An inversion method to determine a3D laterally inhomogeneous layered velocity model by means of kinematic wavefield attributes is introduced. The presented method belongs to the class of layer stripping algorithms. It determines the layer velocities that are assumed to be constant within a layer and constructs the boundaries of the layers (interfaces) starting with the uppermost interface. The input
