In my own efforts in this space (admittedly only 13.5 million dots) I merged the two classified sets of dots by assigning each a random number and then reordering them...hence creating the illusion that red and blue were mixed in visual balance. It seemed to work. You could have a 'red', a 'blue' and a 'mixed' version?Kenneth Fieldhttps://www.blogger.com/profile/16738467752479352030noreply@blogger.comtag:blogger.com,1999:blog-8123225361504762353.post-37781932389141992132013-06-22T08:32:25.797-07:002013-06-22T08:32:25.797-07:00Thanks for the analysis.

The original had everything composited together but we made it separate layers so they could be toggled, and it was a bad idea because of the precedence. Trying to figure out now how to make it more honest.<br /><br />Interesting point about the difference between travel and tourism. They are kind of the same thing, but I guess there is a difference in intent: stopping because you have to vs. stopping because you are interested in something. I don't know if there is any way to discern intent from tweets, but photos are probably better because they do indicate that you were looking for interesting things.<br /><br />I wish the sample size was larger, but I think the density is still legitimate, because counts of geotagged tweets on streets do correlate well with pedestrian counts on those streets. The big places where it falls apart are retirement homes, because that age group really doesn't use Twitter much.Eric Fischerhttps://www.blogger.com/profile/17717107532168518915noreply@blogger.com
