在线卫星地图已经广泛应用于交通、导航等各种地图服务,既能反映地理要素实时变化,又能满足一定地理精度要求。以卫图作为底图,进行人工矢量化描绘和标注,可以快速制作总平面图。近年来,涉水项目申报进入空前的快节奏,应急突击项目时有发生,规划设计周期急剧压缩。基于卫星地图快速制作总平面图,较好地因应了勘测设计形势发展的要求,对于基层技术人员具有一定的实用价值。
Online satellite maps have been widely used in various map services such as transportation and navigation. They not only reflect the real-time changes of geographical elements but also meet certain geographical accuracy requirements. Weidong as a base map, the artificial vectorization of drawing and labeling, you can quickly make the master plan. In recent years, the declaration of wading projects has entered an unprecedented fast-paced, emergency assault projects have occurred from time to time, planning and design cycles drastically compressed. The rapid production of the general plan based on the satellite map has better applied to the development of the survey and design situation and has certain practical value for grass-roots technicians.
