| Abstract: | In order to research on the triangulation accuracy on the island and reef areas, some typical islands are selected. The images are captured by ADS40 which is the representative digital pushbroom camera. Two different schemes are used in GPS/IMU data processing. One is using differential GPS method and the other is using GPS precise point positioning method. In each scheme, the triangulation accuracy of combined adjustment with and without control points are compared and analyzed and the experiment results are concluded. |
