  • Extracting raw GPS data from OpenStreetMap – an LGPL tool

    We are happy to announce that a new JAVA-based tool is available that allows extracting raw GPS data from the OpenStreetMap GPS planet file. The tool is under LGPL license. It allows to specify a bounding box and to export the extracted data to 3D-Shapefiles. Besides the full GPS planet file there are also regional…

  • A Conceptual Quality Framework for Volunteered Geographic Information (VGI)

    The assessment of the quality of volunteered geographic information (VGI) is cornerstone to understand the fitness for purpose of VGI in many application domains. Most analyses focus on the geometric and positional quality, and only sporadic attention has been devoted to the interpretation of the data, i.e., the communication process through which consumers try to…

  • First Arctic Expedition for 3D Earth Observation of Permafrost (Mackenzie Delta, Canada) within our PermaSAR Project

    In June 2015 the LiDAR Research Group (LRG), Heidelberg University, performed a joint expedition with the Alfred-Wegener Institute (AWI). This was our first field expedition within the PermaSAR research project, which is funded by the BMWi / German Aerospace Center (DLR) from 2015 to 2018. The project PermaSAR aims at developing a novel method for…

  • How to find the fastest way out of a dense human crowd using your smartphone?

    In our research “Routing in Dense Human Crowds Using Smartphone Movement Data and Optical Aerial Imagery“, we propose a navigation approach for smartphones that enables visitors of major events to avoid crowded areas or narrow streets and to navigate out of dense crowds quickly. Two types of sensor data are integrated. Real-time optical images acquired…
