Penn Pilot

This site has been available for a few years, but they have made it more user friendly. Historic aerial photos of Pennsylvania can be downloaded in zip form, and when extracted they have to be dragged to a new folder in order to view them. A good photo program makes them easier to view. The hi-res photos are about 6MB

It is a great resource for PA modelers. I wish we had the same for Ohio.

I found some for the Phoenix Arizona metro area on the Flood Control District's website. Historic aerial photos are probably available for many areas of the United States, it's just a matter of finding who has them. Most probably aren't online in a convenient browser such as this. I'm sure they are available for Ohio - somewhere.

I've been using Penn Pilot for a long time now. Combining Penn State's work with Penn PIlot with the University of Pittsburgh's maps and photo archives of their city, one can get a lot of help with a track plan. Sheets 25 and 26 of the City of Pittsburgh Geodetic and Topographic survey and APS7278 from the USDA photo surveys have given me everything I need to know.
