Study On Database Construction Of Coastal Zone Of ZheJiang Province

Organization criterion of multi-source data and heterogeneous spatial data conversion are two important aspects in database construction of coastal zone of Zhejiang province. Using Arc/Info for WinNT platform , Oracle and ArcSDE, design and construct coastal zone database system of ZheJiang province which has resolved this two problems. The construction of database system will provide the foundation of data loader of new data which will be acquired in the new turn of offshore investigation.Construction of costal zone database of Zhejiang province realize data collection and data integration about Zhejiang's costal zone. It not only provide the function of query, search, update and classify feature of resource and environment, but also dealing with remote sensing image. The database construction is useful to Zhejiang offshore integrated investigation, evaluation and construction of "digital ocean".Costal zone database includes several data of coastal zone such as basic map, important base data and interpretative results. Data processing define organization model of data. It can realize heterogeneous spatial data conversion with little loss and maintain integrality and consistency of vector and raster data. And it also can realize reading and writing data in database conveniently. For the farther step, it can support high-level tools and development of application model by using Arc/Info as client and it also make users to get more interaction when they manipulate the application system.
