摘要
以河北省铁尾矿为例,通过GIS技术建立矿山空间数据库,根据专题现象确定地图主题内容和最佳表示方法,设计图形符号和注记的形状、尺寸、颜色,直观表达了矿产的位置、矿量等基本属性信息,并通过多要素地图反映了各种现象的相互关系,为矿山资源的保护提供辅助决策。
A mine spatial database is set up by GIS.Taking the iron-tailings in Hebei province as an example,the map＇s theme content and the best representation method are determined based on the thematic phenomenon.The shape,size and color for graphic symbols and notes are designed to intuitively express information on the position and quantity of ore reserves and other essential attributes.It also reflects the relationship among various phenomena through multi-element maps,providing assistance for decision making in mine resources protection.
