Abstract
With rapid development of GIS techniques, GIS techniques have come into applied period in the field of natural science and other application fields. Because of complex marine structure with many dynamic changes, tight relationship among factors in body of water, fuzzy boundary and unintuitive structure character, it is especially difficult to apply GIS to the field of ocean science. Beginning with the ocean current GIS analysis, this paper tries to develop GIS application study of oceanography. It is evident that the first problem needing to be solved is GIS expression of current field. Therefore, main information types of ocean current data that many physical oceanography scientists are using are collected. Firstly, five expression of current field commonly used in physical oceanography are: section vector expression of average current speed, component expression of current field in large area, time series expression of fixed point and expression of current path. The main work of this paper is to give corresponding GIS expression respectively according to the above expressions of ocean current. Based on the above work, corresponding GIS operational cases are given to further prove the feasibility of GIS expressions of current field. Finally, the conclusions and further work are suggested.
