Read and Write 'las' and 'laz' Binary File Formats Used for Remote Sensing Data
Read and write 'las' and 'laz' binary file formats. The LAS file format is a public file format for the interchange of 3-dimensional point cloud data between data users. The LAS specifications are approved by the American Society for Photogrammetry and Remote Sensing <https://www.asprs.org/divisions-committees/lidar-division/laser-las-file-format-exchange-activities>. The LAZ file format is an open and lossless compression scheme for binary LAS format versions 1.0 to 1.3 <https://laszip.org/>.
Readme
R package to read and write .las and .laz binary files used to store LiDAR data.
rlas relies on a modified version of LASlib and LASzip that were modified to be compatible with R. The library can therefore be compiled into R without any complaints from R CMD check. It enables R users to read and write binary files commonly used to store LiDAR data. LAS version 1.0 to 1.4 are supported.
library(rlas)
lasdata <- read.las("<myfile.las>")
lasheader <- read.lasheader("<myfile.las>")
