By doing forward modeling we create data from a given set of model parameters. When the data form a different set of model parameters, I prefer to call the process forward mapping to emphasize that the transformation is done between spaces that cannot be measured directly. In this section I explain how to do the mapping from the elastic constants of a TI media to different sets of phase velocities.

- From elastic constants to phase velocities
- From elastic constants to phase velocities near the vertical axis
- From elastic constants to phase velocities near the horizontal axis
