Description
Airborne LiDAR Filtering Method Based on Cloth Simulation.
Description
Cloth Simulation Filter (CSF) is an airborne LiDAR (Light Detection and Ranging) ground points filtering algorithm which is based on cloth simulation. It tries to simulate the interactions between the cloth nodes and the corresponding LiDAR points, the locations of the cloth nodes can be determined to generate an approximation of the ground surface <https://www.mdpi.com/2072-4292/8/6/501/htm>.
README.md
R package that wraps the CSF algorithm for Airborne LiDAR ground filtering based on Cloth Simulation. It is made to work along with the lidR package.
Example using lidR
library(lidR)
file <- system.file("extdata", "Topography.laz", package="lidR")
las <- readLAS(file, select = "xyz")
las <- lasground(las, csf())
plot(las, color = "Classification")
