sdq: Root Mean Square Slope of Surface
In geodiv: Methods for Calculating Gradient Surface Metrics
sdq R Documentation
Root Mean Square Slope of Surface
Description
Calculates the root mean square slope of a raster or matrix
surface using the two-point method.
Usage
sdq(x)
Arguments
x
A raster or matrix.
Value
A numeric value representing the two-point root
mean square slope, Sdq. The units of the returned value
are change in z per one unit (pixel).
References
This function is based
on the equations found at
https://www.ntmdt-si.ru/data/media/files/manuals/image_analisys_p9_nov12.e.pdf.
Examples
# import raster image
data(normforest)
normforest <- terra::unwrap(normforest)
# calculate root mean square slope
Sdq <- sdq(normforest)
