  • Open – POI – Service Helps You Find Points of Interest!

    Once again we are extremely excited to announce a new open source project we have been working on over the past few months. To honor the name, we have coined it openpoiservice and it has the simple task of finding points of interest for a given geometry! To this end, it is able to return…

  • Keynote at GISRUK Conference 2018, Leicester

    Prof. Dr. Alexander Zipf is a invited keynote speaker at the 26th annual GIScience Research UK conference (GISRUK) will be held at the University of Leicester on 17-20 April 2018. On Thursday April 18th he will give a talk on “Operationalising Volunteered Geographic Information – From Analytics to Improvement and Application“. Much research has been…

  • Let’s meet at SOTM 2018 :: Paper on OSM History Analytics Accepted in Academic Track

    A paper for the Academic Track of the State of the Map Conference, Milan, has been accepted. We are looking forward to discuss with you following aspects: A growing number of studies analyzes OSM data, its contributors, usage, and quality. Such studies were mostly limited to analyzing either small samples of the OSM database or…

  • Towards Using the Potential of OpenStreetMap History for Disaster Activation Monitoring

    Over the last years, the growing OpenStreetMap (OSM) database repeatedly proved its potential for various use cases, including disaster management. Disaster mapping activations show increasing contributions, but oftentimes raise questions related to the quality of the provided Volunteered Geographic Information (VGI). In order to better monitor and understand OSM mapping and data quality, HeiGIT developed…

  • Graph-based matching of points-of-interest from collaborative geo-datasets

    Several geospatial applications require comprehensive semantic information from points-of-interest (POIs). However, this information is frequently dispersed across different collaborative mapping platforms. Surprisingly, there is still a research gap on the conflation of POIs from this type of geo-dataset. In a recent paper by Novack et al. (2018), we focus on the matching aspect of POI…

  • Third Workshop on “3D Field Methods in Geosciences”

    The third workshop on 3D methods in geological applications was jointly organized by the University of Göttingen, the Geological Service of North Rhine-Westphalia (NRW, German federal state), and the 3D Geo Research Group at Heidelberg University. The workshop is an event of the initiative “3D Field Methods in Geosciences”, which provides a platform to connect…

  • POI/ROI Discovery using Flickr geotagged photos

    In the era of big data, ubiquitous Flickr geotagged photos have opened a considerable opportunity for discovering valuable geographic information. Point of interest (POI) and region of interest (ROI) are significant reference data that are widely used in geospatial applications. A recently published study (Kuo et al 2018) study aims to develop an efficient method…

  • Contribution selected for final round of GISRUK data challenge

    The results of an analysis of migration data and of the Brexit referendum votes are among only four selected finalists of this year’s data challenge associated with the GISRUK conference. The research was conducted by a team advised by Professor João Porto de Albququerque (University of Warwick) including our colleague René Westerholt. The idea of…

  • Preview of the ohsome Nepal dashboard

    The ohsome OpenStreetMap history analytics platform, which is currently developed at HeiGIT, will make OSM’s full-history data more easily accessible. We are pleased to announce that we are coming closer to reaching our objectives, hereby sharing a preview of the first ohsome web dashboard. Our dashboards will allow you to explore OSM full-history data using…

  • Masterclass and Workshop at the University of Warwick

    Our colleague René Westerholt was recently invited to deliver a Masterclass on ‘Spatial Analysis’ at the University of Warwick (UK) on Tuesday, 6th of March. The one-day-event was hosted by the Q-Step Centre, an initiative to strengthen quantiative skills of students enrolled at the Social Science Faculty. The workshop was attended by students from various…

  • ISPRS Education and Capacity Building Initiatives 2018

    The International Society for Photogrammetry and Remote Sensing (ISPRS) is funding scientific and other initiatives, which will further improve its international status in the field of the photogrammetry, remote sensing and spatial information sciences, and will therefore benefit all ISPRS members. For 2018, seven Education and Capacity Building Initiatives projects were selected. GIScience Heidelberg is…

  • Open Positions: Geographic 3D Point Cloud Analysis (Full-time PhD / Postdoc Position)

    Heidelberg University invites applications for one full-time PhD student and one Senior Researcher (Postdoc) for “Geographic 3D Point Cloud Analysis” in the 3D Geospatial Data Processing Group (Prof. B. Höfle) at the Department of Geography. The 3DGeo group is also affiliated with two research centers – the Interdisciplinary Center for Scientific Computing (IWR) and the…
