GEOPHYSICAL_GEOMETRY_SET (GEOPHYSICAL_GEOMETRY_SET)

(DDL)

Defines geometry associated with geophysical acquisition (e.g., seismic, gravity or magnetics). This may represent a composition of lines (survey, line composed of segments) or a line composed of points (line). There is no predefined intent on composition except for the identity of the components. For example, a survey can be composed of multiple lines if that is the most accurate description of the acquisition, or a line can be uniquely identified without association with a survey. A geometry set (e.g., a survey) can be may be composed of both seismic and potential field geometries.
