Those tracking kharif paddy, among other scenes, can get a clear picture of it this year, thanks to RISAT-1, the all-weather satellite.
The nation's second radar imaging satellite will be put into orbit at dawn on Thursday.
Its specialty is the SAR or synthetic aperture radar which can see through clouds.
Development and other agencies that track objects, people movements, natural features and disasters on ground using satellite images can now get a round-the-year, all-terrain view of these areas.
