r.param.scale

GRASS module that extracts terrain parameters from a DEM.
Uses a multi-scale approach by taking fitting quadratic
parameters to any size window (via least squares).

Jo Wood, 27th November, 1994.

-------

Modified to include constrained fitting.

Jo Wood, April, 1995

-------

Modified to include weighting matrix and double precision arithmetic.

Jo Wood, 9th May, 1995.

-------

Modified to include two separate tolerance values for feature detection.

Jo Wood, 23rd May, 1995.


-------
Still to do:
Fix bug when `constrain through central cell' option selected.
Create colour tables for all output files (presently only on features).

-------

See also Java Code in 'LandSerf' that implements the same procedure
(http://www.geog.le.ac.uk/jwo/research/LandSerf).

-------

Usage:
r.param.scale [-c] in=name out=name [s_tol=value] [c_tol=value]
[size=value] [param=name] [exp=value] [zscale=value]

Flags:
-c Constrain model through central window cell

Parameters:
in Raster surface layer to process
out Output raster layer containing morphometric parameter
s_tol Slope tolerance that defines a `flat' surface (degrees)
default: 1.0
c_tol Curvature tolerance that defines `planar' surface
default: 1.0
size Size of processing window (odd number only)
default: 3
param Morphometric parameter to calculate
options: elev,slope,aspect,profc,planc,longc,crosc,minic,maxic,
feature
default: elev
exp Exponent for distance weighting (0.0-4.0)
default: 0.0
zscale Vertical scaling factor
default: 1.0
