Historical Aerial Photos

I'm performing a Phase I ESA in NW Colorado, and need to do my historical research. Does anyoneknow of an online place to view them for free? I don't need to print them, I just need to view and comment.

I don't know of a federal website that provides one-stop shopping for aerial imagery. Your State web site would very likely have a spatial data library link somewhere - In Mich, there is a Center for Geographic Information library (on-line), part of the Dept of Information Technology, formerly accessed thru the Dept of Natural Resources. Anyways, in example, you can perform searches by county, finding aerial imagery, satellite imagery, land use / cover shapefiles, public land survery (PLS) features, DEMs, transpo frameworks, you name it! Possibly your state has similar on-line resources(?)

I was going to suggest checking your state's GIS database too.

The other place I found them, in Vermont at least, was through the Dept. of Taxation. Seems like an odd place to go for that, but I can only guess they had them for use in developing the tax maps.

how historic? Terraserver.com sometimes goes back as far as 70's-80's, but there was a lot of 90's.

I need to '1940 or first developed use, whichever is earlier.' Thanks for all the suggestions...I will try them today.

I would suggest a phone call to your state GIS service. I strongly doubt that images from the 1940's would be readily accessible for online viewing. It might be time for a trip to the library.

good luck
