During the last decades, the epidemiological research has given indications that mental diseases including depressions and anxiety disorder can be related to socio-economic, as well as to environmental risk factors. In this project, geodata will be collected and maps showing the potential risk of mental stress in urban environments (urban stress) will be created. The aim is to address the relationship between mental stress and urban characteristics.
In order to address the relationship between mental stress and the urban environment, heterogeneous spatial data has to be collected from a various amount of sources. These include both public and private sources. In addition to that also crowd sourced data will be used. The approach is to first create a homogenous spatial data base that includes relevant socio-economic data (population density, crime statistics, migration- and unemployment ratio etc.) and data regarding the urban environment (noise, air quality, access to public green space, among others). In order to create a homogenous data base, the data from different sources have to be georeferenced, geocoded, transformed, tested for quality and projected in the same coordinate system. Eventually, this will offer a solid database for the study area which incorporates the Rhine-Neckar region, Heidelberg, Mannheim and Ludwigshafen in southern Germany.
The relationship between mental stress and the urban environment will thereafter be addressed by correlating questionnaire data with the spatial urban environment data.Selected Publications:

Understanding how citizens interact with transportation system is a key to solving a variety of urban issues in general and traffic congestion in particular. Recently, scholars have put efforts on the pertinent work ranging from developing traffic predictors to understanding human mobility and activity patterns. Multiple types of data have been used, of which crowdsourced [...]
Fachaustausch Geoinformation DIE JÄHRLICHE NETZWERKKONFERENZ DES GEONET.MRN Vorläufiges Programm und Anmeldung sind nun online. In vielen Bereichen des digitalen Wandels kommt Geoinformation eine tragende Rolle zu. Die zum 10. Mal stattfindende Jahreskonferenz des GeoNet.MRN – der Fachaustausch Geoinformation – nimmt sich dieses Themas an. Die Konferenz findet dieses Jahr am Donnerstag, den 29. November 2018, wie gewohnt, in [...]
Our feature paper “Hyperspectral and LiDAR Fusion Using Deep Three-Stream Convolutional Neural Networks” is now published online. Recently, convolutional neural networks (CNN) have been intensively investigated for the classification of remote sensing data by extracting invariant and abstract features suitable for classification. In this paper, a novel framework is proposed for the fusion of hyperspectral images [...]
Yesterday, the practical field trip in the Erg Chebbi ended and the majority of the group arrived safely in Heidelberg. Another part of the group and the equipment are still on their way back via car and ferry. After several days in the field, we are already very excited to start working on the large amount [...]
We are happy to announce that we are going to be part of INTERGEO 2018 in Frankfurt this week on October 16.-18. This event being the “global hub of the geospatial community” has quite something to offer with hundreds and hundreds of innovative companies showcasing their products and visions. We are joining up with the Federal Agency for Cartography and Geodesy [...]
On Thursday and Friday our group went further into the Erg in order to extend measurements from the last years on a large star dune arm and then spent one night in a dune camp. Yesterday was the last day of field work in the Erg.The TLS group completed the data acquisition on a star dune and [...]
Our paper about Deep Learning from Multiple Crowds: A Case Study of Humanitarian Mapping is available online now. Satellite images are widely applied in humanitarian mapping which labels buildings, roads and so on for humanitarian aid and economic development. However, the labeling now is mostly done by volunteers. In a recently accepted study, we utilize deep learning [...]
During the last three days of field work we not only acquired a lot of data at different sites in the Erg Chebbi. We also experienced various weather conditions including two sand storms, rain and sunny and hot days. Yesterday, one group measured ground control points for satellite and photogrammetric point cloud data with an RTK [...]
Our new ohsome dashboard is another preview on what is and will be possible with our ohsome OpenStreetMap history analytics platform. Behind the scenes, we added support for the Apache Ignite big data framework and deployed an instance using the full OSM history data of whole Germany on Heidelberg University’s cloud computing infrastructure heiCLOUD. Apache Ignite is an open-source [...]
Data acquisition in the Erg Chebbi has now started. In different groups several measurement techniques (drilling, electrical resistivity tomography, ground penetrating radar, sediment analysis, RTK GNSS, terrestrial laser scanning) were applied. Find some impressions in the pictures below.
