| Abstract: | The data resources status and information service requirement of hydrography are introduced briefly, the necessity and goal of the construction of hydrographic survey database are also educed. The development items, technology framework and service capability of hydrographic survey database are described totally. The several key techniques are researched deeply, including geospatial database modeling, data classifying storage, common data gathering engine, terrain data precision preserving, huge discrete points gridding, and so on. Lastly, the development route and research goal are reviewed in the future. |
