Vegetation Structural Properties & Biomass

An estimate of persistent green cover per season.This is intended to estimate the portion of vegetation that does not completely senesce within a year, which primarily consists of woody vegetation (trees and shrubs).

Two fractional cover decile products for green cover and total cover. These products compare, per-pixel, the cover for a specific season of interest against the long term cover for that same season. This can be used to identify areas of low or high cover, relative to what is normal at that location at that time of year.

Estimates of ‘true’ ground cover for each season, restricted to areas of less than 60% woody vegetation, by combining information from the Persistent Green and Seasonal fractional cover products.

Representative seasonal medians of fractional cover, with landcover fractions representing the proportions of green, non-green and bare cover. The benefits of compositing seasonal images are the creation of a regular time-series capturing seasonal variability, and the minimisation of missing data and contamination present in single date imagery.

A map product of woody-vegetation cover of Australia for the decade from 2000 to 2010, derived from field, airborne and satellite image data.

Vegetation fractional cover represents the exposed proportion of green, non-green, and bare cover within each pixel. Landsat-scale ground cover information is important for soil erosion and nutrient flux estimates into the stream network, as well as assessing the impact of human activities.
