OSMatrix— visualizing spatio-temporal characteristics of OpenStreetMap
OSMatrix for Accessibility
This tool provides aggregated statistics of OpenStreetMap data completeness (at attribute level) regarding sidewalk information such as sidewalk width, incline, surface texture and smoothness. The tool is aimed to be used for the assessment of OSM data quality for the purpose of routing and navigation of people with limited mobility (more info: CAP4Access project). The tool is an extended version of OSMatrix.
Extension developed by Amin Mobasheri and Lukas Loos
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 Zipf has been brought to life by Lukas Loos and Oliver Roick at GIScience Research Group at Heidelberg University.
