在卫星图像上可以判读水系的形态特征。水系的形态与地质构造、岩性和地貌有密切的关系,例如,树枝状水系表现为支流与主流以锐角相交,主要分布在岩性均一、基岩较软的地区(如砂岩、页岩、黄土及海岸平原沉积岩发育的地区)。格状水系表现为支流与主流以直角相交,主要分布在垂直交叉的断裂、裂隙发育的沉积岩地区。

读图及材料,回答:

关于上述判读卫星遥感影像的过程,下列说法正确的是(   )

A:判读水系形态只能利用间接解译标志

B:根据水系形成推断地质构造和地貌是利用间接解译标志

C:在洪水期和枯水期拍摄的卫星影像其水系形态完全相同

D:河流和道路在卫星影像图上都是线状,无法应用直接解译标志加以判别

    Guided Walking Week April 2018

    Date: April 30th—May 7th 2018

    Location: Abdet, Costa Blanca

    A week of guided walking in the mountains around Abdet. Highlights include the climbing of Valencia's highest summit (Sierra de Aitana),traveling completely around the impressive Puig Campana, and several explorations in the Sierra de Aitana. Ancient trails lead through spectacular canyons (峡谷) to abandoned settlements situated high in the mountains. You will discover the snow trader routes which lead from the incredible snow holes high in the mountains down to the villages and towns on the coast. These years, golden eagles have made a return to this area, and you may also see other animals—wild goats, foxes, wild pigs and red squirrels.

    As part of the week you are invited to help clear some local walking paths. This involves clearing collapsed walls and rocks, cutting back fallen trees. This is of course optional and is just for half a day, and it's actually great fun!
