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…

The emergence and evolution of OpenStreetMap: A cellular automata approach
Collaborative mapping projects, such as OpenStreetMap (OSM), have received tremendous amounts of contributed data from voluntary participants over time. So far, most research efforts deal with data quality issues, but the OSM evolution across space and over time has not been noted. Therefore, a new study is dedicated to the evolution of the contributed information…

3D-LiDAR and GIS for Gully Detection in Peru
Cushion peatlands are typical features of the high altitude Andes in South America. Due to the adaptation to difficult environmental conditions, they are very fragile ecosystems and therefore vulnerable to environmental and climate changes. Peatland erosion has severe effects on their ecological functions, such as water storage capacity. Thus, erosion monitoring is highly advisable. Erosion…
