674bbf95 07/15/2011 04:58 PM Rick Reeves

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...

74edc384 06/13/2011 05:42 PM Rick Reeves

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

e11b5636 06/13/2011 02:47 PM Rick Reeves

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.

05968504 06/01/2011 02:59 PM Rick Reeves

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.

ec0af318 05/18/2011 11:42 AM Rick Reeves

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

4101796f 05/18/2011 11:10 AM Rick Reeves

The input file pixelPairs36000_5_8EvenSortCol1.csv also checked in.

8fd072d3 05/16/2011 04:11 PM Rick Reeves

80390607 05/13/2011 03:19 PM Rick Reeves

First working version - very simple - just 'source' the file and press <CR> to walk through the plots.

Next version: 'panel plots' and improved plot axes.

d732553c 05/13/2011 02:38 PM Rick Reeves

Very first version of plot making script. Plots need consolidation into 'panel plots', and plot labels need to be improved.

Uses input file:
tableForMark4000_5_8_SortColID.csv, also checked in.

f028b3dc 05/10/2011 05:05 PM Rick Reeves

These scripts are complete but may not run correctly due to conflicts in the extents of the input raster files. Recheck inputs.

5c833657 05/10/2011 05:04 PM Rick Reeves

Version runs correctly, though the CDEM edge input image might not be the latest and best. Recheck inputs

ad35c236 05/05/2011 11:02 AM Rick Reeves

Producing valid table, but from column samples taken entirely from mosaic. Next step: take them from Aster and Cgiar images.

b67964e8 05/04/2011 05:47 PM Rick Reeves

First version, has issues with column indexing, I am fixing tonight.

230f2a79 05/02/2011 04:41 PM Rick Reeves

Added collection of Linux shell scripts and R scripts that I used in my initial analysis of SRTM/CGIAR, CDEM, and ASTER GDEM digital terrain data sets.
