%X & emsp; This data set involves the monitoring data of slope surface displacement (inclinometer) of Liugou Reservoir in Xinjiang. It mainly includes WGS-84 coordinates of monitoring points at different times. The time range of the dataset is from August 21, 2019 to December 7, 2019. The time interval of this dataset is 1 time/second, and the average value is automatically calculated by day. The space scope covers the whole slope surface, and the plane scope is 30 × 20。& emsp; The integrated GNSS automatic monitoring station is a new technology for real-time monitoring of slope deformation. By fixing the satellite receiver on the monitoring point, each monitoring point continuously tracks and observes satellite signals for a long time, transmits the GNSS monitoring data to the monitoring center in real time through the data communication network (3G/4G/wired), and combines the observation data and starting coordinates of each reference station with the quasi real-time solution processing through the control center software, Finally, the three-dimensional coordinates of each monitoring point are obtained. The monitoring principle is shown in Figure 1. This technology can obtain millimeter level deformation monitoring precision equipment that has passed the national inspection. After years of field actual operation, the system operates stably and has high reliability, and is suitable for long-term unattended automatic operation in the field.& emsp; This project adopts the GNSS monitoring station of Wuhan International Navigation System, which adopts Thumb T200 receiver.
