Mapping current land use from Landsat data in southern inland Queensland.

Abstract

Land use/cover maps were generated using digi~al analysis of Landsat Multispectral Scanner data for a section of the brigalow belt in southern Queensland. As most agricultural establishments in the study area combine beef and/or sheep with grain production, a complex land uselcover pattern is present. Because of this diversity the most efficient computer analysis strategy was found to be a combination of digital masking techniques and unsupervised classification. Five land use categories were identified from the Landsat data with an overall mapping accuracy of 91%.
