摘要
矿山数据模型研究,是"数字矿山"的核心组成部分,是矿山地理信息系统研究的热点和重点。笔者就矿山地理数据特点,从数据采集、数据表达等方面探讨了矿山地理信息系统(简称MGIS)所涉及的关键技术,在面向对象数据模型基础上建立了面向对象的矿山地理信息系统的数据模型,并以点、线实体阐述了矿山实体几何和属性对象数据模型的组成,为矿山地理信息系统的计算机实现建立了理论基础。
The research on data model of mines is an important part of ＂Digital Mine＂,and also is a researching hostpot of MGIS. Based on the characteristic of geographical data, this paper discusses the key technology related to the MGIS including data collection and data expression. Based on the object-oriented model, an object-oriented model of the mine geography information system was set up. This paper described the compositon of geometric and attributed object data model for the mine entity which provided a theoretical basis for MGIS computer practices.
