Diploma in RS and GIS
Remote Sensing (RS) deals with the use of Satellite images and their analysis for providing up to date information of surface features. The most useful characteristic is the multi spectral and temporal resolution of the data. That is, images are obtained in different portions of the electromagnetic spectrum and the same area is imaged with a specified periodic time interval. Remote Sensing has been traditionally used for study of natural resources. With improved technology in the sensors, finer resolution of the ground data has been possible. Therefore RS is now being used to create base maps for GIS applications.
Geographic Information Systems (GIS) is a technology, which enables the analysis of data related to entities, which have geographic distribution. The relationship between distributed entities is termed as a spatial relationship. GIS helps in undertaking spatial analysis and is therefore applicable to a wide variety of disciplines. In recent times GIS has found acceptance among many organizations who wish to use this technology to optimize their daily operations and provide better service to their customers.
RS & GIS are increasingly being used to monitor the natural resources, mining, telecommunications, Utilities, Ground water assessment, Linking of rivers, National agriculture Atlas, state/district level crop yield estimation etc. besides several ongoing national and state level projects. These applications form a direct input in preparing national policies. RS & GIS can also be used to monitor the effect of environmental management techniques in adhering to global norms.
The subject of Remote Sensing (RS) and Geographic Information Systems (GIS) encompasses several disciplines and it is this interdisciplinary nature of the technology that sets it apart from other technologies. This is evinced from its wide applications in varied disciplines and faculties, Geosciences, Biosciences, Life sciences, Environmental sciences, Physical sciences, Hydrology, Engineering applications, Rural and Urban planning, Land cover/ Land use, Agriculture, Soil mapping, Medical sciences, Information technology, Retail mapping, Library Information systems, Wildlife habitats, Wetland mapping, Utilities (Telecommunications, Electrical, Hydro,), Business Decisions, Facilities Mapping, Asset Management etc
Socio-Economists use it to analyze demographic data from a spatial perspective. Ecologists, Biologists and Environmental Scientists study habitats and climatic phenomena. Geographers and Urban Planners derive developmental plans and predict future growth. Earth Scientists use it in mineral exploration and natural resources. Retail and Distribution Agencies use it to map their distribution network and to optimize logistics leading to higher efficiency and lower costs. Law Enforcement Agencies study crime patterns and develop more effective remedial measures. Rehabilitation Organizations map the effects of natural disasters to plan their relief operations. Agriculturists effectively use it to evaluate cropping patterns and derive maximum yield. Life Scientists study the pattern of incidence of diseases to find the causative factors and initiate preventive measures.
Together RS and GIS provide a formidable means of addressing many problems affecting the day-to-day life of mankind.
Thus we see that RS and GIS have far reaching implications in many spheres of activity impacting the whole of mankind.
