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…

Population distribution and Elements at Risk layers for Philippines now available
Knowing where people in need could be in a crisis situation is as crucial as it is difficult. Sometimes the difficulty is just not having a convenient way to display or access extant datasources.As a service to the crisis mappers we supply a Tile Service showing the residential population distribution in the Philipines in 90m…

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…

Do cities make us ill? – new project on PsychoGeoinformatics
To what extend do urban environments put stress on mental health? And how can geographic information and analysis support in discovering the underlying relationships ? These are the core research questions of the new collaboration project “PsychoGeoinformatics”. The project has been accepted as a twinning project of the Center for Scientific Computing (IWR) at Heidelberg…

OSM Residential areas get their scales determined
OSM data have no compilation scale information, so we (Chris Kempf, Pascal Neis, Max Rylov and Andreas Reimer) found an efficient way to calculate scale equivalencies for residential areas. While the paper with the description of our linear-time method is under review, please do check out the visualized results! http://openmapsurfer.uni-hd.de/scale-determinator.html Note: the tile server for…

High Cartographic Quality Label Placement on OSM-based Map
In January 2012 we launched OpenMapSurfer – a web map service with a set of custom layers that are based on geo-data of OpenStreetMap project. The main idea was to present OSM data in a different way by placing emphasis on the cartographic representation of data, namely to enhance the quality of the cartographic lettering…
