Cartosat-1 sends high clarity images

Some spectacular images of several countries have been beamed down by Cartosat-1 spacecraft of the Indian Space Research Organisation (ISRO) and they include a riveting pilot’s view of the Khed Brahma area bordering Gujarat and Rajasthan.

The ISRO’s Polar Satellite Launch Vehicle (PSLV-C6) deployed the remote-sensing satellite Cartosat-1 on May 5. According to Rangnath R. Navalgund, Director, National Remote Sensing Agency (NRSA), Hyderabad, the first images sent by the Cartosat-1 on May 7 showed the islands of the Maldives and the satellite beamed down images of the Khed Brahma region the next day. A town called Khed Brahma was situated in the area that lay between Gujarat and Rajasthan.

The three-dimension image showed the area, the range of hills in the region and a river called Harnav Nadhi coursing through the area. There is a temple dedicated to goddess Ambaji and it attracts a lot of devotees. (The published picture does not show the temple).

This particular image was obtained by combining the black and white image of the Cartosat-1, which has a resolution of 2.5 metres and that of the colour image sent by the Resourcesat, whose pictures have a resolution of 5.8 metres, said Mr. Navalgund. This resulted in a colour image. The image had such clarity that it showed harvested fields, haystacks and the boundaries of the field of the Khed Brahma area. A road and a bridge intersecting Harnav Nadhi were also seen. Other images sent by the Cartosat-1 covered Amritsar showing the Golden Temple, the Durgiana temple dedicated to goddess Durga and the Jalianwala Bagh; Tarn Taran area of Punjab, Asuncion, the capital city of Paraguay; Guizhou, in southern China, with its high, rugged plateaus and deeply incised valleys; the Grosseto city of central Italy on the banks of Ombrone river near the Tyrrhenian sea.
