Land degradation, or desertification, is specific to arid, semi-arid, and dry sub-humid regions. The rate of thisphenomenon is high in developing countries such as Iran. This research investigated desertification and mapping ofdesertification in Abuzaydabad, near Kashan, Iran, with an emphasis on land criteria using an IMDPA model.Different studies have assessed land degradation or desertificat...

Climate change is amplified in the Arctic, and establishing baseline data for its current character important. Here we present a map of geomorphology Femmilsjøen area, Spitsbergen, northern Svalbard. The regional physiography characterised by low-relief, high elevation mountain plateau, high-relief steep slopes, low-relief coastal lowlands. results indicate that glaciers were most likely warm-b...

The constitution of multi-scale spatial databases is closely linked to map generalisation. Elements of a multi-scale spatial database include multi-scale data models, multi-scale data storage schemes, methods to generate multi-scale datasets and methods to access these datasets and present results. In this paper we proposed a formal multi-scale spatial data model with an information-rich struct...

Interpretation of subsurface geology is greatly enhanced by 3-D seismic data, and this accounts for its ubiquity in today’s search for hydrocarbons. Seismic interpretation has two fundamental disciplines at its core: seismic geomorphology and seismic stratigraphy. Plan views allow the explorationist to apply principles of geomorphology, based on analogies with modern sedimentary systems, to int...

the volume and surface area of the coast is a function of basin water levels. recognizing the factors of coastal geomorphologic changes could have a pivotal role in planning and managing the coast. effective factors in the formation and evolution of geomorphologic factors such as geological, tectonic, paleoclimatic, paleoclimatic and sea level changes have been considered in this study and the ...

A multi-visibility map is the subdivision of the domain of a terrain into different regions that, according to different criteria, encode the visibility with respect to a set of view elements. We present an algorithm for computing approximate multi-visibility maps for a terrain, modeled as a TIN, with respect to a set of view segments. Our approach is based on an algorithm that reconstructs an ...

The capacity of riparian zones to serve as critical control locations for watershed nitrogen flux varies with site characteristics. Without a means to stratify riparian zones into different levels of ground water nitrate removal capacity, this variability will confound spatially explicit source-sink models of watershed nitrate flux and limit efforts to target riparian restoration and management...
