| 内容記述 | Whole Shikoku island, JAPAN was selected as test area. In Shikoku, many slope failures are occurred by the torrential rain every year. The slope failures induce other serious disaster such as landslide, mudflow and debris flow. Therefore, slope failures must be found immediately. In the case of remote area, finding slope failures is very difficult. | |||||||||

| 内容記述 | PRISM sensor mounted on ALOS has three lines scanner with 2.5m ground sampling distance. Then, three dimensional (3D) measurements can be carried out in 2.5m spatial resolution. The 3D measurement using PRISM has a potential to detect a big scale slope failure. | |||||||||

| 内容記述 | For accurate 3D measurement, Ground Control Points (GCP) must be prepared. Authors established GCP database for ALOS data in Shikoku. Now, over 500 points were surveyed by GPS VRS observation. There are about 20 GCP in PRISM coverage. The GCP database is opened to the public through web site of Kochi University of Technology. | |||||||||

| 内容記述 | There are several geometric transformation models for 3D measurement such as RPC, 3D projection and line scanner DLT. Those geometric transformation models were evaluated using GCP database. The result showed the accurate model was 3D projection. By using 3D projection, Ortho-Mosaic imagery of 36 PRISM scenes and 9 AVNIR2 scenes was generated in whole Shikoku island. Accuracy of the Ortho-Mosaic imagery showed less than 1 pixel. Then, established GCP database has enough accuracy for registration of ALOS data. | |||||||||

| 内容記述 | 3D measurement using PRISM was carried out using stereo matching. Image correlation method and least squares matching were combined for accurate stereo matching. The result of The 3D measurement showed 5m RMSE in 3D projection and line scanner DLT. In this study, 3D projection was also used for DSM generation. And 5 area were selected for evaluating generated DSM. The RMS error showed bigger in mountainous area rather than plane area. When GCP were prepared in high elevated area, the accuracy will be improve. | |||||||||

| 内容記述 | For change detection, two scenes of PRISM were used, which were acquired on 2006 and 2009 in kochi area. Digital Surface Models (DSM) of point cloud model were generated. The point cloud model was converted to 10m grid model to compare both DSM. A difference of each DSM was calculated by simple subtraction. The subtractive imagery had a striping noises. The reason of the striping noise was micro pulsation of sensor. The striping noise was eliminated by DFT. However, it was difficult to detect change. Next, Neighbor Correlation Coefficient (NCC) was calculated for change detection. This method can neglect gentle change such as striping noise. The change detection by NCC showed noises of DSM in plane area were detected very much. For accurate change detection, noises should be eliminated. | |||||||||
