Vicmap Vegetation - Tree Density 1:25,000 - Medium Density Vegetation

This dataset is a presentation of Medium density vegetation features derived from the Vicmap Vegetation - Tree Density dataset. The presence/absence dataset is grouped into three density classes (Dense, Medium, Scattered) by neighbourhood and proximity cell based analysis.

The process of grouping tree cover into density classes simplifies the representation of trees and reduces the complexity of the vector dataset. It is a particularly neat way of representing scattered tree cover. The original, ungrouped raster dataset is maintained as a separate dataset.

Classifying SPOT Panchromatic imagery for vegetation can be limiting as the panchromatic image only encompasses a small portion of the infrared part of the electromagnetic spectrum. However, the image sharpness and detail offered makes the trade off between spectral range and spatial resolution worth while for mapping tree cover at 1:25,000.

Tree cover is defined as woody vegetation greater than 2 metres in height and with a crown cover (foliar density) greater than 10 percent.
