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.
