sq: Calculates the Root Mean Square Roughness of a Surface
In geodiv: Methods for Calculating Gradient Surface Metrics
sq R Documentation
Calculates the Root Mean Square Roughness of a Surface
Description
Finds the root mean square roughness of a surface
(Sq) as the standard deviation of surface heights
from the mean surface height. Height is measured as
the value of a raster and may not necessarily
represent actual height.
Usage
sq(x)
Arguments
x
A raster or matrix.
Value
A value of root mean square roughness in
the units of the original raster or matrix.
Examples
# import raster image
data(normforest)
normforest <- terra::unwrap(normforest)
# find the surface roughness
roughness <- sq(normforest)
