RESOURCESAT ADDS NEW DIMENSION TO REMOTE SENSING

---

RESOURCESAT-1, launched by ISRO last month from Sriharikota has added new dimensions to remote sensing applications. The three sophisticated cameras on board the satellite were tested for their performance between October 25 and November 5. The imageries generated were processed at the National Remote Sensing Agency at Hyderabad for acquiring data. They were found to be excellent and useful in enhancing remote sensing applications in Agriculture, land and water resources management as well as disaster preparedness and management.

The RESOURCESAT’s unique combination of cameras provided imageries with high spatial, temporal and radiometric resolutions. One camera provided a spatial resolution of 5.8 m and a swath of 23 km in colour and is capable of providing resolution of 5.8 m and a swath of 70 km in black and white. The other one provided a spatial resolution of 23 m and a swath of 141 km. The third camera with a multi-spectral Advanced Wide Field Sansor provided a resolution of 56 m and a swath of 740 km. This unique camera has the capability to take the imagery of the earth every five days with a very high radiometric resolution.

The RESOURSTAT is the most advanced remote sensing satellite built by ISRO so far. It will provide a data quality hitherto not been provided by any IRS-satellites. India’s Remote Sensing System is one of the few most advanced and largest such systems in the world, fully self-reliant both in fabrication and launching capabilities, besides infrastructure.
