High resolution topographic data have the potential to differentiate the main morphological features of a landscape. For the purpose of this study the Digital Terrain Models (DTMs) ranging between 1m and 20m (cell size) were derived from the last pulse LiDAR data by filtering the vegetation points. We tested the effects of different resolutions in the analysis of river morphology, and potential...

Urban planning exerts influences on environmental, social and economic system related with the city. Processes of land transformation and city growth determine radical changes in urban landscape morphology and as a consequence they affect air temperature and energy exchange. The urbanization can bear on local climate more intensively than the global warming does. This is due to the rapidity of ...

introduction  nowadays, landscape recounts the land components, elements and components which each alone and together have a key role in building and shaping the natural environment and consequently the natural landscape and eventually the built environment and landscape. although humans connection with its surrounding is achieved through different senses, but still more than 80% of its connect...

Shape-from-shading and shape-from-texture methods have the serious drawback that they are applicable only to smooth surfaces, while real surfaces are often rough and crumpled. TO extend such methods to real surfaces we must have a model that also applies to rough surfaces. The fractal surface model [Pentland 831 provides a formalism that is competent to describe such natural 3-D surfaces and, i...

We consider the classical Wright–Fisher model with mutation and selection. Mutations occur independently in each locus, and selection is performed according to the sharp peak landscape. In the asymptotic regime studied in [3], a quasispecies is formed. We find explicitly the distribution of this quasispecies, which turns out to be the same distribution as for the Moran model.
