       dd..ppaarraamm..ssccaallee   - Calculates surface parameters and features from a DEM
       and displays them in GRASS monitor. It allows interactive  indentifica-
       tion  of  terrain parameters and features with a mouse. Reports member-
       ship classes for variable window sizes and their variance or entropy.

       The  GRASS  program _d_._p_a_r_a_m_._s_c_a_l_e can be used to identify interactively
       terrain parameters  and	features  with	a  mouse.  Reports  membership
       classes for variable window sizes and their variance or entropy.

PPRROOGGRRAAMM OOPPTTIIOONNSS
       _d_._p_a_r_a_m_._s_c_a_l_e can be run either non-interactively or interactively.  In
       non-interactive use, the user must specify the name of the  raster  map
       layer  to be used for input on the command line, using the form iinn==_n_a_m_e
       _n_a_m_e (where the	_n_a_m_e is the name of a raster map layer to be input.

       iinn==_n_a_m_e: Raster surface layer to interrogate



	ss__ttooll ==_v_a_l_u_e: Slope tolerance value
	      that defines a `flat' surface (degrees) - default: 1.0



	cc__ttooll==_v_a_l_u_e: Curvature tolerance value that defines a `planar'
	      surface -  default: 1.0



	ssiizzee ==_v_a_l_u_e: Size of
	      processing window (odd number only) - default: 15



	ppaarraamm==_v_a_l_u_e: Morphometric parameter to calculate options:
	      elev,  slope,  aspect, profc, planc, longc, crosc, minic, maxic,
	      feature, resid, moran, geary - default: elev



	eexxpp ==_v_a_l_u_e: Exponent for distance weighting
	      (0.0-4.0) 1 implies  a  linear  decay,  2  an  inverse  distance

		   planc:    Plan convexity (contour curvature).
		   crosc:    Cross sectional convexity (tangent  to  contours,
	      downslope).
		   longc:    Longitudinal convexity (perpendicular to contours
	      downslope).
		   minic:    Minimum convexity.
		   maxic:    Maximum convexity.
