FEATURE RELIABILITY DATE (FEATURERELIABILITY) [Date; Yes; 0; 0; 36]
The reliability date of the spatial object; Date to be adjusted only during spatial change or verification of an existing feature location or the capture of a new feature (see Section 1 Chapter 3.6);

Most Recent Reliability Date of Revision Source Material (or Base Material/digitial data for inital capture) used for Spatial Verification

FEATURE SOURCE (FEATURESOURCE) [String; Yes; 50]
This primary source used to determine the spatial location of a feature (For use in TOPO100K only;).

ATTRIBUTE RELIABILITY (ATTRIBUTERELIABILITY) [Date; Yes; 0; 0; 36]
The reliability date of the attribute object; Date to be adjusted only during attribute change or verification of an existing feature's item values or the capture of a new feature (see Section 1 Chapter 3.6);

Most Recent Reliability Date of Revision Source Material (or Base Material/digitial data for inital capture) used for Attribute Verification.

ATTRIBUTE SOURCE (ATTRIBUTESOURCE) [String; Yes; 50]
The primary source used to populate the attribute fields of a feature (For use in TOPO100K only;).

PLANIMETRIC ACCURACY (PLANIMETRICACCURACY) [Short Integer; No; 4] The standard deviation of the horizontal positional accuracy.The default value, when not specified in project instructions, will be as follows;
100 / 40

DATA SOURCE (SOURCE) [String; No; 50] This is the official name of the agency that originally captured the spatial object for the TOPO250K NTDB (For use in TOPO250K only) ; The default value when unknown or not specified in project instructions will be GEOSCIENCE AUSTRALIA.

UNIQUE FEATURE IDENTIFIER (UFI) [String; Yes; 10] Alphanumeric feature identifier defined for GEODATA SERIES 2 (For use in TOPO250K only;) (see Section 3 chapter 5.14)

FEATURE CREATION DATE (CREATIONDATE) [Date; Yes; 0; 0; 36] Date of creation of feature in the database. This field will be entered/edited automatically by GEOSCIENCE AUSTRALIA.

FEATURE RETIREMENT DATE (RETIREMENTDATE) [Date;Yes; 0; 0; 36] Date of retirement of feature in the database.This field will be entered/edited automatically by GEOSCIENCE AUSTRALIA.

PERSISTENT IDENTIFIER (PID) [Long Integer; Yes; 8] This field will be entered/edited automatically by GEOSCIENCE AUSTRALIA.

SYMBOL (SYMBOL) [Short Integer; No; 4] (Link to Symbol Dictionary)Symbol number/s applicable;

281 - Above ground/Elevated Pipelines whose product is not water
282 – Underground Pipelines whose product is not water
947 – Water Pipelines
0 - Pipeline running too close to another pipeline to be shown

TEXT NOTE (TEXTNOTE) [String; Yes; 50] Descriptive note to appear on map.

Geodatabase Rules

At 1:100 000 size and any other selection criteria apply to all feature occurrences. Submerged pipelines will not be shown.

At 1:250 000 size and any other selection criteria apply to new feature occurrences. All feature occurrences existing in the TOPO250K NTDB will be retained unless there is clear evidence they no longer exist. However, submerged pipelines will not be shown.

When a new undersized length of water pipeline exists between two canals which meet their selection criterion, then the section of water pipeline should be represented as a canal feature, accepting the attributes of its adjoining canals.

Only Pipelines included in the revision source material for pipelines will be added.
Two or more pipelines running closer that 1mm to scale, parallel to each other and carrying the same substance will be shown/captured as a single feature (ie. Physically combined to form one section of Pipeline) .Two or more pipelines running closer than 1mm to scale, parallel to each other and carrying the different substances will be symbolised as a single line. In this case one or more of the pipelines will have a symbol number 0 and the TextNote will describe both substances, for example ‘gas and oil pipelines’.In this situation, priority will be given to symbolising Gas/Oil pipelines over Water pipelines, which should then be symbolised to 0 (non-printing). Precedence should also be given to those pipelines having a RELATIONSHIP code of 1(Elevated) or 2 (Above Ground) over those with a RELATIONSHIP code of 3 (Underground).

Small pipelines serving individual homesteads or farmhouses will not be shown.

If base material/digital data and revision source material does not provide information on oil or gas pipeline relationships to ground level, then they should be attributed as Underground. However, if base material/digital data and revision source material does not provide information on water pipeline relationships to ground level, then this information be sought via an Action Request to Geoscience Australia.
 
Pipelines are to have an accompanying textnote eg ‘pipeline’, ‘gas pipeline’, unless the word ‘pipeline’ is included in the name. Underground pipelines will be labelled with a descriptive note, ‘underground’. Where applicable textnotes should be ordered so that detailed descriptive information such as 'underground' or 'disused' follows the more generic product pipeline information e.g. 'gas pipeline underground'

 

Inter-Feature Relationship Rules - Internal to Associated Dataset

Where one pipeline crosses another a node will be shown at the intersection point. ie. the arcs will be split.  

Inter-Feature Relationship Rules - External to Associated Dataset

Map Rules

Pipelines are to have an accompanying descriptive note eg ‘pipeline’, ‘gas pipeline’, unless the word ‘pipeline’ is included in the name. Underground pipelines will be labelled with a descriptive note, ‘underground’.

Pipelines will be masked where black type unavoidably overprints the feature. The break measurement will be 0.2 mm on either side of the type where it crosses the feature. (Note: the feature will be masked only on the map and will be complete in the data.)

Pipelines will be masked for Roads, Built Up Area and Recreation Areas(Feature Class) . The break will be the same as the width of the road it crosses.
