  • Overview Article on Online Participation in Geoinformation Technology, esp. OpenStreetMap

    An invited introductive overview article on “Online Participation in Geoinformation Technology” with a specific focus on OpenStreetMap has been published in the special issue “Online Participation” of the German language journal “Praxis der Wirtschaftsinformatik”. It gives some introduction and selected examples of potential usages of OSM data. Griesbaum, L., Eckle, M., Herfort, B., Raifer, M.,…

  • GIScience @ ISCRAM 2017

    The last couple of days, the picturesque city of Albi in southern France became the gathering place of researchers, practitioners and organizations in the field of information systems for crisis response and management. Following the ISCRAM conference theme “Agility is coming” presentations, round tables, workshops, symposiums and keynotes were organized in which the current and…

  • Last Call for Papers on VGI-ANALYTICS – Special Issue in Geo-Spatial Information Science

    Geo-spatial Information Science Special Issue Call for Papers on Volunteered Geographic Information (VGI)-Analytics Deadline: 9 June 2017 Geo-spatial Information Science (GSIS) invites you to submit your paper to this forthcoming special issue on: Volunteered Geographic Information (VGI)-Analytics. ​ Aims and Scope Volunteered Geographic Information (VGI) and social media data have become part of our everyday…

  • Monitoring and Assessing Post-Disaster Tourism Recovery Using Geotagged Social Media Data

    Tourism is a economically highly important industry. It is, however, vulnerable to disaster events. Geotagged social media data, as one of the forms of volunteered geographic information (VGI), has been widely explored to support the prevention, preparation, and response phases of disaster management, while little effort has been put on the recovery phase. A recently…

  • ISPRS Best Paper Award on human activity patterns for Dr. Wei Huang

    Recently the paper “Understanding human activity patterns based on space-time-semantics” by Wei Huang, and Songnian Li (Ryerson University, Toronto, Canada) has been selected as the best paper published in 2016 (volumes 111-122) in the ISPRS Journal of Photogrammetry and Remote Sensing. Dr. Wei Huang is since late 2016 team member of the GIScience Research Group.…

  • Utilizing crowdsourced data for studies of cycling and air pollution

    Recently, Strava, a popular website and mobile app dedicated to tracking athletic activity (cycling and running), began offering a data service called Strava Metro, designed to help transportation researchers and urban planners to improve infrastructure for cyclists and pedestrians. Strava Metro data has the potential to promote studies of cycling and health by indicating where…

  • Towards evaluating the mobile crowdsourcing of geographic information about human settlements

    Geographic information crowdsourcing is an increasingly popular approach to derive geographic data about human settlements from remotely sensed imagery. However, crowdsourcing approaches are frequently associated with uncertainty about the quality of the information produced. Although previous studies have found acceptable quality of crowdsourced information in some application domains, there is still lack of research about…

  • A graph-based strategy for matching points-of-interests from different VGI sources

    Several urban studies have been increasingly relying on spatial data provided by Volunteered Geographic Information (VGI) sources. The matching of features across different VGI projects may serve to assess and improve the reliability and completeness of VGI data. In a recent study, we first provide a short discussion on the similarity measures often used for…

Authors are requested to follow the formatting guidelines for short paper submissions on the AGILE 2017 call for papers page and use the  Word .doc template or the  Word .docx template provided. Short papers should be…

  • A Framework of Quality Assessment Methods for Crowdsourced Geographic Information: a Systematic Literature Review

    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.…

  • Towards using Volunteered Geographic Information to monitor post-disaster recovery in tourist destinations

    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…

  • Completeness of Citizen Science Biodiversity Data from a Volunteered Geographic Information Perspective

    Observations of living organisms by citizen scientists that are reported to online portals are a valuable source of information. They are also a special kind of volunteered geographic information (VGI). VGI data have issues of completeness, which arise from biases caused by the opportunistic nature of the data collection process. We examined the completeness of…
