多比例尺矿图动态数据库的构建

Construction of dynamic data-base by multi-scall

改变了矿图绘制中传统的“绘图 -存图”模式 ,提出了“数据 -绘图”模式。设计了矿图动态绘制库的主要组成部分 ;原图数字化库 ,图形数据库和动态填图数据库的结构组成。给出了不同比例尺矿图的动态绘制过程。实现了利用一套数据进行多比例尺巷道的动态生成方法。

This paper presents the mode of data-drawing,and changes the mode of the traditional mode of mining-map drawing,drawing-store The main consisting parts of dynamic data-base are designed,including data-base of digital map from old,graph data-base and the dynamic filling-map data-base.The dynamic process of maps based on different scales is given and the method of drawing multi-scales roadways based on a set of data.
