[mapguide-users] Niewbie: Converting Tiff to ECW

[Dumas A]

Yes, images are tiled and have build pyramids (it should be same like
overviews). MGOS and data is in same Server. But all files are about 400GB,
(1000files ~350mb). Project will be used to provide data via www and WMS to
local network.

So, whats better tiff or ECW?
