With 3-dimensional images of 2.5 metre resolution (i.e. any object which is 2.5 metres in size can be photographed by the satellite), it will be possible to generate digital elevation maps for urban and rural development, land and water resource management, disaster assessment during floods and droughts, relief planning and execution, etc.

Cartosat-1 is the only remote-sensing satellite in the world to carry two B/W cameras and they are mounted for near- simultaneous imaging of the same region from two different angles. The stereoscopic images produced look as if aerially photographed from an aircraft—first of their kind in the world. Besides sending images down to the ground stations where they are decoded, the satellite also carries a solid state recorder which can store 120 gigabits of images.

South Africa, Brazil, Chile and Germany have already made requests to ISRO for images of their countries. Business prospects may even double once Cartosat-2 is launched later this year—taking aerial resolution to as close as 1 metre. In other words, aerial cameras on board Catosat-2 could photograph even a bicycle on earth!
