An Improved Adaptive Template Size Pixel-Tracking Method for Monitoring Large-Gradient Mining Subsidence

Figure 7

Results of improved locally adaptive template size pixel-tracking method in SAR geometry. Black points represent GPS monitoring locations and there are 45 GPS monitoring locations in strike direction and 27 GPS monitoring locations in dip direction. The distance between two adjacent GPS points is about 20 meters. The black frame denotes an area with numerous ground cracks; even improved adaptive template size pixel-tracking method in this area cannot get accurate monitoring results.
