Commodities data were produced as part of catchment scale land use mapping and primarily uses fine-scale satellite data and information collected in the field. Field validation was critical for mapping commodities.</SPAN></SPAN></P><P STYLE="margin:0 0 11 0;"><SPAN><SPAN>Jurisdiction captured commodity data (where possible) for those areas most recently mapped with a focus on horticulture and intensive animal industries. Other commodities which are tertiary classes of the ALUM classification (such as sugar cane, cotton, rice, olives and grapes) have been mapped by jurisdictions for some time and are included in this dataset. The source year (2002 to 2020), date of mapping (2008 to 2019) and scale of mapping (1:5,000 to 1:250,000) vary, reflecting the source data, capture date and scale. It is important to note that the location of a commodity may change on an annual basis, depending on factors such as climate, markets or farming systems.</SPAN></SPAN></P><P><SPAN /></P></DIV></DIV></DIV> |
