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!

I'd also like to recommend the Texas Natural Resources Information System.
www.tnris.org
They have 500 gigs of all public domain geospatial information covering the entire state of Texas. They also have 8 terabytes of in-house data.

The link to capcog is also incorrect.
