This data set is for MUZTAG area. The GPS control points joint survey data set includes the serial number, longitude (degree (°)), latitude (degree (°)) and elevation (meter (m)). The data set contains 389 records, which are mainly obtained by purchasing the national first-class control points in the region, using the national first-class control points for static measurement, synchronous measurement time of more than 1 hour, obtaining the glacier area control points by solving, and obtaining the dynamic joint measurement through DGPS RTK. The data set is only based on the glacier surface elevation in 2008, so it is not supplemented and improved, and is fully open and shared.

This data set is mainly measured data, and the main data sources are static measurement of national primary control points and dynamic joint measurement of DGPS RTK.
Through purchasing the national primary control points in the region, the global positioning system (GPS) of Huace T5 model is used for synchronous measurement for more than 1 hour, and the control points in the glacier area are obtained through the solution of hCG software; 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 reviewed.
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
