Visualization of Multidimension Oceanographic Data in Geography Information System

Abstract:

The paper presents a solution of designing a combined geography information system(GIS) which can visualize and analyze 2D, 2.5D and 3D vector or raster oceanographic data from the surface, inner, floor and deep of marine in the same view. The Geodatabase geographic data model is benefit to organize, manage and visualize multidimension oceanographic data, therefore it is the best way to use Geodatabase to construct oceanographic database. With the development of combined GIS based on ArcEngine, geometry position of spatial data can be exactly located, in other words,both the planar relation of spatial data and the vertical relation of spatial data can be described, as a result, users can operate multidimension oceanographic data in the combined GIS.

Key words:multidimension oceanographic data; combined GIS; Geodatabase geographic data model
