circularDispersionNV: Compute circular variance of normal vectors to surface

In SurfRough: Calculate Surface/Image Texture Indexes

Compute circular variance of normal vectors to surface

Description

Compute circular variance of normal vectors to surface, using the resultant vector length

Usage

circularDispersionNV(inraster, window)

Arguments

inraster	The DEM from which compute the index
window	The moving window adopted for computing the index

Value

The raster with the computed index

Examples

#
#Normal vector dispersion using a circular search window of radius 3.
library(terra)
dem=rast(paste(system.file("extdata", package = "SurfRough"), "/trento1.tif",sep=""))
w=KernelCircular(3)
roughVDR=circularDispersionNV(dem,w)
plot(roughVDR)
