Abstract :
Nature contains a plethora of resources right from the soil, water, and land to various other forms and structures like forest, animals, minerals etc., with the ever increasing demand and exploitation of resources it is mandatory to use it sustainably. The topic “DIP of Natural Mapping” is selected due to the importance of natural resources in every sphere of life in both direct and indirect way right from the use of water to use of soil for food production for very basic need of survival. These resources are being used for this very basic need to various other needs for human. Now it is very important to study and have a very close look of these resources, which are depleting at a very fast rate and hence can be some day come to complete non-existence and thus puts on the question mark on the existence of life on earth. So a complete study, mapping of these resources as well as estimation of its abundance can tell us about its presence, its modes of utilization, its rate of degradation and various measures to conserve it for its sustainable use.Remote Sensing data (aerial & satellite) are applied for mapping and monitoring of various natural resources related with Earth’s surface. Since aerial photograph and satellite image provide a wealth of detail information of a large area of Earth surface as a one time permanent record, inaccessible terrain can be surveyed fairly well. Remote Sensing has proved to be very effective means for developing and integrated GIS, which could meet the challenges of evaluating and managing natural resources. The extent and the amount of resources present, changes in resource, potential, strategy for resource protection and conservation; eco system studies, sustainable use and development practice of natural resources all can be effectively studied by integrated approach with Remote Sensing & GIS. Studies on natural resource management have brought out the basic concept that methods of recovery and use of natural resources are closely interrelated with many human dimensions. The main purpose of this study is to learn the methodology of natural resources inventory of a region and to map them on a suitable scale using Satellite Remote Sensing and Geographical Information System techniques, also to identify various natural resources and to know the methods of preparation of the various thematic maps such as Geology, Geomorphology, soils, forestry, land use, hydrology and the work of man at near the surface of the earth with in a very short time in an economic manner.
