Twitter Watermain Mapping – Part Two

Posted by: Skylar In: internet coverage|water

So, it seems like I jumped the gun by saying I could only add up to 15 results through the yahoo pipe.  A quick look at the comments on the original post about this yahoo pipe shows that there’s an argument in the twitter search api allowing you to specify the amount of tweets to receive!  It also shows you how to create a google map using the export to kml function. So here’s an updated map with a full 100 tweets.  Note that a lot of them overlap because people have their location set to a city and not a set of coordinates. 

In fact, almost half of these tweets are about a watermain break in Toronto re-tweeting that “Subways are bypassing Union Station due to severe watermain break that is flooding the station”. This is in part due to the fact that Toronto’s twitter users have started using twitter to provide real-time updates on the status of Toronto’s public transit.

Try clicking the “view larger map” link so you can cycle through the tweets to see the overlapping ones.

While we’re at it, let’s try a few other search terms!


World Water Day Tweet Map

This one’s a bit more spread out.  Still focused a lot on the United States.  My guess is that this is a result of a skewed user base and language differences, not the actual publicity for World Water Day.  This map is probably more representative!

Any other great ideas for a tweet map?  Leave them in the comments!

Your maps are awesome! Too bad we can’t train people to use a specific hashtag to report a water main break. Then you would just have to search for that.
