发布时间:2019-01-20 08:50
【摘要】:我国自主研发的立体测绘卫星资源三号已经成功发射并获取了大量影像,应用前景广阔。本文利用资源三号卫星遥感影像立体像对数据,进行甘肃省民勤县数字高程模型(DEM)生产试验,探讨了生产技术流程,检测了成果产品精度,着重对比航空摄影成图产品分析资源三号产品精度的可靠性,最后简要阐述了资源三号卫星遥感影像在基础测绘更新中的应用前景。
[Abstract]:Three dimensional surveying and mapping satellite resource has been successfully launched and acquired a large number of images in our country, which has a broad application prospect. In this paper, the (DEM) production test of the digital elevation model in Minqin County, Gansu Province, is carried out by using the stereo image of Resource-3 satellite remote sensing image. The production technology flow is discussed, and the precision of the product is tested. The reliability of the precision of Resource-3 product is compared with that of aerial photography mapping product. Finally, the prospect of application of Resource-3 satellite remote sensing image in the updating of basic surveying and mapping is briefly described.
