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.

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

At 1:100 000 size and any other selection criteria apply to all feature occurrences.

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.

Adjacent ponds will be shown as one polygon, separated by Settling pond internal lines. Settling pond internal lines less than 5 mm in length at map scale will not be shown within Aquaculture Areas.
 
Aquaculture Areas are to have an accompanying TextNote eg 'fish hatchery', ‘fish pen', 'aquaculture area’ unless the words 'fish hatchery', ‘fish pen' or 'aquaculture area’ are included in the name.  

Aquaculture Area will be bounded by entities in the WaterbodyBoundaries feature class.

Aquaculture Area cannot overlap;
Other polygon features in the Waterbodies Dataset.

Aquaculture Area cannot overlap;
Aviation (feature dataset), Sea, NativeVegetationAreas (feature class), CultivatedAreas (feature class).

Aquaculture Areas are to have an accompanying descriptive note eg 'fish hatchery', ‘fish pen', 'aquaculture area’ unless the words 'fish hatchery', ‘fish pen' or 'aquaculture area’ are included in the name.
