AUXILLARY CONTOUR Definition: – An additional contour used to aid relief interpretation over flatter or unique terrain,usually half the standard contour interval. The chosen values are of equal elevation above the Australian Height Datum. Alternate Terms: Supplementary Contour | Capture as a 3D polyline along the feature Capture at an elevation of 2.5 metres above the Australian Height Datum Capture by directly digitised from orthorectified imagery using specialist 3D terrain model interpretation software or scan and digitise from existing mapping and adding the height as a third dimension (Z).
| INDEX CONTOUR Definition: Being every fifth Intermediate Contour - classified as Feature Type “Index Contour” e.g., elevation values of 5m, 25m, 50m, 75m Alternate Terms: Major Contour | Capture as a 3D polyline along the feature Capture with a contour interval of 5 metre Being every fifth Intermediate Contour - classified as Feature Type “Index Contour” e.g., elevation values of 5m, 25m, 50m, 75m.
| INTERMEDIATE CONTOUR Definition: Representing an imaginary line on the ground joining points of equal elevation above the Australian Height Datum, showing increasing and decreasing elevation values at 5 metre intervals. Alternate Terms: Basic Contour | Capture as a 3D polyline along the feature Capture with a contour interval of 5 metre Capture by directly digitised from orthorectified imagery using specialist 3D terrain model interpretation software or scan and digitise from existing mapping and adding the height as a third dimension (Z).
| INDEX IMPERIAL CONTOUR Definition: Being every fifth Intermediate Imperial Contour - classified as Feature Type “Index Imperial Contour” Alternate Terms: | Elevations were originally captured in feet and converted to the nearest metre. Being every fifth Intermediate Imperial Contour captured by the appropriate process - classified as Feature Type “Index Imperial Contour”.
| INTERMEDIATE IMPERIAL CONTOUR Definition: Representing an imaginary line on the ground joining points of equal elevation above the Australian Height Datum, showing increasing and decreasing elevation values at 5 metre intervals. These elevations were originally captured in feet and converted to the nearest metre. Alternate Terms: | Elevations were originally captured in feet and converted to the nearest metre.

AUXILLARY CONTOUR Definition: – An additional contour used to aid relief interpretation over flatter or unique terrain,usually half the standard contour interval. The chosen values are of equal elevation above the Australian Height Datum. Alternate Terms: Supplementary Contour | Capture as a 2D polyline along the feature Capture at an elevation of 5 metres above the Australian Height Datum Auto-generate from the Shuttle Radar Topographic Missing (SRTM) digital terrain model where a 5 metre contour that has been captured using higher accuracy source data does not exist If a 5 metre contour captured using higher accuracy source data does exist, that data is to be incorporated into the feature class
