摘要
全国土壤侵蚀普查生产和收集了大量数据,需要建立数据库进行有效管理。数据库建设中,将全国土壤侵蚀普查各类数据按业务逻辑和时空关系管理,建立以地理空间为基础的"全国一张图"式的土壤侵蚀普查数据库。数据库采用面向服务的架构设计,用DTGIS空间信息服务平台提供的虚拟服务支撑各应用功能,利用栅格金字塔技术和DTSpatial对数据进行处理及入库管理,实现海量数据的无缝拼接和分层、分类存储管理,极大提高数据管理和使用的效率。
National census for soil erosion produces and collects lots of data. It needs to build database to go ahead effective management. In the progress of national database building, all the census data are managed with their logic and time-space relation. Based on geographic space,“one picture throughout the country”type of soil erosion census database is built. Using service-oriented architecture, the database supports various applications with DTGIS spatial information services platform, and processes data and manages data with pyramid grid technology and DTSpatial technology to realize massive data seamless and stratified classification storage management, which greatly improves the efficiency of data management and use.
