Broader Application of the Time-SIFT Method: Proof-of-Concept of 3-D-Monitoring Study Cases with Various Spatiotemporal Scales

This chapter aims to check the potential of the Time-SIFT method on varied test cases with different spatiotemporal scales, from the millimeter/minute to the kilometer/decade. It proposes five test cases to demonstrate the ability of the Time-SIFT method to provide coherent multi-temporal 3-D and/or 2-D datasets with limited or no external registration data. To demonstrate the ability of the Time-SIFT method to produce coherent multi-temporal dataset in various situations, the chapter presents distinct case studies: (i) spatiotemporal scales of the image datasets (ii) relative magnitude and spatial patterns of the expected changes; (iii) different data sources; and (iv) varied target phenomena. The authors expect that the Time-SIFT method will help to unlock the existing multi-temporal stereoscopic image archive for a broad range of change detection studies. Finally, to support access to the Time-SIFT method, the authors have opened it up as a module to the Agisoft Metashape software.
