Finite diierence solution of the transport equation provides an eecient and accurate method for computation of 2D and 2.5D geometric acoustics amplitudes. These amplitudes can be used in simulation , migration and inversion formulas. Remodeled data based on high frequency asymptotic inversion using these amplitudes shows excellent agreement with both synthetic and eld input data.
