Differential Global Positioning System

An enhancement to Global Positioning System (GPS) that uses a network of fixed ground based reference stations to broadcast the difference between the positions indicated by the satellite systems and the known fixed positions.

The underlying premise of differential GPS is that any two receivers that are relatively close together will experience similar atmospheric errors. DGPS requires that a GPS receiver be set up on a precisely known location. This GPS receiver is the base or reference station. The base station receiver calculates its position based on satellite signals and compares this location to the known location. The difference is applied to the GPS data recorded by the second GPS receiver, which is known as the roving receiver. The corrected information can be applied to data from the roving receiver in real-time in the field using radio signals or through post-processing after data capture using special processing software.

Domestic purposes are defined in the dictionary of the Water Act 2000 (Qld) (Schedule 4). While not stated explicitly, domestic purposes includes water used in connection with a residential dwelling including human consumption, cooking, toilets and showers etc. Watering of gardens up to 0.25 ha in size is also considered to be domestic use provided the produce from the garden is not grown for sale, barter or exchange.

This definition applies to:

Representation of the catchments of major surface water drainage systems, generally comprising a number of river basins. In Australia, 12 drainage divisions were first defined in the 1960s by the Australian Water Resources Council. Australian drainage division boundaries were revised by the Bureau in 2010 in line with the creation of the Australian Hydrological Geospatial Fabric (Geofabric) based on the 9 second Digital Elevation Model.

This definition applies to:

All non-irrigated crops including cereals, oil seeds, sugar and legumes.

This definition applies to:

All non-irrigated horticulture excluding intensive horticulture (e.g. glasshouses and shadehouses), which falls into the intensive use category. This category includes both perennial (e.g. tree fruits, tree nuts and vine fruits) and seasonal (e.g. fruits, nuts and herbs) horticulture.

This definition applies to:

All non-irrigated pastures including grazing modified pasture, exotic pasture, native pasture, woody fodder plants, pasture legumes and sown grasses.

This definition applies to:

Excessive salts in the soil surface and groundwater in non-irrigated areas. Although salts are a natural part of the Australian landscape, dryland salinity refers to excess salt that affects soil, native vegetation, biodiversity, crops and water quality.
