  • This week: Talk by Bastian Entrup

    Another interesting GIScience talk is coming up this week. We cordially invite you to the GIS colloquium: 28.01.15, 11.15am Lecture Hall Berliner Straße 48: “Enhancing IR by Adding Geographical Information: Text- and Geo-based Search within a Corpus of Literary Texts” presented by Bastian Entrup. Feel free to find more detailed information under http://www.geog.uni-heidelberg.de/gis/veranstaltungen.html

  • Visualising GPS data from OpenStreetMap using WebGL

    GPS data uploaded to the OpenStreetMap servers is a popular example of what is called Volunteered Geographic Information (VGI). The data has been (and is still) collected by the project contributors primarily to support mapping. As the inclusion of roads and paths in the map is a major goal of the project, the collected GPS…

  • Call for Papers: Enriching VGI @ AGILE 2015 Workshop

    We call for papers for the Workshop: RICH-VGI: enRICHment of volunteered geographic information (VGI): Techniques, practices and current state of knowledge Workshop @ the 18th AGILE Conference on Geographic Information Science Lisboa, Portugal. Tuesday 9 June 2015 In recent years we have witnessed the rapid emergence of olunteered Geographical Information (VGI) projects. VGI is being…

  • GIScience at the KinderUni: OpenStreetMap for kids

    Children between the age of 9-12 years have the opportunity to attend a practical workshop at the Institute of Geography within the framework of the KinderUni Heidelberg (Young University) on Saturday, 07.02.2015. In this workshop “OpenStreetMap- die offene Weltkarte. Mach’ mit und werde ein Mapper!” the pupils will get to know OpenStreetMap and Citizen Science…

  • Modeling the evolution of OpenStreetMap with Cellular Automata using a new VGI Contribution Index

    Major research efforts have so far dealt with OSM data quality analysis, but the modality of the evolution of OpenStreetMap (OSM) across space and time has been barely noted. Therefore, a new study by Jokar Arsanjani et al. that has recently been accepted for publication in Transactions in GIS aims to analyze spatio-temporal patterns of…

  • In the News: “Urban Emotions” Project

    The DFG research project Urban Emotions was mentioned in an interview of the regional newspaper Rhein-Neckar-Zeitung (in German only). The project aims at the development of a methodology to extract contextual emotional information for spatial planning based on real-time people-as-sensors and crowdsourcing approaches within social media. It is a collaborative project between ZGIS Salzburg University,…

  • Vandalism in Volunteered Geographic Information revisited

    In this weeks BrownBag talk at the UCSB Spatial Center Dr. Andrea Ballatore gave a nice overview about vandalism in user generated geographic information. The talk referred to his recent paper on “Defacing the Map: Cartographic Vandalism in the Digital Commons“. There he outlines a typology of different kinds of map-based vandalism through a qualitative…

  • Special Issue “GeoWeb 2.0” of ISPRS Journal of Geo-Information is Online

    The special issue on “GeoWeb 2.0” of the ISPRS International Journal of Geo-Information with guest editors Alexander Zipf and Bernd Resch (both GIScience Research Group, Heidelberg University) is online and can be found here (Open Access). The special issue aims at exploring new trends in how the production and usage of geographic information are being…

  • Twitter location (sometimes) matters

    In contrast to photo-based VGI (e.g. Flickr) the correlation between the place where an information has been created and what the information is about is less intuitive for text-based VGI. In order to gain more insight into the relationship between text information generated in mobile contexts (e.g. via smartphones) and their recorded location, research has…
