  • 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…

  • Call for Applications: Research Group GIScience (Kleine Forschergruppe Geoinformatik) and Field Trip (Geländepraktikum / Übung) to Greece

    Location and Dates The field course will take place from 21-29 April 2015 in Greece. Instructors Bernhard Höfle and Martin Hämmerle Rationale The availability and coverage of high-resolution and highly accurate 3D point clouds of the Earth surface, including the terrain surface as well as raised objects on the bare earth (e.g. trees and debris),…

  • Online article in 3D Visualization World Magazine: UNESCO World Heritage Site Lorsch Abbey

    The online magazine 3D Visualization World (www.3dvisworld.com) features an article about the 3D capturing campaigns at Lorsch Abbey: ‘The UNESCO World Heritage Site of Lorsch Abbey is located in Hesse roughly between Heidelberg and Frankfurt/Main, Germany. Laser scanners generating 3D point clouds of the structure and photogrammetric Structure-from-Motion (SfM) approaches were used to study and…

  • Mon-Shieh Yang from Taiwan joins GIScience Team

    Mr. Mon-Shieh Yang, a senior PhD candidate from the National Cheng Kung University (NCKU), Department of Earth Sciences, has been awarded a grant of the National Science Council (NSC) of Taiwan to join the LiDAR Research Group (LRG) of the Chair of GIScience Heidelberg from July 2014 to April 2015. His research will focus on…

  • Successful field trips of the laser scanning course

    This summer semester’s laser scanning course comprises a series of field trips done by small student groups of maximum two persons. Campaign planning and hands-on laser scanning in the field were conducted by the students and supervised by professor Bernhard Höfle, tutor Jörn profe, Kristina König, and Martin Hämmerle. Intensive learning for each single participant…

  • Low-cost 3D sensing of natural objects in the Dechen Cave

    In one of Germany’s most visited show caves, the Dechen Cave near Iserlohn, different objects were captured with the GIScience‘s high-end terrestrial laser scanner Riegl VZ-400 and the low-cost structured light camera Microsoft Kinect™ by Johannes Fuchs, Bernhard Höfle, Martin Hämmerle (LiDAR Research Group) and Andrea Schröder-Ritzrau (Institute of Environmental Physics). Morphometric features that are…

  • Laser scanning campaign at UNESCO World Heritage Site Lorsch Abbey

    On Wednesday, 19th of March, the Kings Hall (Torhalle) facades at UNESCO World Heritage Site Lorsch Abbey were captured in 3D with a terrestrial laser scanner Riegl VZ-400 (provided by the Chair of GIScience) by Martin Hämmerle (LiDAR Research Group). The produced data set consists of about 65 million laser points and will allow for…

  • Fusion of human and remote sensor data in urban environments

    OpenStreetMap (OSM) currently represents the most popular project of Volunteered Geographic Information (VGI): geodata are collected by common people and made available for public use. Airborne Laser Scanning (ALS) enables the acquisition of high-resolution digital elevation models that are used for many applications. Our new study combines the advantages of both ALS and OSM, offering…

  • Digital Geoarchaeology 2013: Laser scanning hands-on workshop with GIScience assistance

    On Saturday, 9th of November, a hands-on laser scanning workshop took place within the framework of the Conference ‘Digital Geoarchaeology – New Technologies for Interdisciplinary Human-Environmental Research‘ (held at the Heidelberg Academy of Sciences and Humanities). The conference organizers Dr. Christoph Siart1) and Dipl.-Geogr. Markus Forbriger2) introduced a group of interested conference participants to terrestrial…

  • LiDAR Research group attends the Workshop on “UAV-based Remote Sensing Methods for Monitoring Vegetation”

    The Workshop on UAV-based Remote Sensing Methods for Monitoring Vegetation was held at the University of Cologne, Germany. Around 120 participants discussed the topics UAVs, Vegetation Monitoring, Hyperspectral Vegetation Analysis, Multispectral Vegetation Analysis, 3D-Approaches, Vegetation Indices, Laserscanning and Stereo Photogrammetry. The LiDAR Research Group, represented by Kristina Koenig, attends the Workshop with two posters, dealing…

  • Sunny field trip of laser scanning course

    On 7th of July, the summer semester’s laser scanning course was on a field trip for capturing a gravel bar of the river Neckar next to Ilvesheim. Apart from the main goal of experiencing ‘real life scanning’, the produced data now is used in various analyses: Based on two other datasets from 2011 and 2012***,…

  • LiDAR Research Group completes multitemporal multisensor data for boosting quality of plant growth models

    On 19th of June, a multitemporal data set of agricultural plants was completed by researchers of the Chair of GIScience‘s LiDAR Research Group in the course of the projects Hyland and ESOB. A field of several grain varieties and fertilization quantities in maximum growth stage was captured in 3D using a terrestrial laser scanner (TLS).…
