基于资源三号卫星影像对东南极格罗夫山地区DEM的建立及其精度分析
Generation and accuracy of a digital elevation model for Grove Mountains,East Antarctica based on ZY-3 satellite images
摘要
Abstract
The Grove Mountains region in East Antarctica is one of the core areas for Chinese National Antarctic Research Expeditions.A high-precision Digital Elevation Model(DEM)for the region is important for sup-porting Antarctic expedition and glacier research.The ZY-3 satellite is a high-resolution optical stereo map-ping satellite.Its images fully covers the core area of the Grove Mountains.This paper uses the triple line-ar-array stereo images to generate a high-resolution DEM for the Grove Mountains region(ZYDEM).Taking the elevation control points in the region as the reference,the elevation accuracy of ZYDEM is(-2.57±8.15)m.Taking filtered ICESat-2 footprint data in the region as the reference,the elevation accuracy of ZYDEM is(0.47±2.03)m.The accuracy of ZYDEM is higher than that of common Antarctic DEMs,including Bam-berDEM,ICESatDEM,and TanDEM-XDEM,and is close to that of the Reference Elevation Model of Ant-arctica(REMA).The establishment and accuracy analysis of ZYDEM demonstrates the feasibility of using the ZY-3 satellite for the Antarctic region.关键词
