人类的本性就是不断的探索周围环境,地图是对周围环境信息的长久记录。传统的地图依赖于人们的观测、整理。近年来,航天摄影和卫星成像技术为改善制图过程不断地提供有价值的信息,因而遥感卫星影像技术在制图中也变得越来越必不可少,对城市交通的影响也日益明显。卫星影像的最大好处是有规律的定期全球覆盖。而且卫星影像技术在各种制图的应用也越来越多。在过去的十年里,大量传感器的空间分辨率达到了分米级。
Human nature is to constantly explore the surrounding environment, the map is a long record of the surrounding environment information. Traditional maps rely on people’s observations, finishing. In recent years, aerospace photography and satellite imaging technologies continue to provide valuable information for improving the mapping process. As a result, remote sensing satellite imagery technology has become increasingly indispensable in cartography, and the impact on urban transport is also becoming increasingly evident. The biggest benefit of satellite imagery is regular regular global coverage. And satellite image technology in a variety of cartographic applications are also more and more. In the past decade, the spatial resolution of a large number of sensors reached the decimeter level.
