Crowdsourced Classification of 3D Point Clouds
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…

Systematic review of current efforts to quantify the impacts of climate change on undernutrition
Malnutrition is a challenge to the health and productivity of populations and is viewed as one of the five largest adverse health impacts of climate change. Nonetheless, systematic evidence quantifying these impacts is currently limited. Our aim was to assess the scientific evidence base for the impact of climate change on childhood undernutrition (particularly stunting)…

Geo-reCAPTCHA: Crowdsourcing large amounts of geographic information from earth observation data
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 than…

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…
