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 [...]

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 [...]
