ReadMe file describes how to use shell scripts (also checked in) to create example Srtm/Aster DEM image mosaic of Western Canada region spanning 60 deg N Latitude boundary
Sample output file from R script makeMarkTable.r - sample of 4000 random columns, row 5 through row 8 straddling 60 degree boundary.
Producing valid table, but from column samples taken entirely from mosaic. Next step: take them from Aster and Cgiar images.
First version, has issues with column indexing, I am fixing tonight.
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.
added empty dir structure for terrestrial work
