This data set is aimed at Qi Yi glacier in Qilian Mountain. The data set includes serial number, longitude, latitude and elevation. The data set contains 51 records, mainly relying on the flower stalks arranged on the surface of the glacier as the measuring points. The m721 handheld GPS was used to measure the position and elevation of the measuring points at the flower pole. The measurement time of each measuring point was more than 30 minutes. The data set was measured in 2012 and 2017. Fully open sharing. Data set longitude, unit degree (°), latitude, unit degree (°), elevation, unit meter (m).
Self generated.
Based on the flower stalk as the measuring point position, jisibao m721 hand-held differential GPS was used to record the flower stalk position and altitude. In the data measurement, jisibao m721 hand-held differential GPS is calibrated, and the measurement time of each measuring point is more than 30 minutes; the 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
