Digital Remote Sensing

Remote sensing has provided a new impetus for the earth, resource and environmental scientists. This gift from the space technology has to be fully harnessed for tackling the problems of the country. Increasing population and diminishing resources have compelled our planners, leaders and scientists to consider better ways for the management of natural resources. Plea for sustainable development has added new dimensions to resource and environmental management. Synoptic view and quick decision making process have become essential to meet the challenges appearing over the national scene. At this juncture, remote sensing technology has come to the rescue. The Indian space programme has provided opportunities for the scientists and technologists to work out strategies in the management of resources. The application of technology obviously required trained man power to take benefit of the opportunities at their disposal. The thematic scientists have to be exposed in their own application areas. Four satellites, specifically for remote sensing (IRS-1A/IB/P2/1D), have been launched. But, it is the responsibility of the scientists to work out methodologies for integrating this latest technology with the traditional and conventional methods which is being practiced in the country over decades. This is perhaps the only way to make remote sensing most acceptable among the decision makers in their own set up. This book has been written with a objective to introduce the remote sensing technology to the application scientists in India. The idea is to provide a comprehensive picture of the scenario of remote sensing in India. This book should be useful to remote sensing scientists and engineers, geographers, geologists, ecologists and environmental scientists, agricultural and soil scientists and urban and regional planners. Regional, state and university remote sensing centres may like to have this book as well.
