[mapserver-users] Mr Sid vs ECW

[Brent Fraser]

Mark,

   These days disk space is easier to come by than time, in general.  As Jeff 
points out, GeoTiff is fast (especially if you use TILEINDEX and 
MAX/MINSCALEDENOM layers for pyramid/overviews).  But GeoTiffs tend to take up 
10 to 20 times the amount of disk space of ECWs though...

   Is there any particular reason not to use tiles (e.g TMS)?
