Defines the horizontal 2D location of each node in a 1D grid. Note that a plot of the locations may or may not form a coherent line.
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).
data_value_sl (O: CHAR VARYING(16))
pty_location_array.data_value
The horizontal location of the seismic facility at the time of each source event.
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.
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.
pty_location_array.potential_field_meas_def
Data value defines the location of each measurement. The grid must be the same as was used by attribute measurement uid in potential field geometry set.
Defines a foreign key to table geophysical_geometry_set.
pty_location_array.potential_field_stn_definition
Data value defines the location of each station. The grid must be the same as was used by attribute station uid in potential field geometry set.
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.
pty_location_array.seismic_facility_track
May be a property of seismic facility track. Data value defines the location of the referencing facility at the time of each source event. The grid must be the same as was defined by attribute source event uid in the seismic geometry set associated with seismic facility track.
Defines a foreign key to table seismic_facility_track.
source_definition_s (FSK, O: CHAR VARYING(19))
pty_location_array.source_definition
May be a property of seismic geometry set. Data value defines the location of each source event. The grid must be the same as was used by attribute source event uid in seismic geometry set.
Defines a foreign key to table geophysical_geometry_set.
station_definition_s (FSK, O: CHAR VARYING(19))
pty_location_array.station_definition
May be a property of seismic geometry set. Data value defines the location of each station. The grid must be the same as was used by attribute seismic station uid in seismic geometry set.
Defines a foreign key to table geophysical_geometry_set.
