GPS拟合高程在大比例尺航外像控点测量中的应用

Application of the GPS fi tting elevation in large scale photo contral points of aerophtogrammetry in fi eld

本文应用GPS快速静态定位,用GPS高程拟合方法进行航外像控点区域网测量,结算出像控点的高程,并结合实例论证了其可行性。

The regional grid of the photo control points of aerophtogrammery in field was measured by using GPS elevation fitting method, including static positioning of GPS and calculation of elevation of phgto control points, meanwhile, expounded and proved its feasibility through a concrete example.
