Spatial data minimum requirements for clearing applications

Spatial data is considered a minimum requirement for the acceptance of an application to clear native vegetation.

An application must include two spatial data files (preferred format: shapefile):

  1. clearing footprint (single part polygon) containing all of the proposed clearing areas
  2. land type map (single part polygon) containing all land types within and immediately beyond the boundaries of all proposed clearing polygons.

The preferred format is shapefile.

Spatial data

Spatial data for land clearing should include:

  • coordinate system: Geo-graphics – Geocentric Datum of Australia 1994
  • x, y coordinates only (z and m coordinates removed)
  • polygons snapped (i.e. the removal of all snippets and overlaps)
  • no white spaces (text variables)
  • no spelling errors
  • area calculated in hectares (preferred: GDA94 Australian Albers projection).

Clearing footprint minimum attributes

Minimum attributes for a clearing footprint spatial data include:

  • OBJECT ID – this is an automated field
  • Reference name – each polygon must have a unique reference name (i.e. paddock name)
  • Proposed use – proposed use of each polygon
  • Area ha – area of each polygon calculated in hectares (preferred projection: GDA94 Australian Albers).

See example in the table below.

OBJECTID Reference name Proposed use Area ha
1 Paddock A Improved pasture 67.25
2 Paddock BImproved pasture 0.78

Land type map minimum attributes

Minimum attributes for land type map spatial data include:

  • OBJECT ID – this is an automated field
  • Land Type – land type classification
  • Description –  land type description
  • Land capability – suitability score
  • Area ha – area of each polygon calculated in hectares (preferred projection: GDA94 Australian Albers).

See example in the table below.

OBJECTID Land TypeDescription Land capability Area ha
1 A Rises, slopes 4 to 6% with a woodland of Corymbia bleeseri (glossy leaved Bloodwood); well drained shallow rocky, gravelly (Rudosol) soils. Sandy surfaced. Hard rock at 40cm. 4 0.78
2 B Plains, slopes 0 to 2%, nil rock with Eucalyptus miniata (Woolybutt); Eucalyptus tetrodonta (Stringy Bark) with deep well-drained red (Kandosol) soils. Sandy surfaced to sandy clay loam at 1.0m. Significant gravel from 1.0m. 2 3.2
