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 state-of-the-art [...]

As our HeiGIT / GIScience team member Martin Raifer (tyr_asd) pointed out at his OSM diary, this weekend is the 10 year anniversary of OSM’s API version 0.5. He stresses the importance of this as “This is the version of the OSM-API that introduced (among other things) the version number on all OSM objects, making [...]

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 [...]

In a recently published study (1), we produced a web based land use land cover (LULC) product based on OSM tags which are constantly updated by contributors/volunteers, and present a Remote Sensing based solution when tags were absent for a test site. We harness the combined benefit of an open source and ever-growing machine generated [...]

Last week, our colleagues Franz-Benjamin Mocnik and René Westerholt participated in a summer school of the DFG priority programme on “VGI”. GIScience Heidelberg is involved in that programme by two projects, one of which is dealing with data quality issues and another one that investigates the assessment of spatial assotiations in social media data. The [...]

A recently published paper (Rousell & Zipf 2017) presents a prototype navigation service extending OpenRouteService (Schmitz et al. 2008) that extracts landmarks suitable for pedestrian navigation instructions from the OSM dataset based on several metrics.
In general, when providing instructions on how to get somewhere, people generally include landmarks in their instructions - “Turn left [...]

Noise pollution is a growing problem in many urban environments, affecting citizens’ daily life. It can reduce citizens’ happiness, increase their stress, and even people them get sick if they are exposed to noise pollution for a long period of time. In recent studies we investigate the use of crowdsourced data to derive noise polluted [...]
