Digital Terrain Modelling : Development and Applications in a Policy Support Environment
This book presents a set of papers on Digital Terrain Modelling for Policy Support which aims to be informative and stimulating for both developers and users of digital terrain models. It should also be useful for professi- als who are interested in the wider aspects of the applications of terrain models in support for policies and decision making. There is an increasing demand for regional and continental scale data for use in environmental modelling and spatial analysis to support envir- mental policy development and implementation. Important environmental processes act at regional and continental scales, for example climatic change inducing floods and soil erosion, and management of these pr- esses for the sustainable development of society requires policies to be - plied at the corresponding scales. One of the most important factors inf- encing these environmental processes which act on the earth’s surface is the surface topography, hence the need for extensive, harmonised digital terrain models.
Advances in Digital Terrain Analysis
Terrain analysis has been an active study field for years and attracted research studies from geographers, surveyors, engineers and computer scientists. With the rapid growth of Geographical Information System (GIS) technology, particularly the establishment of high resolution Digital Elevation Models (DEM) at national level, the challenge is now focused on delivering justifiable socio-economical and environmental benefits. The contributions in this book represent the state of the art of terrain analysis methods and techniques in areas of digital representation, morphological and hydrological models, uncertainty and applications of terrain analysis.
