| Remote sensing: Art and/or Science? |
| Science: remote sensing is a tool or technique similar to mathematics. Using a sophiticated sensors to measure the amount of electromagnetic energy exiting an object or geographic area from a distance and then extracting valuable information from the data using mathematically and statistically based algorithm is a scientific activity (Fussell et all., 1986) Art: The process of visual photo or image interpretation brings to bear not only scientific knowledge but all of the background that a person has obtained through a life time. Such learning cannot be measured, programmed, or completlty understood. it is infact that |
