Within the 3D-MAPP project we currently developed a workflow and a web based tool, that allow volunteers (and experts) to classiffy 3D point clouds in just a few seconds. The approach combines the point cloud interpretation skills of humans and the scalability of crowdsourcing. Furthermore, crowdsourced geographic information can be of high value to automated [...]

From April 5th till April 9th , the three GIScience members Bernhard Höfle, Kristina Koenig, and Martin Hämmerle visited colleagues at the National Cheng Kung University (NCKU), Tainan, Taiwan, within the frame of the collaboration and exchange project 3D-TAIGER (’Multi-Source 3D Geoinformation Extraction for Improved Management of Forest and Natural Hazards – Collaboration between TAIwan [...]
At Thursday, 22nd of October, the GIScience LiDAR Research Group (LRG) contributed to the workshop ‘The future courtroom‘ (website in German) with a talk introducing the analysis of 3D Geodata and the connections to forensic science. Martin Hämmerle presented a selection of LRG projects covering a wide range of applications and use cases, from crowd [...]
Malnutrition is a challenge to the health and productivity of populations and is viewed as one of the five largest adverse health impacts of [...]
At Thursday, 2nd of July, Martin Hämmerle from the GIScience LiDAR Research Group gave a talk at the Geography colloquium series of the Heidelberg University of Education. Entitled ‘3D Geodata - Background and Application’, the talk introduced basics about 3D geodata and gave a broad overview to research projects of the chair of GIScience. The [...]
With the Geo-reCAPTCHA we present a new concept for crowdsourcing of vast amounts of geoinformation by micro-mapping tasks.
The paper can be downloaded free of charge (until 22 May 2015).
In our study we investigated the possibilities and limitations of capturing building footprints via Geo-reCAPTCHA based on remote sensing imagery. We could analyze more [...]
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 create [...]
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 [...]
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 [...]
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 [...]
