Many physical, chemical and biological processes taking place at the land surface are strongly influenced by the amount of water stored within the upper soil layers. Therefore, many scientific disciplines require soil moisture observations for developing, evaluating and improving their models. One of these disciplines is meteorology where soil moisture is(More)
Monitoring urban land use requires very high spatial resolution image data, acquired either by airborne or spaceborne sensor systems. The information content of such images is very complex, thus information extraction is currently performed on the basis of visual interpretation. The aim of the research described in this study is to formalise the visual(More)
Roughness is an important input parameter for modeling of natural hazards such as floods, rock falls and avalanches, where it is basically assumed that flow velocities decrease with increasing roughness. Seeing roughness as a multi-scale level concept (i.e., ranging from fine-scale soil characteristics to description of understory and lower tree layer)(More)
In this paper ongoing developments regarding the conceptual setup and subsequent implementation logic of a seamless spatio-temporal population dynamics model are presented. The DynaPop model aims at serving as basic input for social impact evaluation in crisis management. In addition to providing the starting point for assessing population exposure(More)
Interpretation of aerial images is normally carried out by visual interpretation as traditional classification routines are too limited in dealing with the complexity of very high resolution data. Segmentation based classifiers can overcome this limitation by dividing images into homogenous segments and using them as basis for further classification(More)
With the launch of KOMPSAT-2 at the end of 2005 the availability of high resolution data should be greatly improved. The use of download facilities in Europe will allow increased coverage without interfering with the original mission of KOMPSAT-2. With platforms currently under development by the European Space Agency such as the Service Support Environment(More)
The concept of Volunteered Geographic Information (VGI) has progressed from being an exotic prospect to making a profound impact on GIScience and geography in general, as initially anticipated. However, while massive and manifold data is continuously produced voluntarily and applications are built for information and knowledge extraction, the initially(More)
