Snow cover area is one of the most important criteria to calculate snow melt runoff. This can have an effect on the biology of the plant and the environment of a region. Using the catchment basin physical characteristic to calculate snow cover area is a conventional method, though its accuracy is not good enough. Most of the useful methods in calculating snow cover area are based on satellite i...

Ž A technique using the Hough transform is described for detection of homogeneous line segments directly from i.e., . without binarization of gray level images. A definition of ‘‘region’’ in terms of these line segments, with constraints on its length and variance, is provided. The algorithm is able to extract gray level regions irrespective of their shape and size. The Ž . effectiveness of the...

water plays a vital role in the development of activities in an area. the surface water resources are inadequate to fulfill the water demand. productivity through groundwater is quite high as compared to surface water, but groundwater resources have not yet been properly exploited. keeping this view, the present study attempts to select and delineate various groundwater potential zones for the ...

Very high resolution (VHR) satellite remote sensing systems are now capable of providing imagery with similar spatial detail to aerial photography, but with superior spectral information. This research investigates the hypothesis that it should be possible to use multispectral IKONOS images to quantify urban vegetation, obtaining similar accuracy to that achieved from false colour aerial photog...
