CSF (plugin)

Airborne LiDAR Data Filtering Algorithm Based on Cloth Simulation

Wuming Zhang, Jianbo Qi, Peng Wan, Hongtao Wang (School of Geography, Beijing Normal University, China)

Cloth Simulation Filter (CSF) is a tool to extract of ground points in discrete return LiDAR pointclouds.

If you use this tool for a scientific publication, please cite the following paper:

Zhang W, Qi J, Wan P, Wang H, Xie D, Wang X, Yan G. An Easy-to-Use Airborne LiDAR Data Filtering Method Based on Cloth Simulation. Remote Sensing. 2016; 8(6):501.

Command line mode

This plugin is a modified version of the CSF plugin that supports the command line mode. You can find more about it here

It supports every parameter of the CSF plugin, except the export mesh option.

Available options

Command Description
-CSF Runs the CSF plugin

Optional settings are:

  • -SCENES [scene]: name of the scene (SLOPE|RELIEF|FLAT)
  • -PROC_SLOPE: turn on slope post processing for disconnected terrain
  • -CLOTH_RESOLUTION [value]: double value of cloth resolution (ex 0.5)
  • -MAX_ITERATION [value]: integer value of max iterations (ex. 500)
  • CLASS_THRESHOLD [value]: double value of classification threshold (ex. 0.5)
  • -EXPORT_GROUND: exports the ground as a .bin file
  • -EXPORT_OFFGROUND: exports the off-ground as a .bin file
