OSMatrix— visualizing spatio-temporal characteristics of OpenStreetMap
OSMatrix is a web-based application to visualize characteristics of OpenStreetMap, which are usually not displayed in cartographic representations of the data. The characteristics include information on the topicality of data, user contributions and the presence (or absence) of certain feature types.
OSMatrix is based on an idea of Alexander Zipfand has first been brought to life by Lukas Loos and Oliver Roick at GIScience Research Group at Heidelberg University.
Since Septmeber 2007 you see an improved and enhaced version of OSMatrix, which includes an increased timely resolution (months) and improved user interface with zoomable interactive charts.
This was mainly possible through major changes in the backend, especially the preprocessing component which is now based on the brandnew OpenStreetMap History DB developed by the Big Spatial Data Group of the Heidelberg Institue for Geoinformation Technology (HeiGIT).
The new OSMatrix was made possible through the work of: Michael Auer, Lukas Loos, Rafael Troilo, Martin Raifer, Sabrina Marx. Many thanks to all other people that contributed with their ideas, discussions and valuable advises.
