  • 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…

  • Stellenausschreibung für Studentische Hilfskraft für Online-Umfragen / Webentwicklung

    Das Heidelberg Center for the Environment (HCE) verfügt über zahlreiche inhaltlichen und methodischen Kernkompetenzen im Bereich „Umwelt“ an der Universität Heidelberg. Diese sollen über einen Online-Fragebogen systematisch erfasst und anschließend auf einer interaktiven Webseite visualisiert und zugänglich gemacht werden. Für die technische Umsetzung der Online-Umfrage zur Datenerfassung und für die graphische und dynamische Darstellung der…

  • Introducing the ohsome OSM History Analytics Platform

    The big spatial data analytics team at HeiGIT is currently developing the ohsome OpenStreetMap history analytics platform. Our aim is to make OSM’s full-history data more easily accessible for various kinds of data analytics tasks on a global scale. OpenStreetMap (OSM) is a freely available map of the world to which everyone may contribute geographic…

  • 3D micro-mapping: Towards assessing the quality of crowdsourcing to support 3D point cloud analysis

    Crowdsourcing has been widely applied to extract information from 2D geodata sources such as satellite imagery. In this new study published in the ISPRS Journal of Photogrammetry and Remote Sensing we apply this technique to the growing field of 3D point cloud analysis. This work has been conducted in our 3D-MAPP Project which was funded…

  • Trace element partitioning in fluvial tufa reveals variable portions of biologically influenced calcite precipitation

    Freshwater tufas are widespread phenomena in karst environments denoting important terrestrial paleo-environmental and paleoclimate archives. Additionally, many tufa sites are UNESCO world natural heritages, which emphasizes their societal importance (e.g. Jiuzhaigou, China; Plitvice, Croatia) and the demand for comprehensive conservation and monitoring strategies. Formation of tufas is controlled by numerous factors. The latest publication –…

  • Barrierefreier Routenplaner: neue Daten für Rollstuhlrouting in Heidelberg

    Wie komme ich als Rollstuhlfahrer am besten vom Marktplatz zur Stadthalle? Und welche Wege ohne Hindernisse bieten sich für Eltern mit Kinderwagen durch die Altstadt an? Ein neuer Routenplaner auf Basis von openrouteservice.org soll künftig barrierefreie Wege in Heidelberg aufzeigen, zunächst in der Altstadt und in Bergheim. Seit Dezember 2017 arbeitet die Stadt Heidelberg in Kooperation…
