Remote sensing has proven to be a powerful tool for the monitoring of the Earth’s surface to improve our perception of our surroundings has led to unprecedented developments in sensor and information technologies. However, technologies for effective use of the data and for extracting useful information from the data of Remote sensing are still very limited since no single sensor combines the op...
While in the field of hydrology remote sensing techniques are often applied and well accepted there is still a deficit in the use of remote sensing techniques in the field of planning, design and operation of water resources systems. It is the aim of this paper to overcome this deficit and encourage water managers to use remote sensing techniques more widely. In order to achieve this, several s...
Spatial Database is a collection of spatially referenced data that acts as a model of reality. Geographical Information System includes spatial data which is either in raster or vector form and data derived from remote sensors are increasingly utilized as source for GIS. Spatial data is the core part of the Geographical Information System. Data mining techniques are studied to discover knowledg...
Remote sensing data and information are shown great potential in supplying relevant spatial data and parameters at the appropriate scale for use in distributed hydrological models for water resource applications. In contrast with many conventional data normally represented by point measurements, remote sensing based measurements are spatially averages over the pixels can appropriate for distrib...
A new aerosol retrieval algorithm is presented which computes the spectral opti-cal depth over the ocean from spaceborne radiometers. It includes both multiplescattering and the bi-directional re ectance of the ocean surface. The algorithmis applied to data from the Along Track Scanning Radiometer 2 (ATSR-2).This radiometer aboard the ERS-2 satellite has 4 bands in the visible a...
assessment of long term erosion and accretion rate of the coastal area is essential for selectionof different types of coastal structures. for example, it is not advisable to develop housing infrastructure onthe coast, which is historically eroding. similarly it is not preferable to select an accreting site for theconstruction of a port in order to avoid annual maintenance dredging after constr...
