This data set is aimed at Glacier No.1 at the source of Urumqi River in Tianshan Mountains. The data set includes serial number, longitude, latitude and altitude. The data set contains 82 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. Fully open sharing. In the data set, longitude, unit degree (°), latitude, unit degree (°), elevation, that is, the glacier surface elevation in the current year, unit meter (m).
Self generated. This data set is measured data, and the main data sources are static measurement of national national primary control points and dynamic joint measurement of DGPS RTK.
In the data measurement, the static measurement of the national first level control points was carried out, and the step measurement time was more than 1 hour, and the control points in the glacier area were obtained through the calculation; the DGPS RTK measurement process was 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
