Spatial data representing Victorian coastal lands which have the potential to contain coastal acid sulfate soil (CASS), i.e. it is prospective for CASS. This spatial data is used for triggering an investigation of a site where proposed activities risk disturbing CASS. Disturbing CASS is defined as causing oxygen to penetrate earth material that contains metal oxides either in sulfidic material or sulfuric material. Sulfidic material is soil or sediment that contains metal sulfides which oxidise to sulfuric acid in the presence of oxygen. Sulfuric material has either partially or completely oxidised metal oxides. This data was created to help avoid disturbing potential CASS. An explanation of Coastal Acid Sulphate Soils and their mapping is available on Victorian Resources Online: http://vro.depi.vic.gov.au/dpi/vro/vrosite.nsf/pages/soil_acid_sulfate_soils DOI 10.4226/92/58e723a645d1f
