                                                                                                                                                    SECTION -I : Remote Sensing : A conceptual framework
                  Concept of Remote Sensing and Geographical Information System (Science) is an integral

               part of geographical studies. Midst of technological development and advancement of science
               and technology,an accurate,orderly and rational information of earth in compliance with its                              Chapter :I      Introduction to Remote Sensing

               different spheres, is of paramount necessity. From the days of ‘Eratosthenes’ during 123 BC to
                                                                                                                                                        What is Remote Sensing
               the contemporary world, Geography has been a subject of dynamism and cognitive idealism.

               The mother Earth endowed/bestowed with mesmerizing horizons of distinct spheres viz.
               Lithosphere, Hydrosphere,Atmosphere and Biosphere. The diversified chores of habitable

               earth needs to be spatially observed and managed for a better with sustainable habitable home.
               A prompt and accurate decision making tools and techniques are need of the hour to expedite

               for a systematic and management per se. In the advent of human civilization through ages
               ,surveying and map mapping technique are of sea change. The prime objective in in the

               middle age (sgsggsgsgssg to hjhjdhjddh) by voyaging through sea route to discover the world
               and resource inventory ,has in many fold, changed to voyage the universe ,especially the earth

               through space .

                    While interacting with the theoretical perspective of Remote Sensing and GIS in general
               and application of Remote Sensing and GIS in geographical studies in particular, there is

               always an urgent necessity to understand the practical aspect. The step by step demonstration
               of data base management using software like ArcGis for both Remote Sensing and GIS has

               been incorporated in this book. Image Processing and Analysis , LULC, NDVI , Thematic
               Mapping by making Shape files, Disease Mapping using IDWI ets are some of the areas which

               are many a times applicable in research of AIO (Area of Interest) .

                   The book is a mare effort to develop theoretical as well as applied knowledge for students
               associated with Geoinformatics. As has been mentioned that this book tells about the very

               fundamentals of Remote Sensing and GIS and therefore ,intentionally or unintentionally,
               some parts having mathematical derivation have been skipped.

                     WE shall be looking forward if this book fulfills the needs of students. For further

               improvement of this book we shall welcome all sorts of suggestions and recommendations
