Document Summary
Information about the earth"s land acquired from an overhead one or more regions of the emitted from the earth"s surface. It is the practice of deriving and water surfaces using imaging perspective by employing radiation in electromagnetic spectrum, reflected or. What do we use remote sensing images for: atmosphere, oceans, land area, life on earth. Sensor can be used to obtain specific information about an object or the geographic extent of a phenomenon. The emr reflected, emitted or back-scattered from an object or geographic area is used as a surrogate for the actual property under investigation. The electromagnetic measurements must be calibrated an turned into information using visual and/or digital image processing techniques. Space: design, launch, and maintaint (calibrate) sensor/platform. Ground: receive, pre-process, archive, and disseminate data. User: analyze data, rs scientists develop new generic methods, applications specialist turn data into information to solve real world problems. Passive rs provides an unobtrusive and non-destructive method of studying phenome through time.
