Visualizing Twitter Activity Inside the Google Earth Plugin

February 9th, 2009 No comments

Twitter, Google Earth PluginHere’s a browser based version of the (Feb 2009) UK Snowstorm Twitter activity, animated inside the Google Earth Plugin.

This mashes up 3800 Tweets over the course of a week. Users posting their location and the amount of snowfall they were seeing on a scale of 0 to 10. You can see how Twittersphere activity peaks on Monday February 2nd, the day the country ground to a halt. With sporadic outbursts every day over the following week.

Embedded, below the fold.

#uksnow Twitter Animation – Google Earth 5

February 3rd, 2009 8 comments

A much more significant event than the release of Google Earth 5.0 yesterday was the fact the much of Britain (particularly S. England) was covered by a sprinkling of snow. 😉

As a knock-on of this there’s been a large amount of media buzz about the use of Twitter as a mob-sourced geo-mashup generator to show snowfall.

Twitter users have been posting the first half of their postcode, plus the amount of snow in their location. 0 = no snow, 10 = bucket loads. ie: “#uksnow W12 9/10”

Developers have been mashing-up that data. Check out Ben Marsh’s neat, live Google Map mashup of this: #uksnow Tweets

Now that the flurry (sorry) of activity has died down, I’ve trawled the Twitter API for the past few days of #uksnow hash tags (2200 so far) and put them into a KML time animation tailored to run in Google Earth 5:

Download the kml file, and use the time slider at the top left of the screen to play it back.

Couple of new techy things to notice if you have the new Google Earth version.

  • I’ve used the KML gx:TimeSpan element in my Document level lookAt so that by default the time slider displays one hours worth of Tweets. Notice how GE flys back in time after the KML loads.
  • The icons expanding and contracting during playback is a built-in feature of the new version of GE.
