Satellite-derived vegetation indices applied to semi-arid shrublands in Australia

Auteur(s) et Affiliation(s)



Description :
In this study, a semi-arid shrubland in western New South Wales was used to test a number of vegetation indices developed from Landsat Thematic Mapper sensor data. Vegetation cover varied from a mean of 22% in mid-summer to a mean of 78% in mid-winter. There was no significant relationship between the Normalised Difference Vegetation Index (NDVI) and summer vegetation cover, though there was a significant relationship with total vegetation cover in winter. The Landsat Thematic Mapper vegetation indices most useful for monitoring vegetation in this semi-arid region are the Stress Related Index and the Australian Arid Rangelands Index.
