Soil and landscape constraint mapping system for land use planning

摘要

A series of soil and landscape constraint maps based on the relative costs of ameliorating on-site hazards as well as residual on-site and off-site risks have been developed for coastal NSW. The includes the objective ranking of multiple soil landscape qualities combined with digital elevation model technology, state-of-the-art erosion hazard modelling and Acid Sulfate Soil Risk mapping, all in a risk management netting. The resulting raster surfaces comprise 232 million pixels (25 X 25 m) and extendover 3.8 million hectares of the NSW Coast and provide unprecedented levels of spatial resolution to aid regional planning. The results can be readily interpreted by land use planners and land managers and should contribute to environmentally sustainable land use decision making in NSW coastal regions.
