Detection and extraction of mining-induced ground deformation can be used to understand the deformation process and space distribution and to estimate the deformation laws and trends. This study focuses on the application of ground deformation detection and extraction combined with digital surface model (DSM), derived from China’s ZiYuan-3 (ZY-3) satellite stereo imagery and the advanced spaceb...

This paper analyzes the relationships between northwest flow snowfall (NWFS) and various topographic and geographic (TOPO/GEOG) variables in the Southern Appalachian Mountains of the southeastern U.S. We identify NWFS events on the basis of low-level wind direction, extract values for the TOPO/GEOG variables from Digital Elevation Models (DEMs), and develop statistical relationships between NWF...

This paper describes a method to automatically construct a 3D geometric model of an urban area by merging features extracted from a cadastral map of the area and from the corresponding digital elevation model (Dem). The cadastral map and the Dem are both transformed into two sets of contour segments: The segments extracted from the map represent contours of buildings and blocks of buildings, wh...

„Agile Software-Entwicklung“ bezeichnet eine iterative Vorgehensweise, die sowohl in Silicon Valley Startups als auch großen Software-Häusern erfolgreich eingesetzt wird. Musste nach dem Wasserfall-Modell jede Eventualität im Voraus akribisch bedacht werden, sind agile Ansätze deutlich flexibler: In kurzen Zyklen wird eine einfache, prototypische Lösung zum vollwertigen Produkt ausgebaut. Am En...

The technique of Interferometric Synthetic Aperture Radar can generate high precise Digital Elevation Model (DEM) fast, which makes it play a very important role in the development of social economy and construct of national defense. Once the high precise DEM can be acquired in real-time, the worthiness of the technique will be embodied fully. In this thesis, the research dynamic of generating ...

The 2008 Wenchuan earthquake and associated co-seismic landslide was the most recent expression of the rapid deformation and erosion occurring in the eastern Tibetan Plateau. The erosion associated with co-seismic landslides balances the long-term tectonic uplift in the topographic evolution of the region; however, the quantitative relationship between earthquakes, uplift, and erosion is still ...

Traffic simulation systems are widely used for the prediction of certain effects like traffic jam formation or the analysis of performance for new traffic light systems. Fuel consumption and CO2 emissions are important measurements. This work integrates a physical model for fuel consumption into a microscopic traffic simulation system for urban scenarios. The parameters of the model are discuss...
