I have two doubts (well probably even more than 2) that maybe somebody =
can help me to solve.
1) I still use the 3.6 version and therefore I have to optimize the =
raster laters to 256 colors. When i will be able to use 24 bit color =
rasters what will happen to the performances in that same raster layer? =
I mean, sometimes 256 volors are really unacceptable but maybe in some =
situations it's only a matter od graphic perfection (a DTM for example) =
and 256 colors are not so bad. In these situations maybe one could =
choose to go for the 8 bit just to preserve performances even id we =
could serve it 24 bit.=20

2) I didn't understand very well all the characteristics of WMS and the =
differences of chooseing this platform instead of a normal mapserver =
engine. Can anybody suggest a good resource (pref. online) where i can =
improve my knowledge? I understood that a wms is the solution when =
mapping is only a part of the application i am buiding cause i insert =
the map service inside it like a component. But if i am developing an =
application in which mapping is the main goal probably it's better =
(performances?) to choose a more traditional way to serve maps.

Thanx
Giorgio
