Flickr data stream 2009-2011 for California
[new version with higher resolution ]
This is a visualization of the amount of photos posted during the time from 2009 to 2011 in California (looking North to South along the coast).
As you can see, San Francisco Bay Area and LA County are clearly the densest hot spots.
Look at Lake Tahoe peaking in winter months and Yosemite and other national parks in summer.
Height of bars was calculated using Natural Breaks algorithm - this means super hot spots like San Francisco downtown appear much lower than they are whereas areas with small amount of photos appear much bigger.
