The capability of multidate, multispectral ERTS-1 imagery of three different rangeland areas within Australia was evaluated for its
usefulness in preparing inventories of rangeland types, assessing on a broad scale range condition within these rangeland types, and
assessing the response of rangelands to rainfall events over large areas.
For the three divergent rangeland test areas, centered on Broken W, Alice Springs and Kalgoorlie, detailed interpretation of the imagery
only partially satisfied the information requirements set. It was most useful in the Broken Hill area where fenceline contrasts in range
condition were readily visible. At this and the other sites an overstorey of trees made interpretation difficult.
Whilst the low resolution characteristics and the lack of stereoscopic coverage hindered interpretation it was felt that this type of imagery
with its vast coverage, present low cost and potential for repeated sampling is a useful addition to conventional aerial photography for all
rangeland types.
