This data set is aimed at Lenglongling area, mainly ningtiaohe Glacier No.1. The sub ice terrain data set includes the serial number, longitude, latitude and thickness of control points. The data set contains 565 records. GPR ground penetrating radar (GPR) is mainly used to select a suitable cross-section on the glacier surface, and the glacier thickness data at this cross-section position is obtained by actual measurement. The data set is only for the glacier thickness in 2014, so it is not supplemented and improved, and the protocol is used for sharing. The data set contains four fields: serial number, longitude (unit: Degree (°)), latitude (unit: Degree (°)) and elevation (unit: meter (m), that is, glacier thickness of the current year). The data set is mainly the measured data in August 2014. The spatial datum is WGS84 / EGM96. Before using GPR, the propagation velocity of radar wave velocity in glacier ice is measured, and the relevant parameters of GPR are modified to ensure the most accurate thickness data of corresponding glacier.

This data set is mainly measured data, and the main data source is GPR ground penetrating radar.
In the data measurement, GPR ground penetrating radar is used to select the appropriate cross-section on the glacier surface, and then the glacier thickness is calculated in the software.
Before using ground penetrating radar (GPR), the propagation velocity of radar wave velocity in glacier ice is measured, and the parameters of GPR are modified to ensure the most accurate thickness data of corresponding glacier.
