DESCRIPTION:
Geometry setting is an updating trace identity, consists of shot coordinate, group (receiver) coordinate, source-receiver offset, and also setting common depth point (CDP). The objective of geometry setting is to obtain valid trace header values from acqusition geometry, especially the information belonging to the same subsurface depth (CDP) for improving S/N ratio.
Geometry setting requires acquisition parameters and navigation data. Either recorded navigation in an external file such as UKOOA P1/90 format (*.p190) or registered in the trace header is used to set geometry. Trace headers must already have the correct...
