GLOSSARY
Additions
Represents an increase in the area or value of the stock of land. These changes could be due to purchases of land for other uses, reassessment of land type or natural encroachment of other land covers.
Cadastre
A comprehensive record of the location, extent and shape of land parcels and associated identifiers that link parcels to records of ownership, occupancy, valuation or other administrative or legal information.
Closing stock
Physical or monetary stock at the end of an accounting period.
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.
Grid
Parallel and perpendicular lines superimposed on a map.
Land cover
Land cover refers to the observed physical and biological cover of the Earth’s surface and includes natural vegetation and abiotic (non-living) surface.
Land use
Land use reflects both (a) the activities undertaken and (b) the institutional arrangements put in place for a given area for the purposes of economic production, or the maintenance and restoration of environmental functions.
Natural Resource Management regions
56 regions across Australia based on catchments and bioregions. Fifteen of these regions fall within Queensland.
Net Change
The change in physical or monetary units that can be positive or negative. It is important to understand that net changes are highly aggregated and need to be used with care. For example, if 100 hectares of livestock grazing is lost in one place but added elsewhere, then no net change would be shown across the reporting region.
Opening stock
Physical or monetary stock at the beginning of an accounting period.
Raster
A spatial data type that defines cells of equal size arranged in rows and columns, each cell contains a single value.
Rateable Value
The value of land including site improvements (such as levelling, retaining walls and clearing of timber) but excluding structural improvement. Rateable land is typically used for government rating purposes and land tax assessment.
Reductions
Represents a decrease in the area or value of the stock of land. These changes could be due to sales of land for other uses, reassessment of land type or natural encroachment of other land covers.
Revaluations
Changes in monetary units due solely to valuation changes over the accounting period.
Valuer-General
The Valuer-General is an independent statutory officer who oversees the land valuation system in each state and territory.
