【摘要】：拉斯曼丘陵地區(qū)位于東南極伊麗莎白公主地,中國南極中山站位于拉斯曼丘陵的東部,是中國南極科學考察的重要地區(qū)。數(shù)字高程模型(DEM)是南極冰蓋變化研究的基礎,衛(wèi)星測高數(shù)據(jù)是南極地區(qū)構建DEM的主要數(shù)據(jù)來源。CryoSat-2是新一代用于極地冰蓋和海冰監(jiān)測的測高衛(wèi)星,聯(lián)合2013年和2014年南極冬季的CryoSat-2測高數(shù)據(jù)以及中國、澳大利亞、印度三個國家現(xiàn)場測量的60余個地面高程數(shù)據(jù),利用克里金插值方法建立了拉斯曼丘陵地區(qū)200 m分辨率的DEM(簡稱LA-DEM)。利用未參與插值的地面高程數(shù)據(jù)對新建立的LA-DEM進行了驗證,并與Bamber 1km DEM、ICESat DEM、RAMPv2 DEM以及BEDMAP 2等四種國際上常用的南極DEM進行比較,結果表明LA-DEM的高程精度約為19.7 m,優(yōu)于其他4種南極DEM。
[Abstract]:The Rathman hilly area is located in the southeast pole Elizabeth princess, the Chinese Antarctic Zhongshan is located in the east of the Rathman hill. It is an important area for the scientific investigation of the Antarctic in China. The digital elevation model (DEM) is the basis of the study of the changes in the Antarctic ice cover. The satellite altimetry data is the main data source of the DEM in the Antarctic region,.CryoSat-2 is a new generation. The altimetry satellite used for polar ice cover and sea ice monitoring, combined with the CryoSat-2 height data of the Antarctic winter in 2013 and 2014, and more than 60 ground elevation data measured in three countries in China, Australia and India, using the Krikin interpolation method to establish the DEM (LA-DEM) of 200 m resolution in the lathman hilly region. Compared with four commonly used Antarctic DEM, such as Bamber 1km DEM, ICESat DEM, RAMPv2 DEM, BEDMAP 2 and other commonly used Antarctic DEM, the ground elevation data of the interpolated ground elevation is compared. The result shows that the LA-DEM elevation accuracy is about 19.7 m, which is superior to the other 4 kinds of Antarctica.
