Have you ever wondered what San Francisco was like before the techies invaded? Well, now you don’t have to.
Two developers have cleverly created OldSF – an interactive Google Street View-style map of the city made up of photos dating as far back as 1850.
The geocodes were determined in two ways – by the image’s subjects and by cross-referencing the addresses with coordinates using Google Geocoding API.
When you zoom in on the map, you can move the slider to see the range of years and collection of images related to that area in particular.
It’s a neat way to discover some history about the city and explore without talking any open top bus or walking tour.
