Standard error output (stderr)
... (lines omitted)
Generates raster maps of slope, aspect, curvatures and partial derivatives from an elevation raster map.
Aspect is calculated counterclockwise from east.
Keywords:
raster, terrain
Usage:
r.slope.aspect [-a] elevation=name [slope=name] [aspect=name]
[format=string] [precision=string] [pcurv=name] [tcurv=name] [dx=name]
[dy=name] [dxx=name] [dyy=name] [dxy=name] [zfactor=value]
[min_slp_allowed=value] [--overwrite] [--help] [--verbose] [--quiet]
Flags:
-a Do not align the current region to the raster elevation map
--o Allow output files to overwrite existing files
--h Print usage summary
--v Verbose module output
--q Quiet module output
Parameters:
elevation Name of input elevation raster map
slope Name for output slope raster map
aspect Name for output aspect raster map
format Format for reporting the slope
options: degrees,percent
default: degrees
precision Type of output aspect and slope maps
options: CELL,FCELL,DCELL
default: FCELL
pcurv Name for output profile curvature raster map
tcurv Name for output tangential curvature raster map
dx Name for output first order partial derivative dx (E-W slope) raster map
dy Name for output first order partial derivative dy (N-S slope) raster map
dxx Name for output second order partial derivative dxx raster map
dyy Name for output second order partial derivative dyy raster map
dxy Name for output second order partial derivative dxy raster map
zfactor Multiplicative factor to convert elevation units to meters
default: 1.0
min_slp_allowed Minimum slope val. (in percent) for which aspect is computed
default: 0.0
