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).
