Multi Attribute Data - Tweed River Catchments - Landform and Condition Dataset

Brief description

The multiple attribute mapping process provides a vector based inventory of the landscape in
terms of slope, terrain, landuse, vegetation, presence of tree regrowth, tree and shrub canopy
density, presence of understorey, soil erosion condition, and rockiness. Mass movement and
soil conservation measures are mapped where they exist, as is a selected range of weed
species. These characteristics of the land are part of the larger set of characteristics that can
be mapped using the NSW Dept. of Land and Water Conservation's full set of attribute codes.
This set of codes are termed the Standard Classification for Attributes of Land (SCALD). The
value of the attribute mapping is that the data objectively characterises the land and can be
used for a range of land uses and land management purposes. This system of mapping
maximises the efficiency of GIS operation by describing a number of attributes into one
polygon, avoiding problems caused by overlaying of different data sets.
Mapping is carried out at 1:25000 scale using base maps from the NSW Land Information
Centre medium scale topographic series. Outputs are most useful at the sub-catchment or
regional scale but not at property level. The data are extremely valuable at the river basin scale
for integrated catchment planning programmes The information can, however, be useful as a
first level of information in property planning exercises.
