Service Description:

The Vicmap Vegetation Tree Density dataset was created by applying a set of rulesets across the Vicmap Vegetation Tree Extent data when processing the pixel-by-pixel assessment. The rulesets are listed below:

Density classification	Radius for assessment	Rules	Minimum patch size	Additional step
Dense	8 metres (49 pixels)	If 21 or more pixels in the radius are classified as tree extent, the selected pixel is classified as Dense.	2 hectares	Gaps equal to, or smaller than 0.1 hectares are infilled.
Medium	15 metres (197 pixels)	If 10 or more pixels in the radius are classified as tree extent, the selected pixel is classified as Medium.	1 hectare	Gaps equal to, or smaller than 0.25 hectares are infilled.
Spare	30 metres (709 pixels)	If 9 or more pixels in the radius are classified as tree extent, the selected pixel is classified as Sparce.	1 hectare	Remove Sparse regions that are smaller than 1 hectare are removed.

Title: Vicmap Vegetation Tree Density (GDA2020)
Author: Vicmap_DELWP
Comments:
Subject: Vicmap Vegetation Tree Density consists of data created from the Vicmap Vegetation Tree Extent statewide dataset (20cm pixels). The dataset was generalised to 2m pixels and then clustering rules were applied to group the data into three density classes. These density classes are Dense, Medium, and Sparse and show the spatial separation of woody vegetation. This classification was a pixel-by-pixel assessment where a pixel was allocated a density classification based on neighbouring pixels. The raster dataset was then converted to the statewide Vicmap Vegetation Tree Density vector dataset.
