[mapserver-users] areas of high res

[Wendell Turner]

The base layer of my map has full coverage of the US at a
scale of 1:500,000.  That works fine.  I have some areas of
detail that have tif files at a scale of 1:250,000.  What do
I put in the mapfile to say 'use high res if available for
this tile, otherwise use the low res one'?

Thanks,

Wendell
