This dataset encompasses the annual mean creep velocities of rock glaciers in Daxue Shan, located in the Southeastern Tibetan Plateau, between 2019 and 2020. These velocities have been meticulously estimated by integrating InSAR observations from both ascending and descending tracks with the Surface Parallel Flow (SPF) model. Initially, we utilized the Small Baseline Subset (SBAS) InSAR technique to map the movement of rock glaciers between January 2019 and December 2020. This was achieved by analyzing Sentinel-1A SAR imagery from both ascending and descending orbits. Following this, we merged the Line of Sight (LOS) measurements from the two tracks with the enhancements of the SPF model, which enabled us to calculate the three-dimensional creeping velocities of the rock glaciers with higher precision. In the final step, we projected the calculated 3D displacement vectors in a direction that is parallel to the slope of the terrain. This was accomplished through a process of vector addition, ensuring an accurate representation of the rock glaciers' movements.
