| 摘 要： | 南极查尔斯王子山脉实地科学考察的顺利开展需要该区域1:50 000基础地理信息数据作为支撑。国产高分辨率资源三号立体影像为基础地理信息数据的获取提供了必要的遥感数据支持。充分利用资源三号立体数据，在冰、云和陆地高程卫星（the ice, cloud, and land elevation satellite, ICESat）上的地学激光测高系统（Geoscience Laser Altimeter System, GLAS）等多源遥感信息的辅助下，制作了南极查尔斯王子山脉1:50 000基础地理信息成果，并对其进行了精度分析。分析结果表明，数字高程模型（DEM）的高程精度优于5.31 m，数字正射影像图（DOM）成果与南极洲陆地卫星影像镶嵌图比较的较差中误差为16.30 m。因此，在南极地区利用资源三号立体数据集成各种遥感数据制作1:50 000基础地理信息成果是高效实用的。

| Abstract: | To ensure the implementation of on-site scientific investigation in Prince Charles Mountains of Antarctica, the 1:50 000 Fundamental Geographic Information is an urgent need. Domestic ZY-3 high resolution stereographic satellite imagery provides remote sensing data support for producing fundamental geographic information. Combining this imagery with ICESat GLAS laser altimetry data and other multi-source remote sensing information, we produced 1:50 000 fundamental geographic information for the Prince Charles Mountains in Antarctica using ZY-3 Stereographic Data, and analyzed the accuracy. Our results show that the vertical precision of Digital Elevation Model was better than 5.31m, and the RMSE for the differences between Digital Orthophoto Map and Landsat Image Mosaic of Antarctica was 16.30m. Therefore, our acquisition method can be considered as an effective and practical method for producing 1:50 000 fundamental geographic information based on ZY-3 Stereographic Data integrating imagery with multi-source remote sensing information from Antarctica. |
