[Tilecache] Estimating disk space requirements

You can calculate the number of tiles exactly (obviously) but the problem is
the actual tile image sizes will depend on what kind of map you have...
blank/ocean areas and photographic imagery beeing the most important
factors. That's why optimizing the image output
(format/compression/metadata) from your mapserver is quite important. What
you could do is try to determine what the largest tile image would be and
use that multiplied number of tiles as the estimated maximum size for the
cache.
