Open Source in Short: Retracing a UK Street 100 Years On - bellingcat

An amateur restorer discovered slides showing street scenes from early 20th century Middleton , UK .

He was keen to find out where exactly they were taken.

Using historical Ordnance Survey maps we were able to independently locate a number of the images.

By combining the ordnance survey with historical photos and postcards we geolocated where the historical photos were taken and gained an approximation of how the street would look at the time.
