1. Photo Subjects. All photographs in the “City Hall (old)” series presumably belong in the same place. We manually geocoded several hundred subjects.
2. Addresses and Cross-Streets. The photo descriptions often contain either an address, block number or set of cross-streets. These were converted to coordinates using the Google Geocoding API.

This is yet another great example of the benefits of living in a city with so many passionate and talented developers. I'm so thankful I live here
Very nicely done. Reminds me of all the walking I did during my second pregnancy (we lived where Noe dead ends at Laidley).
Looks much like http://www.historypin.com/ , but geographically restricted and with more photos of SF.
Amazing. Did they geolocate each photo by travelling around the city and eyeballing it?
According to http://www.oldsf.org/about:
The geocodes are based on two sources:
1. Photo Subjects. All photographs in the “City Hall (old)” series presumably belong in the same place. We manually geocoded several hundred subjects.
2. Addresses and Cross-Streets. The photo descriptions often contain either an address, block number or set of cross-streets. These were converted to coordinates using the Google Geocoding API.
Brilliant work, it must have taken thousands of man-hours to do this. I'm really enjoying looking through it.
That is amazing thanks for sharing. Was very cool to go to the different neighborhoods I have lived and see what it looked like 100 years ago.
I just spent a good hour of my life on this site and I don't regret it. Thanks for making this.
