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…

Heidelberg-3D and beyond
was the title of a presentation given at the Smallworld User Meeting in Heidelberg by A. Zipf. It dealt with Spatial Data Infrastructures for 3D data and 3D city models and interoperable ways of visualizing and analysing 3D city models. The examples included Heidelberg-3D.de , OSM-3D.org or OpenBuildingModels.

Towards a Comprehensive Framework for Intrinsic Quality Analysis in OpenStreetMap
As one of the most popular examples of a Volunteered Geographic Information (VGI) project OpenStreetMap (OSM) has more and more become a serious alternative for geodata. Since the quality of OSM data can vary strongly, different aspects have been investigated in several scientific studies. In most cases the data is compared with commercial or administrative…

New WebPortals by GeoNet.MRN – Network, Energy Atlas, etc.
Our “Network Geoinformation of the Metropole Region Rhine-Neckar” has a new updated Web Portal at http://www.geonet-mrn.de. Also the first prototype of the interactive Web-based Energy Atlas http://energie.geoportal-mrn.de/ for the Metropole Region Rhein-Neckar went online already some time ago. Recently our Master Student Sabrina Helsper has developed a Atlas on thermal energy for all of Germany…

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…

About quality assessment for building footprints data in OpenStreetMap
In the past years, several applications of generating 3D buildings from OpenStreetMap (OSM) have been made available, for instance, OSM-3D, OSM2World, etc. In these projects, 3D buildings are reconstructed using the buildings’ footprints and information about their attributes, which are documented as tags in OSM. Therefore, the quality of 3D buildings relies strongly on the…
