The FoundSF Geotagger

FoundSF-Geotagger.jpg It's fast, fun, and extremely helpful! Join the community of San Francisco locals helping to crowdsource the geographic information for the historical photos in FoundSF. At the same time you will be providing the coordinates we need to build a new map interface for our collection.

Once you have the app on your iPhone, you can locate images from the FoundSF collection by neighborhood and drop a pin to identify the location of each one.

Everything you need to use is explained on the app page itself.

Special prizes will be announced for monthly winners!
