Paper Abstract

Since the last decade of the past century, GIS has being applied in more and more fields. With the development of the technique, more and more people pay attention to the factor of time, i.e. the new GIS system should be able to analyze spatio-temporal factors in the real world. This paper presents a research project suggesting the use of spatio-temporal techniques as navigation aid onboard ships. Firstly, we analyze the differences of change between the oceanic elements and the land elements. Secondly, we set up a conception system of navigable area. Thirdly, we build up some related mathematical models to take a numerical research, the models are the instantaneous water level model, the triangulation model of soundings, the navigable area creating model and so on. Lastly, by the research, we come to a conclusion that the spatial data includes a lot of information, some of them are well-marked and the others are connotative, by digging the connotative information, some new functions may be developed.
