Hi Group,

=20

I would like to use different resolution images (tiffs) in my mapserver
application. For example, for global scale I need to use a 50km
resolution image and as the user zoom in I need to use one of the 8 km
resolution images specific to that area, and if the user further zooms
in, I need to use one of 1 km resolution images. Do I need to use a
TileIndexing/SHPTREE for this? Is there a way to do this?

Thanks a lot
