Abstract

Today there is rarely any applied science or branch of activity on earth that has no need to understanding the environment, geographic position and natural conditions and potentials. Geographic information is the most important decision-making tool in different activities on earth.
The knowledge of mapping (surveying, remote sensing, and geographic engineering) has benefited from the blessings of the glorious Islamic Revolution more than any other science. The dramatic changes and advances that have been made in earth sciences in recent years have been influenced by the need for quick and accurate access to better understanding of the land and potentials of the country in the field of defense and developmental construction.
