Fractal dimension has been found not suitable to be used solely in classifying natural earth terrain. This is due to the fact that surfaces with different texture may portray similar fractal dimensions. Evertsz and Mandelbrot [Evertsz, et. al. 1992] suggested that multifractal dimension may be a more appropriate parameter than fractal dimension in describing geometrical properties of a fractal ...

Nenjiang County experienced intense land use / cover changes during 19852000.The remote sensing and GIS methods were used to find the changes temporally and spatially. The result indicates: the forests were fallen in a large area, from 49.46% to 39.03% of total land area. Simultaneously, the croplands were increased rapidly from 26.02% to 37.42%. The conversion of forests and croplands were the...

Landuse changes that don't follow the principles of land conservation are susceptible to erosion, sedimentation, and flooding. This study aims determine most optimal use scenario in order reduce rate erosion analyse effect change on erosion. research was conducted by collecting rainfall data, soil type maps, slope maps then overlaid using arc GIS calculating value. The simulation is done reduci...

Effective watershed management requires that decision-makers receive input about, and balance consideration of, a number of competing factors. The fundamental drivers of watershed change are modifications to landuse and settlement patterns. To model the effects of landuse and settlement changes properly requires, at a minimum, the ability to model effects related to surface and subsurface hydro...

the relationship between topography, land use, and topsoil moisture storage is investigated for a small catchment with undulating deep loess hilslopes in the south of the netherlands. for a period of 10 months, soil moisture profiles have been measured weekly at 15 locations throughout the catchment. a generalized additive model was employed to find relationships between the various factors inf...

Airborne pushbroom systems for the direct acquisition of digital imagery enable the simultaneous capture of high quality 3D and multispectral information of a scene. The combination of geometric and radiometric information should improve tasks like DTM generation – usually solely based on stereo imagery – and landuse classification, which is traditionally restricted to the interpretation of spe...

Safety of any particular Road way facility cannot be attributed to set of parameters specific to a certain domain. Unsignalized intersections are no exceptions, thus, making them an important area of study. This paper presents the results of the analysis of four parameters, namely road width, traffic control, lane marking and landuse; and their sub-class on the safety of unsignalized intersecti...

The most favorable locations for wind farm were determined based on environmental landuse factors, wind resources and the layout of the electrical grid lines. In the study landuse map was prepared and updated by using Survey of India topographic sheet and ASTER satellite imagery in open source Quantum GIS & GRASS GIS software environment. Wind Power Density Layer was digitized by using Indian w...

Digital elevation models (DEM) of the four catchments were imported into E2, and subcatchment boundaries were delineated. Rainfall surfaces derived from spatial interpolation of ground-based observation data onto a 5 km x 5 km grid was pre-processed to provide a weighted average daily rainfall for each sub-catchment. Data of long term mean monthly potential evapotranspiration (PET) was also use...
