Whats are some real time data sources?
I'm working on a demo on real-time visualization and I'm trying to think out of the box. Looks like any big data real-time demo is on twitter or traffic data. Are there any other options out there that publish real-time data (for free)?
Thanks
Answer
Just some thoughts:
Environmental Datasets
As stated by the other comment, have a look to weather, forecast (or similar services).
Space data
What about data from the Universe?
Flights
Here's some real time flight tracking data: the evaluation plan is limited but free.
Social Networks
Twitter Streaming API, Facebook RealTime Updates API (in case you hyave already an app on the social Network), Foursquare
Energy production
Various energy production (real-time and quasi real-time) data.
On these ones probably you have to fiddle around the pages to track the sources of the data, sorry.
Website traffic
Google Analytics RealTime API (for your registered websites)
Money
Bitcoin transactions, Stock Market API
More?
And here and here an "not-so-updated" list of other Real-Time API services (some free, some others not).
