利用IRS-P5影像制作1∶50000 3D产品的试验研究

Experimental Study of Production for 1∶50 000 3D Products Using IRS-P5 Images

讨论了利用IRS-P5卫星遥感影像立体模型进行1∶50000 DEM,DOM,DLG等地理信息产品生产的相关问题,并进行了精度检测;同时与传统的航空摄影测量方法在原始资料获取、生产效率、工作量、数据成本等方面进行了对比分析。

This paper discusses the related problems of production for 1∶ 50 000 DEM,DOM and DLG using IRS-P5 images,and checks the accuracy of the products.Simultaneously,it compares with the traditional aerial photogrammetry techniques on the aspects of acquiring of source materials,production efficiency,workload and data costs,etc.
