Abstract : The management of the rangelands of Western Australia requires both range inventory and trend estimation. This paper reports the progress of an investigation into the use of Landsat digital data for these purposes. The overall aim of the study is to examine the relationships between Landsat digital data and the vegetative characteristics of some rangeland types from different communities in varying range condition. There is one strong canonical correlation between the Landsat bands and the vegetative characteristics, with the canonical vector for the Landsat bands reflecting a contrast between band 5 (B5) and either band 6 (B6) or band 7 (B7), and that for the vegetative characteristics being dominated by the proportion of green biomass (PG). The relationship between the difference B6-B5 and the vegetative characteristics explains virtually all of the relationship between the two sets of variables. Canonical variate analysis is used to discriminate between the pasture communities. Bands 5 and 7 give the best discrimination. Excellent allocation of individual pixels is achieved. Atypical pixels are identified and discussed.
