Abstract:

In order to investigate the proper design of the grid systems used in gridding or rectifying satellite pictures, an evaluation of errors from various sources has been made. It was found that the discrete grid intervals of both height and tilt are of vital importance in determining final accuracy. The rotation of the grid around the exposure subpoint is found to be permissible unless an accuracy of 0.1 degree is required. Where accuracy requirements permit, the authors OEC height grids may be replaced by ZE height grids which are less complicated and much easier to use. This change also permits the use of perspective height and tilt grids with less than 0.2 degree error. An evaluation of the gridding error due to the uncertainty of the spin-axis points revealed that it may be almost entirely eliminated by adopting a coupled rotation of the principal lines. Author
