GIS in natural studies

Recently, the necessity of considering natural resources as the basis and foundation for the development of economic infrastructure in developing countries (like ours) has become quite clear. The necessity of decent development and management, allocating facilities, using domestic potentials and knowledge of natural geographical spaces are among the priorities of the country management.
Nowadays, planning has been accepted as the most influential tool in facing complex problems and providing key solutions for managing crisis and allocating facilities. This requires a holistic and complete knowledge of the geographic area on one hand, and integrated, synchronic analysis of all influential elements in that area. This knowledge and analysis needs a system which can store all spatial features in an information bank and represent them according to the needs of the planner in the form of map and information tables.
Geographic Information System (GIS) has been introduced in the last decades as one the most influential planning tools in collecting, analyzing and representing information visualy. The present article seeks to investigate the status and role of information system in different studies on natural resources and its influences.
