Today computer systems have found vast applications in various fields, including preparation of maps and analysis of descriptive and spatial information. Geographic Information Systems (GIS), as computer systems utilizing modern software and hardware facilities, have been able to present remarkable services in collection, analysis and display of information. In this regard, the Global Positioning System (GPS) is of greater importance as one of the most important sources of providing information for GIS. In this paper, the author has tried to raise major questions regarding the precision of collected data through GPS/GIS, and to discuss the qualities of spatial and characteristic data in different aspects.
