Infrared Image Layers?

[SeanGerhardt]

Hello,

Does anyone know where I could find Infrared image layers? I've heard landsat 5 may have some IR data, but is there any other data that is freely available? I'm specifically looking for IR images for western Minnesota.

Thanks!

You might check out the NAIP photography.  In 2008 they may have produced 4 band imagery.  If so you just remap the RGB bands from their usual 1, 2, 3 to 4,2,1 and you have color IR.  You could check the MN state GIS site to see if any are available, or go to the US Data Gateway site for county wide mosaics.
