They made it easier to see back in the day, cheesy as some shots are, it means a lot when looking for a past reference. Right on Google earth.
Have you seen the update to google earth?

Before drones it was aerial photography from a plane.
I remember seeing big white cross hairs and right angled lines painted on some roads back in the day.
These were registration marks to line up the aerial photos to make a map
We have it easy today with software to stich together a photo in seconds vs. days of producing photos from film in a darkroom.

Thanks for sharing.
That you for you response, it's appreciated.
I use google earth to look at past areas where I've lived and worked in the past and until now for me to see back say 30 yrs and was very difficult to see these satellite views easily. Now it's much easier after the update to view simply go to the years with a new slider option.

I still don't get it, the time slider has been there for more than a decade?
Yes, very true I know. What I'm saying it's a bit easier now to use, at least for me using the new slider style for time, because it is different type of slider. God I'm getting old

In 1968, I was fresh out of high school and was working for a surveyor. Between surveys of lots or doing topo work, the company would have us check out aerial photography, taken from an altitude of 4,000’ between 2 points on the ground. My partner and I, using a 300’ chain would measure from a starting point marking each 300’. The survey party chief would then point out discrepancies between the reference photos and actual measurements.
Looks like all Tech has learning curves. Thanks, very interesting to find out.
I actually am a retired land surveyor, after 43 years in the business I decided it was time to relax & enjoy life a bit. The white aerial "x's" referred to on the ground are known as aerial panels. Today a fair amount of land survey companies do there own aerial flights using drones and in house software bypassing hiring aerial photogrametry company's.
Droning on and on...

A friend of mine tried to tell me years ago, and I mean way way way back that this technology was coming and what it would be able to do in the future. I thought he was crazy because he talked about how Agriculture would be affected by it as well as other fields. Turns out he knew exactly what he was talking about. I should have paid more attention to what he trying to say to me because he was right.

Has anyone seen the crank for my Model T? I need to get to work......
Id like to see older images, but I don't see these functions in GE on my phone.
Historical option, on the same line as the search field you'll see a clock face and back arrow. Then historical tab pops up at least on my laptop anyway.
