  • Call for Papers on “Urban Geoinformatics”

    We are currently guest-editing a special issue on “urban geoinformatics” in the Taylor & Francis journal “Geo-Spatial Information Science”. On this occasion, we’d like to encourage you to submit your crowdsourcing-related work emphasizing urban issues: Title: Crowdsourcing for Urban Geoinformatics Deadline: 30 October 2017 Guest editors: Hongchao Fan, Wuhan University, (hongchao.fan@whu.edu.cn) João Porto de Albuquerque,…

  • Study “Multiscale analysis and reduction measures of urban carbon dioxide budget based on building energy consumption” published

    The 3D spatial data processing group had the opportunity to collaborate with the team of Prof. Tzu-Ping Lin from National Cheng Kung University, Tainan, Taiwan, within the frame of a study dealing with carbon emission reduction measures in urban environments. One option of reducing carbon emission by buildings is to install photovoltaic (PV) panels in…

  • Determination of building inundation depths based on user-generated flood images – new study published

    In our recently published study “Direct local building inundation depth determination in 3-D point clouds from user-generated flood images” we present a new approach for deriving local building inundation depth from ordinary user-generated flood images captured during a flood event. After reconstructing a 3-D scene of the building of interest with close-range photogrammetry (CRP) algorithms,…

  • 3D bathymetry measurements in shallow-water environments with a low-cost sensor – study published

    To take bathymetric measurements in areas with shallow water is very challenging for methods such as SONAR or bathymetric LiDAR. In our study “Assessing the Potential of a Low-Cost 3-D Sensor in Shallow-Water Bathymetry”, we examine the performance of a low-cost 3D camera when capturing bathymetry in waters up to 0.4 m depth. The tested…

  • Are Crowdsourced Datasets Suitable for Specialized Routing Services? Case Study of OpenStreetMap for Routing of People with Limited Mobility

    Using data generated from the crowd has become a hot topic for several application domains including transportation. However, there are concerns regarding the quality of such datasets. As one of the most important crowdsourced mapping platforms, in a recent study (1) we analyze the fitness for use of OpenStreetMap (OSM) database for routing and navigation…

  • 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…
