The internet is full of open and freely available data, as well as the number of available public bikes at railway stations and other verhuurlocaties. That brought the Geodienst of the University of Groningen led to the ov-fietsdata of openov.nl a to add another dimension: time.
The idea came on the rolls after openOV on 13 October, a tweet sent with the statement ‘It has been done! The @NS_online OV-fiets API!’ The tweet referred to a Google Groups conversation, with a link to the uncompressed ov-fietsdata that every 15 minutes is updated. A month later processed in the NS the data itself in its journey planner Xtra app, and since 8 november, users of the app see if there is still a steed to rent. But all of that open data is of course also nice for data research. Or just for creating a nice visualization.
That last did the Geodienst of the BACK. Their visualization not only shows the data clearly on a map, but also adds the dimension of ‘time’. Every five minutes the number of available bikes, to register, you can make beautiful visualizations to be made of the number of available bikes per rental location, something which, according to the service again, it is interesting for students to learn how to deal with data.
The map itself is to be seen in the Geodienst. To the data to visualize, use is made of a javascript api of Arcgis and for the display of the graph uses the site Highcharts. Of course, there is also a Github page of the project.
