recently we were happy to receive the notification that two new research projects will be funded by the Deutsche Forschungsgemeinschaft (DFG) the German main funding agency for fundamental research.
Both projects belong to the DFG Priority Programme “Volunteered Geographic Information: Interpretation, Visualisation and Social Computing“ (SPP 1894).
The two projects are:

A:) IntrisicOSMquality: A framework for measuring [...]

Volunteered Geographic Information (VGI) has emerged as a potential source of geographic information for different domains. Despite the many advantages associated with it, such information lacks of quality assurance, since it is provided by individuals with different motivations and backgrounds. In response to this, several methods have been proposed to assess the quality of volunteered [...]

The increased development of Volunteered Geographic Information (VGI) and its potential role in GIScience studies raises questions about the resulting data quality. Several studies address VGI quality from various perspectives like completeness, positional accuracy, consistency, etc. They mostly have consensus on the heterogeneity of data quality. The problem may be due to the lack of [...]

On the May 11 and 12, the 8. Dresdener Flächennutzungssymposium (the 8th Symposium of development, monitoring and usages of landuse Dresden) took place in Dresden, Germany. The symposium aims to bring together industry, academy and local government, in order to demonstrate and exchange latest developments in methods, tools and software for the management of landuse [...]

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 [...]

The Conference on Spatial Information Theory (COSIT) is taking place this week in Santa Fe, USA.
This Tuesday our paper on “A Conceptual Quality Framework for Volunteered Geographic Information” by Andrea Ballatore and Alexander Zipf is being presented there.
It outlines new proxy measures to several facets of conceptual quality, including accuracy, granularity, completeness, consistency, compliance, and [...]
