The main purpose of GIS is to prepare and direct special spatial information. In Clarke's view, the GIS mechanism includes software tools that use computer hardware to feed, store, modify, interfere, change, analyze, and finally display geographical data. Furthermore, according to an authority in the field, the GIS process refers to a set of information series and modeling methods that present final results through computer. Therefore, this system, as an internal automated reference, is able to use the provided special information and analyze the results or present them in the form of maps.
