Remote sensing satellite: ● It takes imagery of the earth. ● Green area is generally considered as either forests or plantations. So, it is possible to forecast crop production. ● Using imagery information, it is possible to remotely assess an area for landslides. So, statement 1 is correct. ● If patches of green are seen amidst huge bodies of water , that signals presence of phytoplankton (Aquatic Productivity). So, statement 2 is correct. ● It can also be used for finding suitable location for infrastructure projects. So, statement 3 is correct. ● If the image is white , it may be interpreted as ice. So, statement 4 is correct.
