FEATURE RELIABILITY DATE (FEATURERELIABILITY) [Date; Yes; 0; 0; 36]

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.

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.

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

26 - Operational/Abandoned building & Abandoned homestead
0 - Ruin

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

When a Landmark Area and Ruin to Scale are adjacent then the ruin boundary symbology should take precedence. When a Landmark Area or Ruin to Scale is adjacent to an operational building then the symbology for Landmark Area or Ruin to Scale should take precedence.

At 1:100 000 buildings captured from the base material/digital data will be shown unless there is strong evidence they no longer exist. This capture is subject to data generalisation principles, appropriate for this scale.

At 1:250 000 all feature occurrences existing in the TOPO250K NTDB will be retained unless there is clear evidence they no longer exist.

New buildings will be captured from supplied imagery where there is strong evidence on the image to support the interpretation or where other revision source material assists the interpretation.

Buildings will not be shown within Built-up areas. Buildings will be shown in Recreation Area, Cemetery and Built-up area void features.

A group of buildings that cannot be shown individually may also be shown by a representative pattern of building features. A group of buildings will not be aggregated to form a building area.

A significant building such as a papermill that cannot be drawn to scale will be shown using symbol 40. Significant buildings should have landmark value. It is not intended that farm or poultry sheds would be considered significant, particularly in areas where there are many such features. Some examples of significant buildings may be: power stations, hospitals, oil refineries. In remote areas features may take on more significance than in populated centres for example: large roadhouses, paper mills, etc.

At 1:100 000 operational buildings of known function should have the item 'BUILDINGFUNCTION" populated. Buildings whose function is not known or not in the represented list should be coded as “other or function unknown”. Text_notes should reflect the function of the building.

The Building Function item is to be used only at 1:100 000 scale. At 1:250 000 the item will not be applicable. The Building Function 'Dwelling' is defined as a place of residence.

Each Building Area polygon will contain a single building point feature centred within its extents.

Named buildings other than operational homesteads will be cloned as Place Name. The name will be held against the Place Name feature type and not as a textnote for building.

Operational homesteads will be shown as a Homestead feature type and cloned as a building point subject to the rules for inclusion of homesteads. Operational homesteads that fail the rules for inclusion as Homestead feature type may still be shown as unnamed buildings. Abandoned homesteads will be named in a similar manner to the method of capture for Homestead feature type in reference to Appendix C. (i.e In densely settled areas Homesteads are not captured unless considered significant (e.g. historical), therefore buildings of classification 'Abandoned Homestead' should not be named in densely settled regions unless they are also considered significant).

Outstations will be considered as Homesteads.

Outcamps will be considered as Place Names. If buildings are present they should be shown as building areas with no text_note. The Place Name should be coincident with a designated building.

Substations will only be included as buildings when there is clear evidence of it meeting the definition of a building. Substations shall not be named unless instructions are provided to do so by GEOSCIENCE AUSTRALIA.

If black type falls unavoidably over the building symbol, the feature’s symbol attribute will be ‘0’ (non-printing).

Buildings other than homesteads will be named or labelled where they have a distinctive function, eg. ‘factory’, ‘sawmill’, ‘Wikipin Agricultural College’, or where they were labelled on the latest previous edition map.

Operational homesteads will be shown by the feature type ‘Homestead’ subject to the rules for inclusion of homesteads. Abandoned homesteads and operational homesteads that fail the rules for inclusion as Homesteads feature type may still be shown as buildings.

Abandoned homesteads will be labelled ‘abandoned’.  

If black type falls unavoidably over the building symbol, the feature’s symbol attribute will be ‘0’ (non-printing).

Buildings other than homesteads will be named or labelled where they have a distinctive function, eg. ‘factory’, ‘sawmill’, ‘Wikipin Agricultural College’, or where they were labelled on the latest previous edition map.

Operational homesteads will be shown by the feature class Locality code ‘Homestead’ subject to the rules for inclusion of homesteads. Abandoned homesteads and operational homesteads that fail the rules for inclusion as Locality homesteads may still be shown as buildings.

Abandoned homesteads will be labelled ‘abandoned’.
