Less coverage area and high cost per unit area of ground coverage. Example: landsat satellites, indian remote sensing (irs) satellites, Aqua and terra (nasa), and insat satellite series (cid:1) advantages: Large area coverage, less cost per unit area of coverage. Continuous or frequent coverage of an area of interest. Automatic/ semi-automatic computerized processing and analysis. (cid:1) drawback: lower resolution (cid:1) (cid:17)(cid:8)(cid:6)(cid:22)(cid:23)(cid:2)(cid:14)(cid:13)(cid:6)(cid:1)(cid:2)(cid:3)(cid:4)(cid:5)(cid:2)(cid:6)(cid:7)(cid:2)(cid:8)(cid:9)(cid:10)(cid:8)(cid:11)(cid:6)(cid:7)(cid:24)(cid:9)(cid:5)(cid:2)(cid:3)(cid:6) (cid:1) Basic components of an ideal remote sensing system (cid:1) (cid:17)(cid:8)(cid:6)(cid:22)(cid:23)(cid:2)(cid:14)(cid:13)(cid:6)(cid:1)(cid:2)(cid:3)(cid:4)(cid:5)(cid:2)(cid:6)(cid:7)(cid:2)(cid:8)(cid:9)(cid:10)(cid:8)(cid:11)(cid:6)(cid:7)(cid:24)(cid:9)(cid:5)(cid:2)(cid:3)(cid:25)(cid:6) (cid:1) basic components of an ideal remote sensing system. A uniform energy source : provides constant, high level of output over all wavelengths. A non-interfering atmosphere: does not modify the energy transmitted through it. A series of unique energy/matter interactions at the earth"s surface: Generates reflected / emitted signals that are (cid:2) (cid:2)
