【摘要】 主要依据我国现行的铁、锰、铬矿地质勘查规范(DZ/T0200-2002)的要求,结合工作实际,在MAPGIS6.7环境下,使用平移、旋转准确绘制外推资源储量边界的二种方法,并阐述了具体的绘制步骤,结果证明,用这些方法绘制的图件不仅相对精确,还便于修改。更多还原

【Abstract】 Based on China’s current iron,manganese,chrome minral exploration specifications(DZ/T0200-2002) requirements and combined with the actual work,this paper introduces two kinds of methods,to create extrapolative reserves’ boundary preciously-using moving and rotating describes the steps in detail in the Mapgis 6.7.The results show that using these methods in drawing maps would be relatively accurate,but also convenient to modify.更多还原
