GLOSSARY
Cadastre
A comprehensive National digital dataset of land parcels including their surveyed boundaries.
Centroid
The centre of a digital bounded area, for example an SA1. This point is assigned a set of latitude and longitude coordinates. In some cases, such as a crescent-shaped area, the centroid may lie outside the limits of the area. (Adapted from Census Dictionary, 2006)
Geocoding
Latitude and longitude coordinates for an address.
Geographic Information System (GIS)
A computer system or software capable of storing, manipulating, analysing and displaying spatially referenced information.
Land cover
Refers to the physical surface of the earth, including various combinations of vegetation types, soils, exposed rocks and water bodies as well as anthropogenic elements, such as agriculture and built environments. Land cover classes can usually be discriminated by characteristic patterns using remote sensing.
Land use
The purpose to which the land is committed. Some land uses, such as agriculture, have a characteristic land cover pattern. These usually appear in land cover classifications. Other land uses, such as nature conservation, are not readily discriminated by a characteristic land cover pattern. For example, where the land cover is woodland, land use may be timber production or nature conservation.
Natural Resource Management regions
56 regions across Australia based on catchments and bioregions. Fifteen of these regions fall within Queensland.
Statistical Areas Level 1 (SA1s)
The smallest region for which a wide range of census data will be released. SA1s have an average population of approximately 400 and are built from whole Mesh Blocks.
