Daniel Catt from Flickr maps 24 hours worth of geotagged photos (about 64,000 of them) on this animated 3-D globe (below). The project was implemented in Processing, which shouldn't come as much of a surprise to anyone, and we've seen this type of 3-D globe thing before. What's cool here is that all the data came from the Flickr API:
All the data was pulled down (using Processing, of all things) via the API, and probably took around 12 minutes (when it's behaving itself) as I was being a) gentle with the servers b) was getting it as JSON which takes a while for Processing to parse each page. And then written to a flat file.
I didn't realize that public Flickr data was so accessible. Although, there wasn't really any reason for me to think otherwise. Maybe it's time to consider a little Flickr side project with some Modest Maps.
