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

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