Annual Crop Land Information

The annual cropland products were the integrated outcome of the Land use land cover (LULC) output generated at 56m resolution under National Level LULC mapping on 1: 2,50,000 scale using multi-temporal AWiFS project. The study involved use of multi temporal AWiFS data covering Kharif (Aug –Nov), Rabi (Jan- Mar), Zaid (April- May) seasons to address spatial and temporal variability in cropping pattern and other land cover classes.

Broadband Snow Albedo

Broad band Snow albedo is an important geophysical parameter for studies related to weather, climate, and hydrometeorology and so on. Snow has the highest albedo in nature and hence has a significant influence on surface energy budget and on Earth's radiative balance.

Water Bodies Fraction

Water Bodies consists of all surface water bodies viz. reservoirs, irrigation tanks, lakes, ponds, and rivers / streams. The area under water bodies is dynamic in natures and hence multi-temporal satellite data was used for monitoring. An automated extraction algorithm developed is used for quick processing of satellite data acquired from Resourcesat -1, Resourcesat-2 AWiFS sensors (56m spatial resolution) which enables the generation of water body layer.
