The description of accuracy of a coordinate set that provides a location.
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).
confidence_level (O: FLOAT(6))
pty_location_accuracy.confidence_level
This defines the degree of confidence used to express these uncertainty values. For example, 95 represents a 95% certainty that the actual position is within the range described.
description (O: CHAR VARYING(2000))
e_and_p_data.description
A remark or comment about the instance.
pty_location_accuracy.error_length
A measure of length that may be used to quantify the accuracy of a location coordinate set. This length describes the maximum error that may reasonably be expected for the location. error_length_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".
uncertainty_ellipsoid_sl (O: CHAR VARYING(16))
pty_location_accuracy.uncertainty_ellipsoid
The set of parameters to describe an ellipsoid, ellipsoid origin offset and ellipsoid orientation at the point being qualified.
activity_s (FSK, O: CHAR VARYING(19))
process_data.activity
Defines the activity which created this instance.
Defines a foreign key to table activity.
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.
