Cleared Line

FEATURE TYPE (FEATURETYPE) [String; No; 32] The code which identifies the type of topographic feature represented

Cleared Line

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;

99

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

At 1:250 000 Cleared Lines shown on the TOPO250K NTDB will be retained, where there is clear evidence they exist. New Cleared Lines may be added.

At 1:100000 Cleared Lines shown on the latest previous edition map and in the TOPO250K NTDB will be shown, where there is clear evidence they exist. New Cleared lines may be added.
 
Cleared lines will be TextNoted e.g ‘cleared line’. No reference to seismic lines should be made in the text_note field. If pre-existing features have been identified as seismic lines and are still visible on imagery, they will be redefined as 'cleared line' in the text_note field.

Cleared lines cannot overlap;
Sea, Lake, Reservoir, Watercourse Area or Canal Area.  

Cleared lines will be labelled, for example ‘cleared line’.

Cleared lines 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.)
