... iterative linearized updates (Guillaume et al., 2001). In linear gridded tomography (Woodward et al., 1998), velocity model parameters consist of regular 3D grids describing continuous spatial variations of velocity and/or anisotropy. The gridded approach cannot easily handle strong velocity contrasts...
