| 説明 | Data from Flickr, Picasa, and Twitter geotag pairs (through December 6, 2010), routing away from geotag density.The five East Bay locations that are well connected to San Francisco are (from top to bottom) downtown Berkeley, downtown Oakland, Park Street in Alameda, the Coliseum, and Oakland Airport.There are a lot of documented trips between SFO and downtown San Francisco, probably from people tweeting or photographing these two milestones of their arrival.Square root of frequency, with brightness bumped up by hand. Smoother gradients in the sparse areas would be better, to avoid making the lines so wobbly around the few locations where there are geotags. |
