In hrvg/statisticalRoughness: Estimation of roughness exponents across scale for large areas

Description

Rotates the detrended DEM according to the main direction of the Fourier spectrum

Usage

rotate_raster(rstr, ang_fourier)

Arguments

rstr	a RasterLayer
ang_fourier	numeric, angle of the main component of the 2D Fourier spectrum; the rotation is clockwise

Value

a matrix corresponding to the DEM rotated in the main direction of the Fourier spectrum

Examples

r <- raster::raster(ncol = 3, nrow = 3)
raster::values(r) <- 1:(raster::ncell(r))
raster::as.matrix(r)
raster::as.matrix(rotate_raster(r, 45))
