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

05:05 PM Revision f028b3dc: These scripts are complete but may not run correctly due to conflicts in the extents of the input raster files. Recheck inputs.: Rick Reeves
05:04 PM Revision 5c833657: Version runs correctly, though the CDEM edge input image might not be the latest and best. Recheck inputs: Rick Reeves
03:12 PM Task #212: Validate fused DEM at SRTM/ASTER boundary: 5/10/2011
Rick R -
To (finally) completely respond to Rob G's request:
(Work was delayed because of unexpected p... Rick Reeves
02:20 PM Task #212: Validate fused DEM at SRTM/ASTER boundary: ... Rick Reeves

05:20 PM Task #207: Produce global fused DEM layer: Using a subset of the ASTER 'master tile list' (supplied by Bob Crippen at JPL) containing only the image tile file n... Rick Reeves

04:10 PM Task #212: Validate fused DEM at SRTM/ASTER boundary: Jim, I agree. You can in fact see the 1/2 pixel 'offset' in the screenshots that I captured
of the magnified ArcMap ... Rick Reeves
09:02 AM Task #212: Validate fused DEM at SRTM/ASTER boundary: ... Rick Reeves
07:40 AM Task #212: Validate fused DEM at SRTM/ASTER boundary: Two points regarding DEM raster extents and alignments:
* At least for SRTM, the pixel _*centers*_ are lined up al... Jim Regetz
03:57 PM Task #219: Good News: JPL provides comprehensive Global List of ALL ASTER DEM files: I re-read Bob's email; he notes that the file list for the GDEM2 data set should be 'the same or close' to
the GDEM... Rick Reeves
03:52 PM Task #219 (Rejected): Good News: JPL provides comprehensive Global List of ALL ASTER DEM files: I asked the technical POC for the ASTER Data Product if a master list of ASTER DEM files/tiles
was available for us... Rick Reeves
08:55 AM Task #207: Produce global fused DEM layer: Here, for the team's comment and feedback, is my proposed plan for producing the global Fused 1 Km Terrain layer.
... Rick Reeves

02:36 PM Task #212: Validate fused DEM at SRTM/ASTER boundary: I have created and checked in a readme file which documents the steps I used to
generate one of the first image mos... Rick Reeves
02:29 PM Task #212: Validate fused DEM at SRTM/ASTER boundary: ... Rick Reeves
01:09 PM Revision f9dbcec6: 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: Rick Reeves
11:05 AM Revision 0f948be9: Sample output file from R script makeMarkTable.r - sample of 4000 random columns, row 5 through row 8 straddling 60 degree boundary.: Rick Reeves
11:02 AM Revision ad35c236: Producing valid table, but from column samples taken entirely from mosaic. Next step: take them from Aster and Cgiar images.: Rick Reeves

05:47 PM Revision b67964e8: First version, has issues with column indexing, I am fixing tonight.: Rick Reeves
