2015年和2017年昆仑山煤矿冰川主流线冰面高程变化数据集

本数据集针对昆仑山煤矿冰川，数据集包括序号、经度、纬度、高程。数据集包含26条记录，主要依托冰川布设的花杆作为测点，使用M721手持GPS测定花杆位置和海拔高度，每个测点测量时间30分钟以上。采用完全开放共享。数据集中经度，单位度(°)，纬度，单位度(°)，高程，即当年冰川表面高程，单位米(m)。

This dataset focuses on the glaciers of the Kunlun Mountains Coal Mine. It includes four fields: serial number, longitude, latitude and elevation, and contains a total of 26 records. The survey points are mainly surveyor's poles laid out on the glaciers. The positions and elevations of these poles were measured using an M721 handheld GPS, with each measurement session lasting more than 30 minutes. The dataset is fully open and publicly shared. In this dataset, longitude is measured in degrees (°), latitude is measured in degrees (°), and elevation refers to the surface elevation of the glacier in the survey year, with the unit of meter (m).
