REMOTE SENSING AND GEOGRAPHICAL INFORMATION SYSTEM IN INDIA

ABSTRACT

Geographers have recently expressed need for a greater use of remote sensing methods and GIS, not just in the classroom but also in research projects that are primarily focused on physical geography, though not exclusively. Computers are an essential component of these methods. Only a few exclusive institutions have been able to launch such programmes, and they are progressively adopting these methods in their studies. Geographic information systems (GIS) and digital image processing (DIP) used in conjunction offer improved chances for spatial analysis, environmental monitoring, and forecasting over larger areas in a constrained amount of time. A spatial database of natural resources and a foundation for development plans are provided by such geographic technology. It would be simple to build predictive model skills in the future in order to achieve effective public policy. The development of the local, regional, and national levels is directly impacted by this. A significant technological advance in the approach of gathering data on India’s environment and natural resources has occurred with the introduction of remote sensing. With its distinctive synoptic view, repeating coverage, and dependability, remote sensing has created countless opportunities for spatial mapping, planning, and management to achieve the best possible resource exploitation and conservation. Electronics and the advancement of current information technology have undoubtedly created new opportunities for the sharing and storage of data. Geological, geomorphologic, and environmental hazard mapping, desertification and drought monitoring, and natural resource inventory are all made possible with the help of satellite remote sensing (NNRMS, etc.). It offers a wide range of opportunities to investigate and assess the resources of developing areas. Radar waves and the characteristics of various bands are being used by scientists to conduct hydrological research on soil. Given the current state of the environment, increased industrial growth, and expanding population, effective resource management has become essential.GIS technology and its applications have significantly advanced recently, particularly on the research front. With the development of computer applications and the need to integrate data produced through multiple modes, such as field data, thematic map data, attribute data, and remote sensing data, the use of GIS has grown significantly. As the Sixth Five Year Plan came to a conclusion, the Department of Science and Technology began a project on the Natural Resource Data Management System, which marked the beginning of GIS use in India (NRDMS). To develop, create, and execute a system for better resource management, the expertise available at many top institutions and departments was combined.
