Abstract

For easy understanding and quick access, all types of geographic information are displayed on maps, because displaying information graphically is, in many cases, more indicative than a number of books on the same matter. Any modification or revision of information in maps requires development of a new map with a process similar to that of the first map. In fact, the information on map is not always exploited and sometimes finds only quantitative value as archives.
