[mapguide-users] MGOS2.0.1 & Raster Files Performance

[Gunter Becker]

Hi Max,

please habe a look at  http://trac.osgeo.org/fdo/wiki/FdoGdalNotes Creating
Tile Index Config Files . Maybe you can build a tile index for your
ecw-files. That will minimiz the file access. But I don't know if this works
with ecw.
