Elevation Errors

Geoid Heights incorrectly applied.

Corrected Elevations are shown.

From a seismic imaging perspective these sort of bulk shift errors, in general, will be detected by the seismic processing contractors as part of their normal routine. However, their corrections may not be the best possible solution to the elevation errors as they are forced to make the best of what they are given with location data. This type of error also adds to the burden of pre-processing and quality assurance and are easily corrected with survey audit - improving processing flows and ensuring the integrity of the location data to start with.
