RCSF

RCSF copied to clipboard

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  <- classify_ground(las, csf())

plot(las, color = "Classification")
