added code to profile aspect near 60N boundary (just like slope code)

separated out code to profile slope near 60N boundary

added GRASS/R code to run/compare flow analysis on Oregon test area

added GRASS terraflow code plus basic R diagnostics for 60N test case

added slope boundary descrepancy plotting code

added GDAL/R code for fusing and correcting DEMs near Canadian border

Set of shell scripts used to create prototype terrain mosaic layers from CGIR SRTM and ASTER GDEM data tiles.
Two prototypes generated: 3 ArcSecond and 30 ArcSecond resolution. There are some minor inconsistencies in these scripts; however, the mosaic layer components that they generate appear to be valid, except for some...

First version of this script; dKc constant is not optimally set yet. Need more experimentation.

Version of pixel pair plotting script that adds 'Lowess Lines' to center of each scatterplot.

Note: Loess lines feature has only been tested with the input file "pixelPairs36000_5_8EvenSortCol1.csv", used in the script.
Some table column names are hard-coded into the script.

This version has improved, vertically-stacked plots.
