遥感技术在机场净空分析中的应用

Application of Remote Sensing Technology in Airport Clearance

遥感技术是一种高效而精确的地形测量技术,它由于其自身非接触的测量方式,在广阔复杂地形勘测中得到广泛运用。常规机场净空测量方式是在二维高程的基础上进行,精度低且操作复杂。本文首先介绍了机场净空的要求以及常规测量方法,然后结合遥感技术和机场区域三维模型图,建立三维机场净空分析模型,该模型可以准确模拟机场周边地形以及净空限制范围。最后结合实例和三维净空模型给出了具体分析结果及周边物体超高数值。该技术不仅能提高机场净空分析准确率,同时提高了操作效率,为类似机场净空分析提供了参考。

Remote sensing technology is an efficient and accurate topographic survey technology.Because of its own non-contact measurement method,it is widely used in broad and complex topographic survey.The conventional airport clearance measurement method is based on the two-dimensional elevation,which has low accuracy and complex operation.This paper first introduces the requirements of airport clearance and conventional measurement methods,and then establishes a three-dimensional airport clearance analysis model combined with remote sensing technology and airport area three-dimensional model map.The modified model can accurately simulate the terrain around the airport and the clearance limit range.Finally,combined with an example and three-dimensional clearance model,the specific analysis results and superelevation values of surrounding objects are given.This technology can not only improve the accuracy of airport clearance analysis,but also improve the operation efficiency,which provides a reference for similar airport clearance analysis.
