catalog processing engine will not check for nested parallelism and will respect the settings of set_lidr_threads.
