Since most engineering works are undertaken on planes (2-dimesnional x and y systems), it is essential to know how to transform coordinates from one system to another. For example, coordinates (positions) captured from a moving aircraft would normally be in pixel formats that need to be transformed into plane x and y systems that subsequently need to be transformed to more usable ground- based system. This chapter presents the techniques of obtaining transformation parameters (scales and translations). Methods presented range from simple affine transformation to least squares that are programmable.

Since most engineering works are undertaken on planes (2-dimesnional x and y systems), it is essential to know how to transform coordinates from one system to another. For example, coordinates (positions) captured from a moving aircraft would normally be in pixel formats that need to be transformed into plane x and y systems that subsequently need to be transformed to more usable ground- based system. This chapter presents the techniques of obtaining transformation parameters (scales and translations). Methods presented range from simple affine transformation to least squares that are programmable.
