Thanks for the links, B! I’ll check them out when I’m back in the land of broadband.

While I haven’t looked, can you recommend any sites who talk more about various forms of photo imagery such as visual, UV, thermal, etc.

Also if it isn’t stepping on any confidentiality issues, what is the number of mega-pixels that is considered highest resolution for the USGS purposes?

Edit: also how big is a big CCD considered to be?
