Summarizes the acquisition geometry associated with the geometry set.
instance_s (PK, M: CHAR VARYING(19))
Surrogate key of the table.
instance_create_date (O: TIMESTAMP)
e_and_p_data.instance_create_date

last_updated (O: TIMESTAMP)
e_and_p_data.last_updated
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).
description (O: CHAR VARYING(2000))
e_and_p_data.description
A remark or comment about the instance.
instance_creator (O: CHAR VARYING(80))
e_and_p_data.instance_creator
This is the person, company or application that created this instance. This identifies the party responsible for loading this instance.
last_updated_by (O: CHAR VARYING(80))
e_and_p_data.last_updated_by
This records the person or application making the update to this instance.
preferred_flag (O: CHAR(1))
property.preferred_flag
The flag is set to True if this instance of property is the preferred value in this data store of this type of property for the object which this property describes.
pty_seismic_geometry_summary.receiver_line_nominal_spacing
The nominal distance between receiver lines. receiver_line_nom_spacing_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure.
receiver_point_count (O: INTEGER)
pty_seismic_geometry_summary.receiver_point_count
The maximum number of receiver points on any single receiver line.
pty_seismic_geometry_summary.receiver_point_nominal_spacing
The nominal distance between receiver points on a line. receiver_point_nom_spacing_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure.
source (O: CHAR VARYING(80))
e_and_p_data.source
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".
pty_seismic_geometry_summary.source_line_nominal_spacing
The nominal distance between source lines. source_line_nominal_spacing_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure.
pty_seismic_geometry_summary.source_point_nominal_spacing
The nominal distance between source points on a line. source_point_nominal_spacing_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure.
station_line_count (O: INTEGER)
pty_seismic_geometry_summary.station_line_count
The number of station lines independent of the type of facility utilized at the stations.
station_point_count (O: INTEGER)
pty_seismic_geometry_summary.station_point_count
The maximum number of stations on any single line independent of the facilities utilized at the stations.
station_point_total (O: INTEGER)
pty_seismic_geometry_summary.station_point_total
The cumulative number of stations on all lines independent of the type of facility utilized at the stations.
process_data.activity
Defines the activity which created this instance.
Defines a foreign key to table activity.
r_spread (FNK, O: CHAR VARYING(80))
pty_seismic_geometry_summary.ref_spread
A descriptive type of the spread, such as end on, split dip, broadside T, broadside L, etc.
Defines a foreign key to table r_spread.
property.represent
This is the property that is the original for which this representation is an equivalent representation. represent_s: Implements a foreign key to a row in one of the tables projected from entity property depending on the value of the next column (See below). represent_t: Defines the name of the referenced table. Possible values are defined in @property.
