Not at all! Just to be clear... in this context "historical structures" means "things that aren't there anymore".
Do you see anything likely to be that old barn?
I search for lost buildings/cellar holes on Historical aerials but your map makes it much easier to see larger areas at a glance and then check the aerials for confirmation.I use your 1930 aerial frequently ,the 1940';s amd 50';s are clearer but of course the 31 shows buildings that fell down prior to the 40;sNo, that's why I asked you! Most of my historical stuctures were traced from vintage topo maps, so the location is approximate and size is not very accurate. Now that I have a very complete dataset of contemporary structures from Microsoft (about 1.8 million on my new map), it's very interesting to overlay these on the old topo maps. Right away you notice buildings that no longer exist.
1956, yep those were the maps I used to use when I was poking around in there.
That photo is one of many that were posted by member @Pan back in 2013. Here's the original thread with lots of cool photos: https://forums.njpinebarrens.com/threads/i-found-a-few-more-pine-barrens-photos-c-1970-or-so.9133/
It's been almost two years since he has checked in here, I hope that all is well with him.
