Amateur or Professional: Assessing the Expertise of Major Contributors in OpenStreetMap Based on Contributing Behaviors
Volunteered geographic information (VGI) projects, such as OpenStreetMap (OSM), provide an alternative way to produce geographic data. Research has showed that the resulting data in some areas are of decent quality, which guarantees their usability in various applications. Though these achievements are normally attributed to the huge heterogeneous community mainly consisting of amateurs, it is…

Better Maps for the Weather Portal Kachelmannwetter
The goal of our new project with Kachelmannwetter.com is to provide specialized maps based on OpenStreetMap data using the cartographic framework MapSurfer.NET which currently serves the map service at uni-heidelberg.de/openmapsurfer. To achieve the project goals, we will design a brand new map style and add several extensions to the framework. Stay tuned for the result!
