Defines values at nodes in a grid. If no "grid use" attributes are defined then the values will semantically identify each node. For prestack "trace" data this would typically represent properties such as "source event uid", "receiver uid" (or "channel uid"), "bin point index" and/or "bin line index".
This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance. Inherited from e_and_p_data.
This is the person, company or application that created this instance. This identifies the party responsible for loading this instance. Inherited from e_and_p_data.
This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships). Inherited from e_and_p_data.
The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC". Inherited from e_and_p_data.
Defines the binsets which defined the "bin point index" and/or "bin line index" values used in seismic data header. If only one is defined then all values are assumed to apply to the definition in the same binset. If more than one is defined then a "binset uid" value must be defined in the header to qualify each index value/pair. Each "binset uid" value must match the value of attribute binset uid in one of the referenced binsets. Each seismic_header may use bin index definition in one or more header_bin_index_utilization.
Defines the binset variants which defined the "bin point index" and/or "bin line index" values used in seismic data header. If only one is defined then all values are assumed to apply to the definition in the same binset. If more than one is defined then a "binset uid" value must be defined in the header to qualify each index value/pair. Each "binset uid" value must match the value of attribute binset uid in one of the referenced binsets. Each seismic_header may use bin index definition in one or more header_bin_index_variant_util.
Defines the geometry sets which defined the "channel uid" values used in attribute seismic data header. If only one is defined then all values are assumed to apply to the definition in the same geometry set. If more than one is defined then a "channel geometry set uid" value must be defined in the header to qualify each "channel uid" value. Each "channel geometry set uid" value must match the value of attribute seismic geometry set uid in one of the referenced geometry sets. Each seismic_header may use channel uid definition from one or more seismic_header_channel_usage.
Indicates the data collections that include this instance of E and P data. Each seismic_header may be a member of one or more data_collection_content. Inherited from e_and_p_data.
These are the document specification parts that include this data value and define its meaning within a document specification. Each use may define a different meaning, and many uses are allowed. Each seismic_header may be included in one or more document_information_content. Inherited from e_and_p_data.
Specifies one or more graphical elements which are depicting this data item. Each seismic_header may be depicted by one or more graphical_element. Inherited from e_and_p_data.
Defines the geometry sets which defined the "receiver uid" values used in seismic data header. If only one is defined then all values are assumed to apply to the definition in the same geometry set. If more than one is defined then a "receiver geometry set uid" value must be defined in the header to qualify each "receiver uid" value. Each "receiver geometry set uid" value must match the value of attribute seismic geometry set uid in one of the referenced geometry sets. Each seismic_header may have receiver uid defined by one or more seismic_header_receiver_usage.
Defines the data sets which utilize this header information and which directly or indirectly use the same grid. Each seismic_header may utilized by one or more seismic_data_set.
Defines the geometry sets which defined the "source event uid" values used in seismic data header. If only one is defined then all values are assumed to apply to the definition in the same geometry set. If more than one is defined then a "source geometry set uid" value must be defined in the header to qualify each "source event uid" value. Each "source geometry set uid" value must match the value of attribute seismic geometry set uid in one of the referenced geometry sets. Each seismic_header may have source uid defined by one or more seismic_header_source_usage.
Defines the geometry sets which defined the "seismic station uid" values used in seismic data header. If only one is defined then all values are assumed to apply to the definition in the same geometry set. If more than one is defined then a "station geometry set uid" value must be defined in the header to qualify each "seismic station uid" value. Each "station geometry set uid" value must match the seismic geometry set uid value in one of the referenced geometry sets. Each seismic_header may have station uid defined by one or more seismic_header_station_usage.
Defines the geometry set that defines the semantics of the grid utilized by seismic data header. For example, if the grid specifies "source event uid" then it is implied that the source event uid grid of the referenced geometry set is being used. Each seismic_header may utilize grid from one seismic_geometry_set.
Defines the binset that specifies the semantics of the grid utilized by seismic data header. Each seismic_header may utilize grid from one geophysical_processing_grid.
