利用航磁航放测量绘制地形等高线图的方法与应用
|
摘要
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。
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.
