The capability of multidate, multispectral ERTS-1 imagery of three different rangeland areas within Australia was evaluated for itsusefulness in preparing inventories of rangeland types, assessing on a broad scale range condition within these rangeland types, andassessing 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 imageryonly partially satisfied the information requirements set. It was most useful in the Broken Hill area where fenceline contrasts in rangecondition 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 imagerywith its vast coverage, present low cost and potential for repeated sampling is a useful addition to conventional aerial photography for allrangeland types. |
