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 any
In a remote sensing system, receiving and recording of information are done by
sensors contrived in platforms. These platforms may have a variety such as aircraft,
helicopter, satellite and spacecraft, but form both quantitative and qualitative points of
view, satellites play one of the most major roles in remote sensing. One of the most
advantages of remote sensing is to collect information from hardly accessible areas or
dangerous locations. Moreover, sensors aboard satellites and aircrafts can be used in
researches 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 physical
contact with them.
In this article, after a review over the remote sensing technology and geographic
information system, it is tried to use roles, applications and evaluation of the effects of
these two subjects, in the geographical studies.
