| Abstract(in English) | This paper verified the analytical accuracy of long-term continuous land change using Consecutive DInSAR and PSI-SAR techniques. The Consecutive DInSAR is a method for obtaining high-precision continuous land displacement data by selecting image pairs of short time and small space baselines. The PSI-SAR has a disadvantage that all phase information cannot be utilized because it abandons the low coherence part. However, the Consecutive DInSAR can be utilized without abandoning the low coherence part, therefore, it is expected to perform a wide area, and high-precision land deformation estimation which could not be realized by the PSI-SAR. In this study, the effectiveness of the result was verified using GNSS data. As a result, the RMSEs of Consecutive DInSAR in Yokohama and Miura cities were 0.71 cm and 0.75 cm, respectively, and the RMSEs of PSI-SAR were 0.68 cm and 0.51 cm. Also, this paper can also clearly specify the spatial distribution of fluctuating regions. This research result is expected to contribute to disaster monitoring and environmental change observation in the future. |
