The research on water masses is always an important facet of Oceanography. The research adopts the method of Fuzzy Density Clustering to analyse water masses, and uses Visual Basic 6.0 as a developing platform and utilize the MapX components to develop the platform of GIS. By integrating the Water Masses Model compiled by Fortran language, and GIS using Tight Coupling, a integrated system was developed. That makes all phases finished in one condition, including gaining the computing grid, the pick-up and an...
