【摘要】 充分利用南极地区的多种数据源(资源三号,ICESat/GLAS、LIMA DOM、ASTER GDEM),对其进行了相对精度分析,确定了利用多种数据源进行南极3D产品生产的技术路线,解决了目前我国极地中小比例尺3D产品基础地理信息数据生产关键技术的空白,提高了我国南极3D产品生产能力。更多还原

【Abstract】 This paper use Multi- source data( ZY- 3,ICESat / GLAS,LIMA DOM,ASTER GDEM) of Antarctic area,analysis accuracy of these data,determine the technical route of the Antarctic 3D production using a variety of data sources. That solves the key technology of production of China’s polar medium and small scale 3D product basic geographic information and data gaps,improve the production capacity of China’s Antarctic 3D products.更多还原
