ABSTRACT

This chapter presents the findings of a research project designed to map soil salinity in the irrigation region of southern New South Wales (NSW), Australia, using satellite imagery. The initial aims of the project were to map the spatial and temporal spread of soil salinity in dry-farming and irrigation farming regions and to evaluate and compare the rates of increase in salinity over a 10-year period. Landsat multispectral scanner (MSS) and thematic mapper (TM) imagery and in situ monitoring techniques were used for that purpose. Change detection in soil salinity would help in extrapolating the findings to the future, for better land-use planning and effective management of resources.
