State Vegetation Type Map: Western Region v1.0. VIS_ID 4492

The NSW Office of Environment and Heritage (OEH) is producing a new map of the State’s native vegetation. This seamless map of NSW’s native vegetation types will enable government, industry and the community to better understand the composition and the relative significance of the native vegetation in their local area. The State Vegetation Type Map (SVTM) (http://www.environment.nsw.gov.au/vegetation/state-vegetation-type-map.htm) is constructed from the best available imagery, site survey records, and environmental information.

The primary thematic layer in this dataset is a regional scale map of Plant Community Type (PCT) - "quickview" map. This Version 1.0 release is comprehensive revision of the interim version 0.1 released in 2016.


A summary of the revisions are listed below:

  • An established one-to-one relationship between PCT and Vegetation Photo Pattern (vegStruct)
  • Integration of existing mapping, including:

    • VIS_ID 4186 - Survey and mapping of Darling floodplain vegetation communities in 2014
    • Balonne mapping 2016 (VIS_ID 4453)
    • Darling mapping 2016 (VIS_ID 4454
  • Manual revision of Vegetation Photo Pattern (VPP’s, vegStruct) with Aerial Photo Interpretation of time series enhanced time-series 2.5m SPOT 5 imagery

  • Reprojection of PCT models across updated VPP’s.

QuickView map fields:

  • PCTID – Plant Community Type identifier.
  • PCTName – Plant Community Type common names
  • vegClass – The PCT’s Keith Class
  • vegFormation – The PCT’s Keith Formation
  • mapSource - The source of the polygon’s PCT attribution.
  • MapName – The 100k sheet map name

Note that this is a dissolved surface and does not highlight the fine internal line-work within each map unit. Please refer to the 100k full data sheets for the complete editable internal linework, available by request from the Data.Broker@environment.nsw.gov.au.


The 100K full data fields are shown below:

  • polygonID – Unique map polygon identifier
  • PCTID – Plant Community Type identifier.
  • PCTName – Plant Community Type common names
  • vegetationClass – The PCT’s Keith Class
  • vegetationFormation – The PCT’s Keith Formation
  • mapSource - The source of the polygon’s PCT attribution. Possible values are:

    • Existing Mapping VIS4186
    • Site Survey (a site survey exists)
  • PCTIDMod1 - The most likely Plant Community Type identifier as derived from the spatial model.

  • PCTIDMod2 - The second most likely Plant Community Type identifier as derived from the spatial model.
  • PCTIDMod3 - The third most likely Plant Community Type identifier as derived from the spatial model.
  • vegStruct - Vegetation Structural Class as derived from initial manual aerial photo interpretation. These values may have been changed during later PCT manual editing to maintain the one-to-one relationship between PCT and Vegetation Structural Class.

  • PCTmapAccuracyConfidence - Modelling Confidence for PCTIDMod1 – Note that this reflects the modelling surface (PCTIDMod1) only and may not reflect the confidence of the mapped attribution (PCTID). PCTallocationConfidence can only be accurately applied to the published map surface (PCTID) where mapSource = ‘Spatial Modelling’.

  • PCTSiteValidation - Type of field validation used to assess PCT reliability:
