Multi-sensor remote sensing image classification has been considerably improved by deep learning feature extraction and classification networks. In this recent paper, we propose a novel multi-sensor fusion framework (CResNet-AUX) for the fusion of diverse remote sensing data sources. The novelty of this paper is grounded in three important design innovations:

A unique adaptation of the [...]

No place for climate change: A recent transdisciplinary study on the viability of public spaces in cities under increasing heat was featured in the official Heidelberg University Newsroom (English version here).

The study has been conducted by a Heidelberg research team led by Dr. Kathrin Foshag and investigated the heat stress in selected urban squares in [...]

The Humanitarian OpenStreetMap Team (HOT) has announced major financial support from the Audacious Project, which will be provided over the next five years. HOT aims to use this funding to grow OpenStreetMap (OSM) communities in 94 countries. By engaging one million volunteers the goal is to map an area home to one billion people living [...]

Using hospital locations and the ORS Isochrone service, we have created a method for comparing physical access to healthcare in Sub-Saharan Africa. Hospital locations were derived from OpenStreetMap and compared against another free available dataset. Results indicate strong similarity in both hospital datasets, however the uncertainty of our method requires further evaluation.

Today the time has come: The “meinGrün” web app for Dresden and Heidelberg is officially launched.
With the mobile application you can (re-)discover known and unknown green spaces and find a pleasant route to those. Users can learn about the functions of the app via virtual scavenger hunt. The app is the result of the [...]

Accurate and detailed geographical information digitizing human activity patterns plays an essential role in response to natural disasters. Volunteered geographical information, in particular OpenStreetMap (OSM), shows great potential in providing the knowledge of human settlements to support humanitarian aid, while often the availability and quality of OSM remains a major concern. The majority of existing [...]

Transdisciplinary study on climate change adaptation of urban squares
Climate change is not only taking place on distant continents or far into the future, but here and now. In Germany, too, the temperature is rising – and even faster than the global average – and the number of hot days is increasing. Especially in cities, the [...]

We are thrilled to give you a sneak peak into routing with time-dependent road restrictions, the outcome of our collaboration with GraphHopper GmbH in the research project TARDUR supported by the mFUND initiative of the Federal Ministry of Transport and Digital Infrastructure (BMVI) Germany. Our primary focus was on the most common time-dependent restrictions in OSM, namely access [...]

Land use change in Brazil is often associated with a loss of natural habitat (Amazon, Cerrado, Pantanal,…) driven by farmland expansion. A current analysis by a team of Brazilian and German researchers (involving HeiGIT member Sven Lautenbach) shows that for Rio de Janeiro state farmland abandonment has been an important process. Approximately 1 million hectares [...]
