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.

First version of 'image blending' solution that employs a linear decay function to blend ASTER and SRTM pixel values south of 60 degree N Latitude line.

First version of ASTER/SRTM boundary adjustment R script that tests a prototype 'exponential decay' function on a sub image of the DEM imaage mosaic.

First version of R script that adjusts the boundary between ASTER and SRTM components of DEM image mosaic created for Environment and Organisms project. This prototype version uses a set of 'narrow' test images, applies a linear ramp function. Later versions will use more sophisticated functions.

this table created using the latest and best-aligned versions of the 'boundary validation' (ASTER/SRTM/CDEM) subimages. Input to the script: CreateImageDiffPlotsOverlayNewPlots.r
