R package that wraps the MCC algorithm for Airborne LiDAR ground filtering based on Multiscale Curvature Classification. It is made to work along with the lidR package.
library(lidR)
<- system.file("extdata", "Topography.laz", package="lidR")
file <- readLAS(file, select = "xyz")
las <- classify_ground(las, mcc())
las
plot(las, color = "Classification")
