Defines an absolute orientation of a "positive axis" at each node of a grid.
instance_s (PK, M: CHAR VARYING(19))
Surrogate key of the table.
instance_create_date (O: TIMESTAMP)
e_and_p_data.instance_create_date
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.
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).
pty_absolute_orientation_array.azimuth
The azimuth of the "positive axis" clockwise from "north". This value asserts that all nodes of the grid have the same orientation. azimuth_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure.
data_value_sl (O: CHAR VARYING(16))
pty_absolute_orientation_array.data_value
The orientation of the "positive axis" defined at each node on a grid. These orientations may have been derived from the "chassis" orientation. Described using one or both of the following values: "azimuth" and "inclination".
description (O: CHAR VARYING(2000))
e_and_p_data.description
A remark or comment about the instance.
pty_absolute_orientation_array.inclination
The inclination of the "positive axis" relative to the downward vertical direction. This value asserts that all nodes of the grid have the same inclination. inclination_u: Defines the unit of measure. Defines a foreign key to table r_unit_of_measure.
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.
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".
activity_s (FSK, O: CHAR VARYING(19))
process_data.activity
Defines the activity which created this instance.
Defines a foreign key to table activity.
receiver_definition_s (FSK, O: CHAR VARYING(19))
pty_absolute_orientation_array.receiver_definition
May be a property of seismic geometry set. The grid must be the same as was defined by attribute receiver uid in the associated seismic geometry set (i.e., fixed facilities). If receiver uid is not defined in seismic geometry set then the grid must be the same as was defined by attribute field trace uid (i.e., moving facilities). For receivers, the "positive axis" is the direction along the axis of the receiver such that the case motion in that direction produces a positive initial voltage and a positive number on tape.
Defines a foreign key to table geophysical_geometry_set.
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.
source_definition_s (FSK, O: CHAR VARYING(19))
pty_absolute_orientation_array.source_definition
May be a property of seismic geometry set. The grid must be the same as was defined by attribute source event uid in the associated seismic geometry set. For sources, the "positive axis" is the direction of initial ground motion.
Defines a foreign key to table geophysical_geometry_set.
