Description

This function clips GEDI level2B derived Plant Area Volume Density profile within a given bounding coordinates

Usage

1
clipLevel2BPAVDProfile(level2BPAVDProfile, xmin, xmax, ymin, ymax)

Arguments

level2BPAVDProfile

A GEDI Level2B object (output of getLevel2BPAVDProfile function). An S4 object of class "data.table".

xmin

Numeric. West longitude (x) coordinate of the bounding rectangle, in decimal degrees.

xmax

Numeric. East longitude (x) coordinate of the bounding rectangle, in decimal degrees.

ymin

Numeric. South latitude (y) coordinate of the bounding rectangle, in decimal degrees.

ymax

Numeric. North latitude (y) coordinate of the bounding rectangle, in decimal degrees.

Value

Returns an S4 object of class data.table-class containing the Plant Area Volume Density profile data.
