摘要
阐述一种基于最小二乘平面拟合的单光子激光数据处理技术,采用重复轨道算法和最小二乘平面拟合算法,经过数据提取、数据处理等步骤,对ICESat-2-ATL06陆地冰数据进行处理,并以CookE2冰下湖为例,解算出某时间段的沿轨高程变化及其高程变化率.
Abstract
This paper describes a novel data processing technique for single-photon laser data based on least squares plane fitting,this method primarily employs the repetitive orbit algorithm and least squares plane fitting algorithm.Through steps such as data extraction and processing,the technique is applied to process ICESat-2-ATL06 land ice data.Using the CookE2 subglacial lake as a case study,accurate determination of the elevation changes and rates of elevation change along the track from October 2018 to April 2023 is achieved.
