11. A method of estimating P-wave velocity in a near-surface region of a land area, comprising:
a first step of gathering control data for the near-surface region;
a second step of gathering vibrator dynamic data generated in the near-surface region in response to vibrator action on the
land area; and
a third step of estimating the P-wave velocity in response to both the control data and the vibrator dynamic data;
wherein the vibrator dynamic data includes at least one of ground stiffness data and ground viscosity data.
