3DPSDM

3DPSDM: 3DGeo's 3-D Kirchhoff prestack depth migration (3DPSDM) package is based on a state-of-the-art implementation of the algorithm designed to achieve maximum efficiency on parallel-vector and cache-based supercomputers. The algorithm includes several choices of anti-aliasing and an amplitude equalization operator to preserve the amplitude information in the final image even when the spatial sampling of the imput data is irregular. Through scaling of the input and output data, 3DPSDM can be run on workstations as well as supercomputers, though the best efficiency is obtained on larger computing platforms.
