Ohsome - eine Plattform zur Analyse raumzeitlicher Entwicklungen von OpenStreetMap-Daten für intrinsische QualitätsbewertungenOhsome - An OpenStreetMap History Analytics Platform for Intrinsic Quality Assessments

The Ohsome-platform allows one to analyze the full-history of OpenStreetMap (OSM) worldwide on a temporal resolution of one second. Thus, it enables the quality assessment of OSM through the data itself based on its historical development. In order to serve different user groups, the platform provides interfaces at three different levels of abstraction. The functionalities and possibilities of the Ohsome-platform are illustrated by means of two examples: a web-dashboard to analyze the OSMactivities in Nepal and an analysis of the completeness of house numbers in Africa.
