遥感影像判读时,一般把影像形状、大小、色调、本影、落影、组合图案作为判读主要依据。下图是北美西部海岸区域,某季节一次天气系统过程中的遥感图像,读图回答下列问题。

小题1: 在像片判读中,有助于获得地物的立体感判读的主要依据;

A.影像形状

B.本影

C.落影

D.组合图案小题2:半年后,如再次拍摄该地区,则获得的图像对比,色调差异最大的区域是

A.甲

B.乙

C.丙

D.丁

答案

小题1:B 

小题2:A

题目分析:

小题1:色调是指物体反射的光线中以哪种波长占优势来决定的,不同波长产生不同颜色的感觉,色调是颜色的重要的特征,它决定了颜色本质的根本特征。不透明体遮住光源时,如果光源是比较大的发光体,所产生的影子就有两部分,完全暗的部分叫本影,半明半暗的部分叫半影。落影,是一个物体在另一个物体上产生的影子,比如一个雨篷在墙面上产生的影子,或者一个构件在另一个弧面上产生的影子。总结就是,这个影子是物体A在承影面B上产生的影子。这个影子叫落影。从像片中可以看出该像片主要是由影像形状和本影组成,有助于获得地物的立体感的主要是本影,B对。影像形状主要判读地物形状,A错;像片中看不出落影,C错;获得地物的立体感不用组合图案,D错。

小题2:像片为一次天气系统过程中的遥感图像,从像片中可以看出甲地主要是云层覆盖地区,半年以后出现相同天气系统的可能性不大,A对;乙为海面上稍有云层,但不如甲地厚,半年后不如甲地变化明显,B错,丙丁地区晴天,图像为当地地面状况,半年后有所变化,变化没有甲大,CD错。
