Indian Forest Cover Change Alert System using IRS Multi Sensor Data
Forest cover monitoring was initially carried out in 1980s by NRSA and technology was transferred to Forest Survey of India(FSI) and eleven biennial assessments are carried out so far. As per the recent reports, there are some hot spots of deforestation occurring across the year over the entire country. Near real time alert information on forest encroachments, mining, shifting cultivation, and other would help to mitigate damage. In this new initiative, high frequency sub-annual forest cover monitoring is carried out using AWIFS is being standardized with an aim to improve the efficiency and effectiveness of existing forest monitoring capabilities, integrate high temporal medium resolution satellite imagery in forest monitoring andpromote technical cooperation and technology transfer for operational application.
The Study is a joint effort of FSI (MoEnF), NRSC/State Centers/ SFDs in standardizing the methodology, technology transfer and development of an operational system. Approach uses digital comparison of month-wise precision geo-corrected data to deriving alert.
