Raster TIF format Help

[Stephen Woodbridge]

Ed McNierney, et al,

What is the conventional knowledge on how to organize TIF images 
internally for optimal access by mapserver?

I remember that TIF files can have a lot of different internal 
organizations and that some are much more efficient for mapserver to 
access when serving data.

I am looking at putting together some topo map scans and Landsat imagery 
of the middle east. The topo maps are roughly 4000x3000 pixels and in 
various scales like 500k, 200k, 100k, 50k, and the landsat imagery is 
looks to be in 1 deg squares.

Can GDAL be used to reorganize the images and if so what options should 
I specify? or are there other tools I need to use?

Thanks,
   -Steve
