摘要

航空照片及衛星影像真實地反映宏觀的岩土類別、地質構造、地貌、水系、植被、地質災害、土地利用、交通網等，詳加判釋可快速獲得大範圍地表的地工特性與限制條件，比傳統的地面調查還具效率與正確性。地表萬物都有反射及自行放射電磁波的特性，其反射曲線與輻射曲線各異，故利用遙測方法可以辨識各種物體與現象。本文並舉三個實例來說明其在地工方面的應用。

Remote sensing in the form of photographic, scanning and processing systems is one of the most appropriate means of recording existing ground conditions, of their potential for engineering projects and also of evaluating the effect, or potential effects, of the subsequent construction on the environment.It should however be stressed that remote sensing is only an aid to geotechnical investigations, providing information which is complementary to that obtained from field investigation. Indeed, if maximum benefit is to be gained from remote sensing techniques, it is essential that the interpretation of remote sensing images should be combined with ground checking.
