You don't really say what the problem is, and you don't say what
happened when you "didn't succeed".  For example, when you used
gdaltindex, what result did you expect and what result did you get?
=20
First, do your several dozen raster images taken together form a tiled
data set?  Or are you trying to divide each of those files into smaller
rasters and then tile those back together?

Subject: [Mapserver-users] Tiling Tif Images
=20
Hi list,

hmm, I think I read everything concerning the tiling of raster images by
now. But the best hint I've found was the following URL (
http://remotesensing.org/gdal/gdal_utilities.html ). I read as well this
document ( http://mapserver.gis.umn.edu/doc/raster-howto.html ), but no
solution in sight. I tried to find the gdaltindex (for windows), but did
not succeed. I have the OpenEV installed, but this does not offer
tiling. =20

Fact is: I have several dozens of raster images which are mostly between
100 and 500 MB. So, would you recommend to do some tiling with these
sizes? If yes, what tool should I use?

Can someone give be a tip?

Thanks,

Stefan
