The data from Indian Remote Sensing Satellites are being extensively and successfully used for a variety of applications towards natural resources monitoring and management. Remote sensing applications in the country have graduated from demonstrative phase to operational phase and expanding their scope to several new areas. Vital applications such as identifying zones which could yield ground water, suitable locations for recharging water, monitoring command areas, estimating crop areas and yields, assessing deforestation, mapping urban areas for planning purposes, delineating ocean areas with higher fish catch potential and monitoring of environment etc., are being pursued actively by users using space based data.
Major application activities using satellite remote sensing data in India are:
|
