Columbus Large Image Format (CLIF) as used in the October 28, 2007 collection

• The image frames were taken simultaneously from a matrix of cameras.
• The fields of view from neighboring cameras overlap and can be mosaicked to form a combined image of the scene.
• The relative positioning of the cameras as shown from the camera viewpoint onboard the aircraft is as follows:

 _____ _____ _____
|     |     |     |
|  3  |  1  |  5  |
|_____|_____|_____|
|     |     |     |
|  2  |  0  |  4  |
|_____|_____|_____|

• The images from the cameras along the top row of the matrix need to be rotated clock-wise 90 degrees and flipped horizontally to be put in the correct orientation with respect to the plane.
• The images from the cameras along the bottom row of the matrix need to be rotated coun-terclockwise 90 degrees and flipped horizontally.
• The images are numbered with the camera (from 000000 to 000005) followed by a dash, followed by the frame number (e.g. 100000) with a .raw extension
• Each image is 4016 by 2672 pixels, in 8-bit grayscale raw format.
• Each image is approximately 10 MB.
