NGIS is a national geographic information system. The system incorporates graphic and attribute (text and symbolic) information on ground and underground features, such as topography, geology, hydrology and land ownership, into its database. Units of governments can overlap theme maps to obtain, process and analyze geospatial information based on their administrative demand. Theme maps include transportation networks, locations of addresses, distribution of natural resources, public pipelines, urban planning. NGIS, as it provides information to facilitate government agencies’ management, planning and decision making, has become necessary reference information for use in decision.
