人教社九年制义务教育中学《地理》课本封底、封面选用了4张卫星照片,北纬26°附近尼罗河—段河谷及周围地面的卫星照片,我国渤海湾附近地区的卫星照片。封底是地球卫星照片和卫星云图照片。这些照片都是人造地球卫星在宇宙中拍摄到的照片,所以叫卫星照片。下面我们主要介绍一下地球资源卫星。 地球资源卫星也叫陆地卫星,是以研究地球资源和环境动态监测为目的,专门探测、普查地球资源的航天卫星。航天卫星拍摄时高度较大,因此卫星照片的覆盖范围较大。一张卫星照片可以覆盖地面34 225km~2,这样把我国领土勘测一遍只需拍500张卫星照片,而利用飞机进行航空测量则要拍500万张航空照片。因此利用卫星照片可以进行宏观研究。
Humanities and Social Services Nine-year compulsory education secondary school “geography” textbook back cover, the cover selected 4 satellite photos, Nile near 26 ° latitude - section of the valley and the surrounding ground satellite photos, China’s Bohai Bay satellite image. Back cover is a satellite image of the Earth and satellite photos. These pictures are taken by artificial Earth satellites in the universe photos, so called satellite photos. Here we mainly introduce the earth resources satellite. Earth resources satellites are also terrestrial satellites. They are space satellites that specialize in detecting and censoring earth resources for the purpose of studying the dynamic monitoring of earth resources and environment. Astronauts were more highly photographed, so satellite photos covered a larger area. A satellite photo can cover 34 225 km ~ 2 on the ground, so that it is only necessary to take 500 satellite photos of China’s territory survey once again, and to make 5 million aerial photos using aircraft for aerial surveying. Therefore, the use of satellite photos can be macroscopic research.
