摘要
根据全国性煤炭矿产资源潜力数据库的建设要求,设计了系统的功能模型;并在充分考虑其他矿种的前提下,建立了基于Oracle Spatial和Geodatabase的煤炭空间数据模型,使用SDO-GEOMETRY类型字段保存GIS的空间数据,采用面向对象程序设计语言C#和ArcObjects组件的二次开发实现了该系统。应用结果表明,本系统不但达到了预期目标,并能为可供性分析等系统提供有效的数据支持。
Based on the construction requirements of nationwide coal mineral resouce potential, the authors design the functional model of goal system, and build the spatial data model of coal based on Oracle Spatial and Geodatabase with fully considered other minerals. The GIS spatial data has been saved by SDO-GEOMETRY field type, and the system is implemented by object-oriented programming language C# and the secondary development of ArcObjects. The application result shows that the system is not only meet the prospective goal, but also provides effective data support for affordances analysis system and other systems.
