  • 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…

  • 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…

  • GESIS Top Publication 2017

    One of our recent publications (Bluemke, Resch, Lechner, Westerholt and Kolb 2017) was elected the “top publication 2017” for the research field of “research data management” at the Leibniz Institute for the Social Sciences (GESIS). The paper discusses methodological challenges common to both survey research and GIScience, and is expected to serve as the starting…

  • 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 –…

  • Enrichment of OpenStreetMap Data Completeness with Sidewalk Geometries for Wheelchair Routing

    Tailored routing and navigation services utilized by wheelchair users (such as provided by OpenRouteService.org ) require certain information about sidewalk geometries and their attributes to execute efficiently. Except some minor regions/cities, such detailed information is often not sufficiently present in current versions of crowdsourced mapping databases including OpenStreetMap. In a recent study (1) we aim…

    Call for Papers: ISPRS IJGI Special Issue “Volunteered Geographic Information: AnaLysis, Integration, Vision, Engagement (VGI-ALIVE)” A special issue of ISPRS International Journal of Geo-Information (ISSN 2220-9964). Deadline for manuscript submissions: 30 November 2018 The steady rise of data volume shared on already-established and new Volunteered Geographic Information (VGI) and social media platforms calls for advanced analysis methods…

  • CFP: VGI-ALIVE Workshop at AGILE 2018, Lund, Sweden

    VGI-ALIVE – AnaLysis, Integration, Vision, Engagement Tuesday 12th June 2018, Lund, Sweden, Workshop at AGILE 2018 Introduction to the VGI-ALIVE Workshop The steady rise of data volume shared on already established and new Volunteered Geographic Information (VGI) and social media platforms calls for advanced analysis methods of user contribution patterns, leads to continued challenges in data fusion, and…

  • Highly Cited Paper in Geosciences: Eitel, Höfle et al. (2016)

    Point clouds and our 3DGeo research in Heidelberg are going beyond 3D, such as the new research project Auto3Dscapes. A detailed analysis of this research frontier has been published in Eitel, Höfle et al. (2016): Beyond 3-D: The new spectrum of lidar applications for earth and ecological sciences. The paper has just become a highly…

  • OSMlanduse.org + Remote Sensing = New conterminous land use data set for Germany released – filling gaps in OSM through machine learning

    Land use data created by humans (OSM) was fused with satellite remote sensing data, resulting in a conterminous land use data set without gaps. The first version is now available for all Germany at OSMlanduse.org. When human input (OSM data) was absent a machine generated missing land use information learning from human inputs and using…
