Abstract :
Different explanations have been provided for remote sensing, but as a summary,one can define it as the science and art of information acquisition about objects,terrains or different phenomena by gathering information from them without anycontact.In a remote sensing system, receiving and recording of information are done bysensors contrived in platforms. These platforms may have a variety such as aircraft,helicopter, satellite and spacecraft, but form both quantitative and qualitative points ofview, satellites play one of the most major roles in remote sensing. One of the mostadvantages of remote sensing is to collect information from hardly accessible areas ordangerous locations. Moreover, sensors aboard satellites and aircrafts can be used inresearches about polar territories, upper atmosphere, forest fires, volcanic activities,faraway oceanic parts and deserts which are difficult to be accessed by humans.Actually, remote sensing is the science and art of acquisition of information remotely,that is, obtaining information about objects and phenomena without any physicalcontact with them.In this article, after a review over the remote sensing technology and geographicinformation system, it is tried to use roles, applications and evaluation of the effects ofthese two subjects, in the geographical studies.
