4.2. Image Data Figures 4-2 and 4-3 show the image data structure and a set of more detailed stereo image structure, respectively. Note: a line number of 5400 for Band 3B is valid from the geometric DB Ver. 2.0. Older version data has 4600 lines for Band 3B. The designed pixel sizes (Ground Sampling Distance) are 15 m, 30, and 90 m for VNIR, SWIR, and TIR, respectively.
