Abstract

Geographic Information System (GIS) is the tool of computer data processing with the aim of collection, storage, management and analysis of geographic (spatial) information. Geographic Information System is basically a database system that has been specially designed for location-based vector data (using geographic coordinates). The collected information can be represented in different ways, such as tables, graphs and maps. Geographic information systems are considered as maps of higher level, and a number of them are regarded as new and interesting maps.
