Normalised difference vegetation index (NDVI) for all pastoral leases in Western Australia
NDVI information for every pastoral lease in Western Australia is now part of the Pastoral Remote Sensing (PRS) application.
PRS is updated every 2 weeks, and includes a lot more information of use to pastoralists:
For each pastoral station, there are 3 groups of information.
Seasonal ground cover imagery: the satellite information is presented in colour to show the variation on bare soil, photosynthetic (green) vegetation and non-photosynthetic (dry) vegetation. This is for the whole region, for a chosen season and year, and the map fills the screen.
Monthly ground cover data: is presented for the station's land systems as estimated bare earth %, dry vegetation %, green vegetation %, total vegetation % and satellite imagery for a chosen month of a chosen year. The land systems are in a table on the left hand side when this option is chosen, with the percentages and an icon leading to charts of the estimated monthly ground cover data.
Weekly data: is presented for the station's land systems as mapped normalised difference vegetation index (NDVI or greenness index) categories for the station land systems, NDVI satellite imagery for the region, and estimated total green biomass (TGB). The land systems are in a table on the left hand side when this option is chosen, with the TGB for the period chosen, and the change since the previous week. There is an icon leading to charts of the estimated monthly ground cover data.
High resolution imagery is being added to PRS, and will be available soon.
