DataInit: Extract a slice of point cloud around DBH height for TreeMap

In EmmanuelDuchateau/TLS: Provides Tools For Terrestrial LiDAR Data Analysis

Description

Extract a slice centered on the DBH height (1.3m) with a thickness of 2* ThickDHP

Usage

DataInit(Mydata, ThickDHP = 0.1, Hsoil = 4)

Arguments

Mydata	this dataset should contain at least 3 columns with X, Y, Z values. The .las (.laz) format is better for faster processing but a data.frame (or data.table) is acceptable.
ThickDHP	indicate the thickness of the slice around the DBH (1.3m height) (10cm by default, so the thick of the slice will be 20cm)
Hsoil	Needed for the function Zsoil. Indicates the height of the points held above ground to create the DTM. If the field is generally flat, the 4 m by default are sufficient, however for a fairly steep terrain, it may be necessary to increase the value of Zsoil.

Value

Returns a data.table containing the points X, Y, Z, and Zr (created with Zsoil) located between (1.3 - ThickDHP) & (1.3 + ThickDHP)
