青藏高原湖泊测深数据(2000,2018)
收藏资源简介:
数据由三个字段组成:经度、纬度和湖泊深度。利用声呐设备在湖泊上走航测量得到的水深数据,GPS同步测量得到的经度和纬度。利用湖水盐度和温度数据校正声呐测得的深度数据,并剔除数据异常点。利用水深数据可以插值形成湖泊水下地形图。利用水下地形图可以计算湖泊的储水量,评估青藏高原湖泊总水量。利用水下地形图结合遥感数据还可以研究青藏高原湖泊水量变化特征及其影响因素,是亚洲水塔水量变化研究的重要组成部分。
This dataset contains three fields: longitude, latitude, and lake depth. Water depth data was collected via underway sonar surveys on the lake, while longitude and latitude data were synchronously measured using GPS. The sonar-measured depth data were corrected with lake water salinity and temperature data, and data outliers were removed. Underwater topographic maps of the lake can be generated through interpolation based on the water depth data. These maps can be used to calculate lake water storage capacity and assess the total water volume of lakes on the Tibetan Plateau. Additionally, combining the underwater topographic maps with remote sensing data enables research on the characteristics and influencing factors of water volume changes in Tibetan Plateau lakes, which constitutes a critical component of studies on water volume variations in the Asian Water Tower.
