The USDA makes aerial photography available for many counties in United States. You can acquire a natural color mosaic for most of these counties for $50.00. We recently discovered that these mosaics are only made available in MrSID format. The mosaics are very large files and you need to purchase LizardTech's GeoExpress or other commercial software to "cut" up the MrSID images into more manageable chunks.
I think it's a shame that the files are in a proprietary format, but LizardTech does at least offer a free "MrSID Decode" program that will extract slices from them into JPEG or TIFF format. You can get it from http://www.lizardtech.com/download/dl_options.php?page=tools Eric
