Mappable is a blog run by Patrick Stotz and Achim Tack that deals with mapping, dataviz & urbanism.

We’ve founded mappable out of fascination for the rapidly growing possibilities in analyzing and mapping urban dynamics. It's the abundance of geocoded data that nowadays offers unprecedented insights into many aspects of city life.

The sources of the data sets we work with is diverse: user generated / crowd sourced content like on wikipedia or open street map, open data released by governments or even corporate data that's been opened up via an API to developers and the public. Infinite are the ideas for applications and mashups that can be generated by using these data sets. Here are some of the, at least in our eyes, most inspiring projects:

While some of them stand out with precise analytic insights into the structure of a specific city or neighborhood, others simply impress by the beauty of their (map) design.

What we aim for at mappable is to find interesting data sets and show what can be done with methods of data analysis & visualization. We do this as a just for fun side-project to our everyday work and work on a non-profit base. If you have any questions about our work, please don't hesitate to contact us.
