| Along with the increasing of Spatial Data obtaining means, there have being obtained large amount of the spatial data. How to effectively save, manage and use these spatial data become one of the urgent problem that demand resolve currently.Aiming at the requirement of special application, we present a solution based on Oracle Spatial and ArcSDE. We first analyze spatial database and spatial data engine, study the key technique such as the integration of Oracle Spatial and ArcSDE, multi-source spatial data format conversion, etc. Then we design the architecture of a spatial foundation database prototype system. Finally we implement a spatial foundation database of prototype system.The main work included is as follows:1. Analyzing storage management mode of spatial data, spatial database technique and system.2. We analyze and compare Oracle Spatial and SDE technique. Aiming at the special application requirement, we present a solution to the storage, management and application of spatial foundation data. The solution is based on Oracle Spatial and ArcSDE. Then we design a prototype system with three layer architecture.3. Using Oracle Spatial, ArcSDE, the tools of ArcGIS Desktop and Delphi+MapObjects development mode, we implement the prototype system with spatial data format conversion, storage, the spatial database connection and management, the operation of map. We realize the unified and effective storage management of multi-source spatial data. |
