Constructing Digital Sea of China with the Datum of Coastal Line
Zhou Chenghu · Geo-information Science · 2006
The wave of Earth drives the related research, including those in the field of oceanography. With the development of capacity to acquire the marine spatial data with time serial, Geographical Information System shows its potential in Oceanography because its functions are powerful in spatial data management, spatial analysis and graph or image mapping. Based on the character of marine, a prototype of Digital of China (PDSC) has been constructed with the datum of coastal line of China. With the foundation of PDSC, this paper emphasizes on the problems with their resolutions, which differ from other space digital fields, especially on the data organization and manipulation with the datum of coastal line, the structure of Sea and the integration method, the logic computation and the visualization method.
