Letten is a place at the Limmat river right behind the ZHdK building (where MakeOpenData is hosted) in Zürich.

The project idea is described here:

http://makeopendata.ch/forum/discussion/5/physical-mashup-of-a-multicolor-led-and-the-current-water-temperature-at-letten-environmental-data

The aim of OpenLetten is to show how hard it is to parse data if the publisher choses to only support the human readable data format (here PDF ), and how easy it becomes to build novel visualisations and mashups once the data is also published in an open, machine readable data format (e.g. CSV or RSS ).
