Palletizing Bulk Tiled Imagery

[Fawcett, David]

This sounds like a great candidate for a 'How-To' on the MapServer site,
or an addition to the existing Raster Data Access How-To:
http://mapserver.gis.umn.edu/docs/howto/raster_data

Another great candidate for a How-To would be 'Data Optimization',
broken into Raster and Vector sections.  We continually get list
questions about how to make big datasets faster, it would be great to be
able to point to one document.  One could probably just scrape most of
the great emails from Ed on the subject.  I may start one if I get any
time.  

David.

Here is a slightly modified version of that
http://www.vso.cape.com/~nhv/files/gdal/gdal_vrtmerge.py

# modified output of geotransform to retain same numerical
# precision as the gdal 'C' utilities

and here is the recent announcement of a 'C' version

Cheers
