Satellite Imagery & NDVI Mapping Applications for Agriculture
WEDDIN LGA 2016-2017
SATELLITE IMAGE COMPARISON (2016-2017)
The Weddin Shire covers an area of 3,410 km and is located in the central west of New South Wales. Agriculture is a main stay of the economy with broad-acre cropping, along with livestock production, occurring throughout the area.
A mosaic of paddocks containing various crops and pastures, along with other natural features, can be observed using satellite imagery. This imagery can show the changing landscape throughout a season, as well as from year to year. This variability was especially evident in recent seasons.
2016 and 2017 were characterised by exceptionally wet (2016) and exceptionally dry (2017) growing seasons. Only 183mm (62%) of the average growing season rainfall fell between May and October in 2017 compared to 615mm (219%) in 2016.
The following series of maps feature satellite imagery from the Weddin Shire.
