地形数据的尺度效应对航迹规划的影响研究

对航迹规划地形建模中理想分析尺度的选择问题进行了研究。将DEM地形参数的计算值与真实值相比较,分析各种条件下尺度效应对飞行器航迹规划中地形参数分析的影响,结果表明航迹规划中应充分考虑地形因素,进行相关性分析后选择适应的尺度。

Research of the Terrain Data Scale Effect on Route Planning

This paper does some work on ideal scale choosing in the terrain data application of route planning. Considering the terrain data request of route planning, the paper analyses the effects of terrain data scale on the analysis of terrian parameter by comparing the calculation of DEM terrain data pretreatment with the reality. The result shows that terrain scale factor should be taken into consideration in the the route planning by analyzing the relativity to select the ideal scale.
