05:41 PM Task #207: Produce global fused DEM layer: Steps:
>1) Identify base DEM data sources
>2) Define regions for which each base data type are required
>3)... Rick Reeves
04:44 PM Task #215: Establish file organization and possible 'tiling' scheme for Fused Global Terrain data set: The complete archive of Digital Elevation Model data to be used for constructing the Fused Terrain Layer and derived ... Rick Reeves

05:49 PM Revision 8ff00cae: 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.: Rick Reeves

09:19 PM Task #225: Organize and document SRTM input DEM files: I accumulated the (SRTM and ASTER) DEM files over the past two months, as I began this project. The ~ 6000 files are ... Rick Reeves

02:59 PM Revision 05968504: 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.: Rick Reeves

04:45 PM Task #207: Produce global fused DEM layer: Progress during week of 5/16:
> 1) Located and downloaded most if not all ASTER GDEM data tiles for Northern Hemisph... Rick Reeves
01:20 PM Task #225: Organize and document SRTM input DEM files: h4. Re: Different CGIAR SRTM 3" source data
Rick and I have been discussing the two different sets of CGIAR SRTM r... Jim Regetz

10:26 AM Task #225: Organize and document SRTM input DEM files: Yes, last week I created a new folder structure to contain the batch files and output files
for the next set of 'pr... Rick Reeves

11:42 AM Revision ec0af318: this table created using the latest and best-aligned versions of the 'boundary validation' (ASTER/SRTM/CDEM) subimages. Input to the script: CreateImageDiffPlotsOverlayNewPlots.r: Rick Reeves
11:10 AM Revision 4101796f: Added option: write individual plots (not trplets - yet) to separate JPG files. New command line argument: JpgPlotFileFlag: Rick Reeves

05:33 PM Task #225 (In Progress): Organize and document SRTM input DEM files: _[Updated ticket description on 04-Aug-2011 to focus specifically on SRTM]_
SRTM DEM tiles and associated files ha... Jim Regetz
12:13 PM Revision db78f686: Table used by CreateImageDiffPlotsOverlayNewPlots.r: to create latest set of (normalized) difference scatterplots Rick Reeves
12:12 PM Revision cc196a45: This version used to create the large (36000 row) table used to generate latest bounday analysis scatterplots.: Rick Reeves
12:11 PM Revision acf2afb2: This version creates the (normalized) difference image plots: that Rick, Jim, and Mark are reviewing as part of the final 'ASTER/SRTM boundary analysis' work.
The input file pixel... Rick Reeves
10:47 AM Task #207: Produce global fused DEM layer: Today I received an email from Rob G regarding progress on data layer construction; among the items in the email was ... Rick Reeves

11:05 PM Task #215: Establish file organization and possible 'tiling' scheme for Fused Global Terrain data set: I am using this scheme; have created the directory structure, and have constructed
the first prototype fused global... Rick Reeves
