Free GIS Data Tip: Orthophoto Servers and FTP sites... enjoy!

Looking for orthos? Here's a decent reminder list that I published a while back... always useful for reference.. enjoy. The data from the SDDS is available as a seamless product on the Seamless Data Distribution System see http://seamless.usgs.gov The imagery is available for online download as small files or larger areas may be purchased on media (CD or DVD). Looking for more free resources & FTP sites?  Other Sources of Orthophotos & imagery are provide in this list - try these and please, stop buying free, public domain data ;0) - this list is by no means complete but its a good starting point!
