As our HeiGIT / GIScience team member Martin Raifer (tyr_asd) pointed out at his OSM diary, this weekend is the 10 year anniversary of OSM’s API version 0.5. He stresses the importance of this as “This is the version of the OSM-API that introduced (among other things) the version number on all OSM objects, making [...]

DFG Summer School “VGI”
Posted in Crowd Analyser, Events, OSM, VGI Group on Sep 20th, 2017
Last week, our colleagues Franz-Benjamin Mocnik and René Westerholt participated in a summer school of the DFG priority programme on “VGI”. GIScience Heidelberg is involved in that programme by two projects, one of which is dealing with data quality issues and another one that investigates the assessment of spatial assotiations in social media data. The [...]
Reducing stress by avoiding noise with ‘Quiet Routing’ in OpenRouteService
Posted in Crowd Analyser, OSM, Services, VGI Group on Jul 10th, 2017
Noise pollution is a growing problem in many urban environments, affecting citizens’ daily life. It can reduce citizens’ happiness, increase their stress, and even people them get sick if they are exposed to noise pollution for a long period of time. In recent studies we investigate the use of crowdsourced data to derive noise polluted [...]

Since the launch of the MapSwipe Analytics webpage three month ago we were able to improve our service and offer more detailed information on each project in MapSwipe. MapSwipe is a mobile App for crowdsourcing geographic information needed by humanitarian organisations like Red Cross and Doctors without Borders (MSF) introduced earlier. In particular the data can be used for priorizing areas [...]

The set of interactive visualizations “OSMvis” from our GIScience HD team member Franz-Benjamin are now online at: http://osm-vis.geog.uni-heidelberg.de.
Nice work Franz-Benjamin!
OSMvis is a collection of visualizations related to OpenStreetMap (OSM), in particular the OSM database, the OSM wiki, and the use of OSM data in general. OSMvis aims at exploring the generation, modification, and use of OSM [...]
A Framework of Quality Assessment Methods for Crowdsourced Geographic Information: a Systematic Literature Review
Posted in Publications, Research, VGI Group on Mar 12th, 2017
Crowdsourced Geographic Information (CGI) has emerged as a potential source of geographic information for different domains. Despite advantages associated with it, such information lacks quality assurance, since it is provided by different individuals. Several authors have investigated different approaches to assess CGI quality. Some of the existing methods have been summarized in different classification schemas. [...]
Big Data Analytics Panel at the International Workshop on Crowd Assisted Sensing, Pervasive Systems and Communications (CASPer 2017) at IEEE PerCom
Posted in Events on Mar 10th, 2017
Crowd assisted sensing and crowdsourcing, as well as their underlying pervasive systems and communications are a fast growing research area and one of the enabling technologies of smart cities and smart infrastructures, as well as important building blocks in healthcare monitoring and vehicular technologies. Crowd assisted sensing (often called participatory sensing) opens new ways for [...]
Towards using Volunteered Geographic Information to monitor post-disaster recovery in tourist destinations
Posted in Crowd Analyser, Publications, Research, VGI Group on Mar 6th, 2017
The aftereffects of disaster events are significant in tourist destinations where they do not only lead to destruction and casualties, but also long-lasting economic harms. The public perception causes tourists to refrain from visiting these areas and recovery of the tourist industry, a major economic sector, to become challenging. To improve this situation, current information [...]
