I have more than 200 photos to register and none of then are aligned with the cardinals. The registering process considers the image as North at the top so I have to rotate the images or rotate my camera. Rotate the images seem more appropriate since I know the headings but I would like to rotate then by software instead one by one. The solution would be to read the bmp image rotate it and write it back and then register them. I would like to get a hold on the bmp, tiff data structure. If you have any link or source of this information I would appreciate you help. Dyan C. Catamaran GIS/RS Depto. Coord. Phero Tech Inc.
