摘要
以Worldview 30cm HD立体影像为例,探讨了亚米级高分辨率立体卫星影像在大比例尺地形图测绘生产中的应用,形成了一套基于高分辨率卫星影像的立体测图流程。以南京市某测区为例开展立体测图试验,通过对成图精度进行分析,结果表明,采用0.3 m空间分辨率Worldview立体卫星影像生成大比例尺地形图是可行的,能基本满足试验区1∶2000测图精度要求,但有一些地物无法准确判读与定位,需要外业实地补测。
Taking Worldview 30 cm HD stereo image as an example,this paper discusses the application of high resolution stereo satellite images with sub-meter accuracy in large scale topographic map production and explores a workflow of large scale stereo mapping based on high resolution satellite images.Then a stereo mapping experiment is carried out in a study area located in Nanjing and the mapping accuracy is analyzed.The experiment result shows that it is feasible to produce large scale topographic map using Worldview 30 cm HD stereo image and the mapping accuracy basically meets the requirements of 1∶2000 scale mapping.However,some objects can not be accurately interpreted and positioned from image,which requires field surveying and mapping.
