RESOURCESAT-1

Resourcesat-1 satellite is the continuation of IRS-1C/1D mission with enhanced capabilities. The Panchromatic Camera of IRS-1C/1D is improved to multispectral. The WiFS was improved as Advance WiFS (AWiFS) with improved spatial resolution.  
The major objectives of Resourcesat-1:

1.Provide continued remote sensing data services on operational basis for integrated land and water resources management with enhanced multispectral/ spatial coverage and stereo imaging.

2.Develop new areas of applications to take full advantages of increased spatial and spectral resolution.
