航测成图与卫星影像测图的比较分析

近年来,高分辨率卫星影像在测绘生产中具有了较大的应用潜力,打破了过去测图单纯依赖航测的局面,并给航测成图带来很大的挑战。本文从航测成图与卫星影像测图的发展现状出发,对两者的成像原理、立体像对的获取方式、测图原理以及实际测图应用等方面进行了比较,说明了将两者结合起来应用的必要性。

Comparative analysis on the mapping with aerial image and satellite image

In recent years,the use of high resolution stereomapping satellites has broken the situation that mapping depends merely on aerophotogrammetry and has brought a big challenge to it.The development status of stereomapping with aerial image and satellite image is analyzed firstly.Then,it compares the principles of them and discusses their advantages and disadvantages in real application.Finally,it concludes that it is very important to combine them in application.
