Intrinsic quality assessment of building footprints data on OpenStreetMap
Recently some of our work on intrinsic VGI quality analysis has been published. In this work we propose a framework to assess the quality of OSM building footprints data without using any reference data. More specifically, the OSM history data will be examined regarding the development of attributes, geometries and positions of building footprints. In…

A Monitoring Tool for OpenStreetMap Mapathons in Python
In the last couple of weeks disastermappers Heidelberg and GIScience members were interested in finding a way to monitor changes in the OpenStreetMap database. This could help to provide better feedback after mapathons and could allow to measure how many objects like buildings or roads were created or modified during a mapathon. (It was even…
