Abstract

A study was conducted for developing an automatic sub-pixel matching methodology and applying on the imageries of one of the high-resolution SAR satellites, TerraSAR-X. The results indicated the accuracy of about 0.2 m in X direction, and better than 0.1 m in Y direction by comparing with the referenced GNSS observation data. This study was aimed to show the accuracy and feature of the displacement depending on the land cover types of the objects of the selected matching points using the three pairs of TerraSAR-X images of Tohoku region acquired pre- and post-earthquake in 2011. The developed methodology is focused on the spatial texture around the point, and there is some possibility that different kinds of objects except man-made buildings are utilized to calculate the displacement. Selected point of each sub-area was classified into several objects firstly, and the correlation coefficient and the amplitude for the selected points were analyzed subsequently. Finally the statistical analysis was conducted, and showed the errors of the displacement quantitatively for each object. This paper describes the knowledge for the applied methodology to highresolution SAR satellite imageries in detail, and also implies the key points for the improvement.
