This is a deprecated function. Use terrain

slopeAspect(dem, filename='', out=c('slope', 'aspect'), unit='radians', neighbors=8, flatAspect, ...)
dem |
RasterLayer object with elevation values in map units, or in meters when the crs is longitude/latitude |
filename |
Character. Filename. optional |
out |
Character vector containing one or more of these options: 'slope', 'aspect' |
unit |
Character. 'degrees' or 'radians' |
neighbors |
Integer. Indicating how many neighboring cells to use to compute slope for any cell. Either 8 (queen case) or 4 (rook case), see Details |
flatAspect |
Numeric or NA. What value to use for aspect when slope is zero (and hence the aspect is undefined)? The default value is 90 degrees (or 0.5*pi radians) |
