Improving the Quality of Cartographic Labeling
The lettering process, including assigning names to point features, is an essential part of map production. While there have been numerous and varied research efforts to automate point-feature label placement (PFLP), none of them seems to have taken into account the many well-established cartographic precepts for point-feature annotation used by human cartographers. As a result,…

GIS-Based Roughness Derivation for Flood Simulations
Natural disasters like floods are a worldwide phenomenon and a serious threat to mankind. Flood simulations are applications of disaster control, which are used for the development of appropriate flood protection. Adequate simulations require not only the geometry but also the roughness of the Earth’s surface, as well as the roughness of the objects hereon.…

A Review of OpenStreetMap Research
User-generated content (UGC) platforms on the Internet have experienced a steep increase in data contributions in recent years. The ubiquitous usage of location-enabled devices, such as smartphones, allows contributors to share their geographic information on a number of selected online portals. The collected information is oftentimes referred to as volunteered geographic information (VGI). One of…

Qualitätsbewertung nutzergenerierter Geodaten am Beispiel OpenStreetMap
was the titel of a well-attended invited talk at the Geodetic Colloquium in January at the KIT Karlsruhe Insitute of Technology, Geodetic Institute by Prof. Alexander Zipf. It presented some examples of our work on OSM quality assessment such as iOSManalyser, OSMatrix, but also research on transforming OpenStreetMap into 3D. e.g. Barron, C., Neis, P.,…

More than 100 Million Buildings in OpenStreetMap
and therefore also in OSM-3D.org. Just before Christmas the number of building footprints hit the magical number of 100.000.000. “Building” has been for some time now the most frequently used tag defining a map feature in OpenStreetMap. We use the building footprints from OSM to generate an automatically updated special database of 3D buildings displayed…

Mapping land-use from OpenStreetMap
An approach toward generating land-use patterns from volunteered geographic information (VGI) without applying remote-sensing techniques and/or engaging official data has just been published in the latest issue of the International Journal of Geographic Information Science. Collaboratively collected OpenStreetMap (OSM) data sets are employed to map land-use patterns. Initially the spatial pattern of the landscape was…
