Remote Sensing 07
Remote Sensing 07 : Remote sensing refers to the process of recording information from sensors mounted either on aircraft or on satellites. The technique is applicable to natural hazards management because nearly all geologic, hydrologic, and atmospheric phenomena are recurring events or processes that leave evidence of their previous occurrence. The benefits of the technique are that revealing the location of previous occurrences and/or distinguishing the conditions under which they are likely to occur makes it possible to identify areas of potential exposure to natural hazards. It additionally provides comprehensive displays of disaster information to assess vulnerability, enhance mapping, and monitor. The limitations of the technique include the requirement for expert science writers and graphics designers to translate and package the resulting information into images and explanations that can be easily understood by a wide variety of users; and while space technology has advanced rapidly in recent years, a number of countries still lack the human, technical and financial resources required to conduct even the most basic space-related activities.
