Write a brief answer:

Name the satellites used for observing the earth’s resources.

With the development of technology, new techniques like remote sensing can be used for analysing the change in the stock of natural resources occurring in the world. The depletion and accumulation of resources can be identified from the satellites launched using the remote sensing technology. With this objective, many countries have launched different satellites. France launched the SPOT satellite, USA launched the LANDSAT, Korea launched KITSAT and China launched the Yaogan. India also launched its first remote sensing satellite- the IRS IA in 1988. It also launched many others including IRS- 1B, 1C, 1D, CARTOSAT and RESOURCESAT.
