3D micro-mapping: Towards assessing the quality of crowdsourcing to support 3D point cloud analysis
Crowdsourcing has been widely applied to extract information from 2D geodata sources such as satellite imagery. In this new study published in the ISPRS Journal of Photogrammetry and Remote Sensing we apply this technique to the growing field of 3D point cloud analysis. This work has been conducted in our 3D-MAPP Project which was funded…

OSMlanduse.org + Remote Sensing = New conterminous land use data set for Germany released – filling gaps in OSM through machine learning
Land use data created by humans (OSM) was fused with satellite remote sensing data, resulting in a conterminous land use data set without gaps. The first version is now available for all Germany at OSMlanduse.org. When human input (OSM data) was absent a machine generated missing land use information learning from human inputs and using…

Deep Learning with Satellite Images and Volunteered Geographic Information
Recently, deep learning has been widely applied in pattern recognition with satellite images. Deep learning techniques like Convolutional Neural Network and Deep Belief Network have shown outstanding performance in detecting ground objects like buildings and roads, and the learnt deep features are further applied in some prediction tasks like poverty and population mapping. On the…

GIScience/HeiGIT support to #Mapthedifference
GIScience/HeiGIT and disastermappers heidelberg have been proud supporters of the Humanitarian OpenStreetMap Team (HOT) for a couple of years already. Our GIScience/HeiGIT Team is contributing OSM related research, applications and services. The disastermappers furthermore organize mapathons, workshops and webinars, and thereby help to extend the mapping community and raise awareness about OpenStreetMap (OSM), possible applications…

HeiGIT/GIScience partnership with Kathmandu Living Labs
Kathmandu Living Labs– a team of young entrepreneurs and out of the box thinkers that change the use and creation of data in Nepal. The team around Nama Budhathoki was launched in 2013 and emerged of a previous Open Data for Resilience Initiative (OpenDRI) program. In the scope of the OpenDRI project, the team has…

The impacts of environmental factors on cycling behavior
As it is widely accepted, cycling tends to produce health benefits and reduce air pollution. Policymakers encourage people to use bikes by improving cycling facilities as well as developing bicycle-sharing systems (BSS). It is interesting to investigate how environmental factors influence the cycling behavior of users of bicycle-sharing systems, as users of bicycle-sharing systems tend…

GIScience welcomes New Master Students
Yesterday, GIScience Heidelberg was welcoming our new master students. After a general introduction into our teaching philosophy, our core courses and our institutes (HeiGIT, HCE, IWR), we were giving insights into the specialization in GIScience/Geoinformatics, which is possible in the Geography Master Programme. As our teaching is research-based and research-oriented we were presenting most recent…

The OpenStreetMap folksonomy and its evolution
The comprehension of folksonomies is of high importance when making sense of Volunteered Geographic Information (VGI), in particular in the case of OpenStreetMap (OSM). So far, only little research has been conducted to understand the role and the evolution of folksonomies in VGI and OSM, which is despite the fact that without a comprehension of…
