利用航磁航放测量绘制地形等高线图的方法与应用

低空航磁航放测量系统,是以三角翼飞行器为载体的一套完整的航测系统,在找矿与地质填图中已经得到示范与应用。为了了解测区内地物变化、地表升降以及矿区尾矿处理等地形变化情况,利用本系统在空中采取数据的全面和精确性,提取空中定向、定位与离地高度数据并进行计算,从而获取同测区等高线地形图件。文章通过对多宝山示范项目实例,介绍利用低空航磁航放测量系统获取地形图的方法与应用。

Application of aerial magnetic method and airborne radioactive measurement in plotting contour map

The low altitude aeromagnetic airborne radioactive measurement system, a complete set of aerial system carrier to delta wing aircraft, has demonstrated application in prospecting and geological mapping. In order to understand the change of the surface of geo-object, lifting and the surface mine tailings treatment and other terrain, the system was conducted in the air to capture a comprehensive accurate data. Then air orientation, location and altitude data were extracted and calculated, finally contour map was plotted. A case study in the Duobaoshan mine area was illustrated in this paper for demonstrating the application of the system.
