Before Google Pro became "free" to use the historical index had aerials back to the 1950's. It appears that ability has been lost and now I can only go back to 1993.
I can not find a site where I can view aerials from the 1950's for free any more. I hesitate to order the photo from NGS because I am not sure that it will show the detail that I need. (Location of the top and bottom of bank around 1957)
I tried EarthExplorer, Terraserve, and the MA Oliver GIS site.
Does anyone have any ideas?
I use EarthExplore, It is slow but it does the job. I too would like a better way to browse historical photo's. :good:

I like EarthExplorer quite a bit. I'm sure you've noticed that the scale of the photo appears beside each image available for download as well as time of year and the area covered by each photo (which means you can determine how close to the principal point the area of interest is).
If I had a really slow internet connection, I'd probably be much more bothered by having to download the image to see it in any detail since the file sizes at maximum resolution approach 100MB.
Remember. You get what you pay for. I needed to find some historical aerial photos of the Hanford research area in Washington and all the normal avenues had a large black hole. I found some in the Denver office of the Soil Conservation Service. Evidently they didn't get the memo banning aerial photos of the nuke research facility.
I don't have GE pro. Just regular. I can still go far back but then again I haven't updated. Guess I won't be!
It may still be possible to upgrade to GE Pro, all it takes is filling out and sending an application and they will send you a key by email to unlock the features. The key will work on two computers.
There are a few tools that GE has kept that allow you to know the area of any polygon you create and to take snapshots of the screen by save to file. It is much better than printing to paper or using Adobe to print to pdf. Create a .tif and open in a program like IrfanView to create many other forms to present your creation.

Snapshot of the screen? Isn't that the same as just 'screen print' and pasting to a photo program such as paint?
Probably, I discovered the function last week.........
The command in GE and GE Pro is under the Edit menu
Still have a problem remembering and finding where the file is saved.........
Sometimes I luck out with www.historicaerials.com but it's resolution and date range can be limited.
GE Pro is free. Use your email address for the username and "GEPFREE" for the password and you will be good to go.
You can download here: http://www.google.com/earth/download/gep/agree.html&apos ;">GEPRO and the instructions for 'Free' are on the right hand side.
