Evaluation of any irrigation project involves the assessment of area, improved by the project. Irrigated agriculture will play a major role in determining the future food security of most Asian countries, and it will also be the major contributor to the additional food production required as world population expands. Therefore, it is important to raise the agricultural performance of low produc...

New digital systems for the processing of photogrammetric and remote sensing images have led to new approaches to Ž . information extraction for mapping and Geographic Information System GIS applications, with the expectation that data can become more readily available at a lower cost and with greater currency. Demands for mapping and GIS data are increasing as well for environmental assessment...

Change is one of the many challenges facing fossil resource managers today. This concept is not restricted to physical alterations affecting the resource such as erosion, visitation, vandalism or even preservation. Changes in the views of the public, policies of an administration and in the field of geospatial technology are also greatly affecting how a particular resource program or significan...

   Today, remote sensing technology is used in all scientific and informing fields around the world, and it has achieved to very satisfying results. In the present study, by using remote sensing technology and application of satellite photographs the coefficient of curve number was estimated with high accuracy and pick discharge of the flood was calculated with a good accuracy. In this study, i...

This paper reviews methods and tools of spatial analysis, their integration and application to coastal zone management. Following a definition of the coastal zone and a short description of its peculiarities and unique management problems, the paper first describes the major tools for spatial analysis, and in particular, GIS and remote sensing, spatially distributed simulation modeling and opti...

The management, development and conservation of a protected area require vast knowledge of forest resources, its distribution and utilization pattern by its flora and fauna. Application of remote sensing and GIS as a tool, has assumed immense significance in assessment of these information. These applications are now widely used in conservation and management of protected areas across the globe...

Nowadays the use of remote sensing and Geographic Information System (GIS) is one of the most powerful cost effective tools to identify and discover the available groundwater resources. In this paper, Lithological Units, Lineaments, Slope, Topography, Drainage density, Vegetation and Isohyets lines have been achieved by stations and through remote sensing and GIS techniques. All layers of diffe...

This paper discusses quantitative evaluation of information in remote sensing and GIS data. The formula for calculating information contents of remote sensing imagery are developed, taking into account of signal-noise-ratio (SNR), inter-pixel and cross-band correlations, while information amounts in GIS data are calculated by referring to geometric position, attributes, and the equivocation in ...
