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

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

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
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

10:56 AM Task #207: Produce global fused DEM layer: Here is an example of the workflows that generate fused digital terrain data layers
for one of the four Earth 'quadr... 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

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.
