碩士 === 國立海洋大學 === 航運技術研究所 === 87 === Geographic Information System is a computer system used for the acquisition, storage, compilation, processing, analysis and presentation of geographic information. In real world, nearly all conditions are related to space and location. Following the rapid progress of computer technology, geographic spatial information naturally should not be absent in the overall computerization. In this research project, a geographic information system called NAVigation GIS, or NAVGIS, will be developed as a demonstrator of a central navigation information provider and a platform for data exchange and sharing . The information provided in NAVGIS may be static information retrieved from databases, real time weather or sea forcast data or results of composite information analysis. Electronic navigational charts of the inshore waters around Taiwan and Kaohsiung Harbour areas for harbour and harbour approach will be digitized as GIS map files and treated as a vertical database. Besides the chart information, database of accidents and navaids will be integrated (geo-coded). Possible applications of this NAVGIS include general navigation information service, risk warning / vunerable area, marine transport planning, accident database analysis, management of navigational aids database, harbour service and VTS, marine search and rescue, maritime research and education. An Internet server is developed for realizing resource sharing by linking internet technology, it’s called internet GIS, or IGIS. The query and analysis functions of the NAVGIS will be developed for the above applications on GIS.
