Mapping methodology

​Land use mapping procedures are outlined in the Guidelines for land use mapping in Australia; principles, procedures and definitions, 4th edition and the Addendum to the Guidelines for land use mapping in Australia: principles, procedures and definitions, 4th Edition. These guidelines provide procedure for planning and performing land use mapping at catchment scale. 

Firstly ancillary datasets are acquired, including reserves and administrative boundaries, cadastre, infrastructure and utilities, hydrology, transport and vegetation. These datasets are then spatially analysed and interpreted with imagery and verification and validation with expert knowledge through stakeholder engagements and field visits.

The development of a modelling process to partially create the dataset allows a repeatable process for future iterations of land use mapping. The land use mapping coverage is available for mixed dates at a scale that varies according to the intensity of land use activities and landscape context. 

The dataset structure, as shown below, is specified by ACLUMP and provides information about prime land use, commodity type, primary source of information (scale, date, data type, and confidence) and other comments.
