摘要: ZiYuan-3 (ZY-3, meaning Resource-3) is China's first civilian multispectral satellite with high-resolution stereo mapping capability. The along-track images of ZY-3 allow the generation digital elevation models (DEMs) for various applications. This article evaluated precision derived DEM and orthoimages data a test site in Northeastern China. Pixel offset GPS survey were used to evaluate image products. Orthoimages by incorporating rational polynomial coefficients (RPCs) orbits reference DEMs, including Advanced Spaceborne Thermal Emission Reflection Radiomete (ASTER) global model (GDEM) model. generations categorised into four approaches depending on RPCs, control points and/or DEMs used. When only ASTER GDEM was used, forward backward viewing sensors showed clear pixel offsets ag...
