TY - Data T1 - Digital elevation model dataset of the main peak area of Nyingchi Tanggula in 2014 A1 - Liu shiyin A1 - Wu Kunpeng DO - 10.12072/ncdc.DIMaC.db0053.2020 PY - 2020 DA - 2020-12-14 PB - National Cryosphere Desert Data Center AB - This data set is aimed at the main peak area of Nyainqentanglha mountain, including glacier and surrounding area in the main peak area of Nyainqentanglha mountain, and the digital elevation model of this area in 2014 obtained by using remote sensing images. The data set contains one band, and the complex data of the same ground object can be obtained by using the platform equipped with synthetic aperture radar sensor at the same time or two parallel observations. After accurate registration, complex interferograms can be obtained by conjugate multiplication of complex images. Based on the geometric relationship among flight platform, beam view and baseline, the digital elevation model of glacier area is obtained by unwrapping the phase information of complex interferogram. It is only aimed at the glacier surface elevation in 2014, so it is not necessary to supplement and improve it, and fully open sharing is adopted. The data set contains dem2014, a total of 1 band. Data set file name and band name are as follows: data set file name: 2014 Nianqing Tanggula Mountain main peak area digital elevation model data set, dem2014-2014 area digital elevation model, unit: meter (m).
