[UW-GIS-L] NAIP $-band Orthoimagery (fwd)

[Meghan Halabisky]

Thanks Matt,

I much prefer option #1. The uncompressed images are necessary for any
remote sensing application. However, I bet the GIS users would prefer the
smaller file size so if it is possible to get both options or if someone
could compress the tiff file I am sure many people would be happy.

Cheers!
