Stochastic Signal Processing > Spatial Data Quality Assessment

Spatial Quality Assessment or S Q A quantifies the reliability of geophysical data sets at the time of processing supervision and or before engaging in further geophysical workflows. Usual Q C's applied to geophysical data sets are about standard statistics computations. S Q A offers a more robust alternative that assesses the spatial consistency of geophysical data sets by computing Spatial Quality Indexes or local spatial noise to signal ratios.

An example is given on the S Q A of a pre stack amplitude gather
