This dataset is for the area around the main peak of West Kunlun, and the Global Positioning System (GPS) control point joint measurement dataset includes the serial number, longitude, latitude and elevation of the control points. The data set contains 8 records, mainly through the procurement of the national-level control points in the area, the use of national-level control points for static measurements, synchronous measurement time of more than 1 hour, through the decomposition of the glacier area control points; through the dynamic differential GPS for dynamic joint measurements to obtain. Data set longitude, unit degree (°), latitude, unit degree (°), elevation, i.e., glacier surface elevation in that year, unit meter (m)

This data set is mainly measured data, and the main data sources are static measurement of national primary control points and dynamic differential GPS dynamic joint survey.
Through purchasing the national primary control points in the region, the global position system (GPS) of Trimble 5800 model is used to synchronously measure the time of more than 1 hour, and the time is measured through the Trimble Geomatics office The software is used to calculate and obtain the control points in the glacier area; then the dynamic differential GPS is used to obtain the dynamic joint measurement, and the dynamic differential GPS measurement process is standardized and standardized, and strictly rechecked.
4-6 stations of China Survey X20 or T5 GNSS are used for joint survey, the synchronous measurement time is more than 1 hour, and 1-3 national control points are used for joint survey; the result calculation accuracy is controlled within 2cm
