【摘要】 四川省矿区环境评价空间数据库采用面向对象的Geodatabase地理数据模型,通过ArcSDE空间数据引擎连接,把空间数据都存储在关系数据库Oracle9i中。结合矿区基础地理数据与矿山环境、地质灾害、基础类等专题数据,构建核心矿区空间地理信息框架和基于B/S和C/S的系统,实现有效地存储、管理和发布四川省各地矿区研究中所获得的大量的宝贵的资料。更多还原

【Abstract】 The Sichuan mining area geology environment appraisal system spatial database uses the object-orien-ted Geodatabase geography data model. Through the ArcSDE space data engine connection,all saves the spatial data in relational database Oracle 9i. Database unifies the mining area foundation geography data and the mine environment,the geological disaster,geology special data and so on the foundation class,constructs the core mining area space geography information frame and based on B/S and C/The S system,the realization effectively saves,manages and issued in the Sichuan each place mining area research obtains the massive precious materials,provide the policy-making support for the mining area sustainable development quality synthetic evaluation.更多还原
