  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.

  In recent decades, we have witnessed an increase in the population of the cities of the country; this increase in population in cities has caused the need for more day-to-day services. Perhaps there are not many service centers in a city, but what matters is the optimal distribution of these centers. Centers of service are one of the service centers that play a major role in the municipality and the guarantor of greater safety for human life. The rapid and timely access of firefighting vehicles to the accident site is very important because the timely delivery of these vehicles to the accident site causes less damage, on the other hand, when it comes to reaching the accident site, the optimal distribution of fire stations is returned. In order to assess the current status of fire stations in relation to fire accidents, the city of Kazeroun was selected as a case study in this study. Then, using GIS functions, network analysis and Tisen polygon analysis, the status of the fire stations in the city of Kazeroun After identifying the inappropriate distribution of these stations using the AHP model and overlapping of indices in the GIS software environment, a suitable location for the fire stations in the city of Kazeroon was identified. The method of this research is descriptive-analytic. The required information was obtained through field observation, studying the plans in relation to the city of Kahrizerun and the map of 2000/1 of this city. Manuscript profile
