Perth, WA

Description

National satellite-derived fractional ground cover products (percentage of green vegetation, dry vegetation, bare soil) are now routinely produced by Geoscience Australia and other groups, and are available for interpretation. The extensive coverage, frequent repeated observations and large archive of historical imagery supports more objective and reproducible methods than previous degradation monitoring efforts that were based on intermittent field surveys of land condition and anecdotal reporting. Landsat (30-m pixel resolution) seasonal composite images will be used to estimate total ground cover throughout the year, and assess the proportion of cropland in the grainbelt below recommended cover thresholds of 50% for wind erosion, and 70% for water erosion.
