摘要
以陕北某矿一盘区地形图为例,利用MapGIS软件和Surfer软件,通过提取地形图上高程控制点的图元,在MapGIS软件下将这些图元转换成地面高程控制点的X、Y坐标及地面高程Z数据,在Surfer软件下生成地面三维模型。该方法不用对地形等高线矢量化和赋高程属性,可快速生成地面三维模型,满足矿区实际生产需要。
Taking the topographic map of a panel of a mine in northern Shaanxi as example, the paper used Map-GIS and Surfer to extract pixels of topographic elevation control points , convert these pixels into coordinates X, Yand Z of surface elevation control points through MapGIS, generate three dimensional ground model throughSurfer.This method can generate rapidly three dimensional ground surface model without vectorization of topographiccontour lines and elevation attributes, meeting the actual demand in production of mines.
