threshr.accumbasicparams
Name: threshr.accumbasicparams

Description: Determine the cumulative area for each
subbasin, create a coverage of subbasin centroids, and compute
attributes that the depend on the cumulative Polygon Shapes
or cumulative Line Shapes.

Inputs: Subbasin Feature Attribute Table: shdftab
         Maximum area threshold: maxareaval
         Longest flow path FTAB: lfpftab (only required if
                 usgsslope or lcentroid = true)
         Dem Grid: demgrid
         Booleans:
             usgsslope-- true if channel slope will be calculated
                         using the USGS method
             lcentroid-- true if length to centroid will be computed
             regions-- true if region percentages should be calculate

Outputs: cumulative basin centroid shapefile
          adds ARM attribute to shdftab (area mi2)
          adds CHSL0 (channel slope -- max - min elev) (ft/mi)
          adds CHLN attribute

threshr.calculatefeaturegeometry
Name: threshr.calculatefeaturegeometry

Description: Slightly modified version of View.CalculateFeatureGeometry
that allows this script to be called from another script.
The required input FTAB is passed through the SELF object.
--------
Name: View.CalculateFeatureGeometry

Title: Calculates feature geometry values

Topics: GeoData

Description: Calculates area and perimeter for polygon themes and length
for line themes. If the View has been projected the calculations are in
projected meters. Otherwise the calculations are in native map units.
Modify the script to provide calculation in the current report units of
the View. The script processes the list of active themes to calculate
area and perimeter, or length, depending on the theme type.

The script will add the fields: Area and Perimeter to polygon themes, Length
to line themes if they do not exist. If the fields exist their values will
be recalculated. Rerun the script if you change the projection of the view.

Requires: A View with at least one active theme. You must have write access
to the active theme(s).
