A location on the surface of the Earth expressed as a pair of north-south and east-west offsets from legal survey lines.

other_spatial_object (O, K, I: other_spatial_object(property))

Each pty_legal_survey_location may be a property of one other_spatial_object. Inherited from property.


well_surface_point (O, K: well_surface_point(pty_legal_survey_location))

Each pty_legal_survey_location may be a property of one well_surface_point.


facility_reference_point (O, K: facility_reference_point(pty_legal_survey_location))

Each pty_legal_survey_location may be a property of one facility_reference_point.


activity (O, K, I: activity(process_data))

Defines the activity which created this instance. Each pty_legal_survey_location may be the result of one activity. Inherited from process_data.


description (O, I: ndt_comment)

A remark, comment or description about the location value. Inherited from pty_location.


east_west_distance (O: ndt_accurate_length)

The distance of the offset in the east/west direction.


north_offset_first (O: ndt_boolean)

If true, the north/south offset is measured first. If false, the east/west offset is measured first.


north_south_distance (O: ndt_accurate_length)

The distance of the offset in the north/south direction.


preferred_flag (O, I: ndt_boolean) (1047)

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. Inherited from property.


data_collection (I, V: SET[0:?] data_collection(collection_content))

Indicates the data collections that include this instance of E and P data. Each pty_legal_survey_location may be a member of one or more data_collection. Inherited from e_and_p_data.


east_west_line (O: legal_survey_line)

This is the legal survey line used to describe the east/west offset for this location. This line is generally north-south in orientation. If this line is not specified, the east or west line of the designated legal survey area should be used. Each pty_legal_survey_location may use as line for east/west offset one legal_survey_line.


east_west_orientation (O: ref_offset_line_orientation)

The orientation of the east/west offset, either parallel to the north/south line or perpendicular to the east/west line. Each pty_legal_survey_location may east west orientation one ref_offset_line_orientation.


graphical_element (I, V: SET[0:?] graphical_element(depicted_object))

Specifies one or more graphical elements which are depicting this data item. Each pty_legal_survey_location may be depicted by one or more graphical_element. Inherited from e_and_p_data.


legal_survey_area (O: legal_survey_area)

This designates the legal survey area within which the legal survey location is specified. Each pty_legal_survey_location may be within one legal_survey_area.


north_south_line (O: legal_survey_line)

This is the legal survey line used to describe the north/south offset for this location. This line is generally east-west in orientation. If this line is not specified, the north or south line of the designated legal survey area should be used. Each pty_legal_survey_location may use as line for north/south offset one legal_survey_line.


north_south_orientation (O: ref_offset_line_orientation)

The orientation of the north/south offset, either parallel to the east/west line or perpendicular to the north/south line. Each pty_legal_survey_location may north south orientation one ref_offset_line_orientation.


process_data_item (I, V: SET[0:?] process_data_item(process_data))

Defines where this data was used by an activity. Each pty_legal_survey_location may be the value for one or more process_data_item. Inherited from process_data.


pty_location_accuracy (I, V: SET[0:?] pty_location_accuracy(pty_location))

Each pty_legal_survey_location may have a property of one or more pty_location_accuracy. Inherited from pty_location.


ref_east_or_west (O: ref_east_or_west)

The direction of the offset, either east or west.


ref_north_or_south (O: ref_north_or_south)

The direction of the offset, either north or south.

Local rules:

Uniqueness Constraint
other_spatial_object, well_surface_point, facility_reference_point, activity
Mandatory Relationship Set (1259)
Each PTY LEGAL SURVEY LOCATION must be instantiated with any combination of a LEGAL SURVEY AREA and both an EAST WEST LINE and a NORTH SOUTH LINE.
[I: property] Mandatory Relationship Set
Each PROPERTY must "be a property of" one object.
Supertype path(s):
process_data > property > pty_location > pty_legal_survey_location.
e_and_p_data > property > pty_location > pty_legal_survey_location.
