[Freegis-list] Next Generation Blue Marble Torrents

[Frank Warmerdam]

Folks,

The "Next Generation" Blue Marble datasets from NASA have
been converted to ECW format, and made available as torrents
at http://www.geotorrent.org/.

Each torrent includes 12 distinct world images for each month
of the year, each 86400 x 43200 pixels in size.  At 50:1 compression
these ecw files are about 260MB or 2.8GB per torrent.

Three versions exist:

Enhanced with Topolography and Bathymetry
  http://geotorrent.org/details.php?id=61

Enhanced with Topography
  http://geotorrent.org/details.php?id=60

"Real" View
  http://geotorrent.org/details.php?id=59

A variety of software package support the ECW format, including
the FWTools builds of OpenEV/MapServer/GDAL at:

Best regards,
