  • New research project: 4D Near Real-Time Environmental Monitoring (4DEMON)

    The Ministry of Science, Research and Arts, Baden-Wuerttemberg has funded a new research project called 4DEMON, which will approach the research front of 4D Near Real-Time Environmental Monitoring. Our physical environment underlies permanent changes in space and time with strongly varying triggers, frequencies, magnitudes and also consequences to humans. Monitoring of Earth surface processes (e.g.…

  • Matching GPS trajectories to street segments – an open source implementation

    We would like to inform about a new open source tool that allows matching of GPS trajectories to corresponding street segments. The tool implements a simplified version of the algorithm presented by Zhang et al. (2010). It is a JAVA based implementation and has been put under LGPL license. You can access the source code…

  • 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…

  • 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…

  • MayaArch3D Closing Meeting 4th/5th of June 2015 at DAI-KAAK, Bonn

    The MayaArch3D project held its final closing meeting at the German Archaeological Institute in Bonn from the 4th to the 5th of June 2015. Two days of discussions and presentations demonstrated the results of the 3-year BMBF (German Ministry of Education and Research) funded project “MayaArch3D – A Web-based 3D-GIS for the Analysis of the…

  • Mon-Shieh Yang successfully completes his PhD

    Mon-Shieh Yang successfully defended his PhD thesis at the National Cheng Kung University (NCKU) in Taiwan. We cordially congratulate him! Mon-Shieh was member of the Heidelberg GIScience Team for almost one year (until May 2015). He was performing research with the LiDAR Research Group (LRG) where he investigated the derivation of novel LiDAR-based roughness measures…

  • How to detect post-harvest growth from terrestrial LiDAR point clouds in precision agriculture? Read the new paper about comparative classification analysis

    The new paper “Comparative classification analysis of post-harvest growth detection from terrestrial LiDAR point clouds in precision agriculture” has just been finally released in the ISPRS Journal of Photogrammetry and Remote Sensing. http://dx.doi.org/10.1016/j.isprsjprs.2015.03.003 Citation Koenig, K., Höfle, B., Hämmerle, M., Jarmer, T., Siegmann, B. & Lilienthal, H. (2015): Comparative classification analysis of post-harvest growth detection…

  • History Scanned in 3D – Jupiter Column of Ladenburg

    Within our interdisciplinary collaborative research project MUSIEKE (Multidimensional Perceptibility of Cultural Heritage) the Jupiter Column (“Iupittergigantensäule”) of Ladenburg was scanned in 3D and in very high detail for the first time. Our colleagues from the IWR (FCGL Group of Hubert Mara) performed the measurement campaign. In this report (in German) the SWR 4 radio station…

  • How to combine OpenStreetMap and Airborne Laser Scanning data for updating Digital Elevation Models?

    The answer can be found in our most recent paper “Updating Digital Elevation Models via Change Detection and Fusion of Human and Remote Sensor Data in Urban Environments” that has just been finally released in the International Journal of Digital Earth. You can find a preprint version of the article freely accessible here: http://koenigstuhl.geog.uni-heidelberg.de/publications/2015/Hoefle/Klonner_et_al_2015_preprint.pdf Citation…

  • 2nd. Call for Papers: RICH-VGI Workshop @ AGILE 2015, Lisboa

    2nd Call for Papers: Enriching VGI @ AGILE 2015 Workshop We call for papers for the Workshop: RICH-VGI: enRICHment of volunteered geographic information (VGI): Techniques, practices and current state of knowledge Workshop @ the 18th AGILE Conference on Geographic Information Science Lisboa, Portugal. Tuesday 9 June 2015 In recent years we have witnessed the rapid…

  • Visualising GPS data from OpenStreetMap using WebGL

    GPS data uploaded to the OpenStreetMap servers is a popular example of what is called Volunteered Geographic Information (VGI). The data has been (and is still) collected by the project contributors primarily to support mapping. As the inclusion of roads and paths in the map is a major goal of the project, the collected GPS…

  • New paper published: ‘Effects of Reduced Terrestrial LiDAR Point Density on High-Resolution Grain Crop Surface Models in Precision Agriculture.’

    We are happy to announce that a new paper with the title Effects of Reduced Terrestrial LiDAR Point Density on High-Resolution Grain Crop Surface Models in Precision Agriculture has been published in the special issue Agriculture and Forestry: Sensors, Technologies and Procedures in the journal Sensors: 3D geodata play an increasingly important role in precision…
