Multi Attribute Data - Clarence River Catchment - Landform and Condition Dataset |
Abstract |
The multiple attribute mapping process as applied in this dataset provides a vector based inventory of the landscape in terms of landuse, vegetation, presence of tree regrowth, tree and shrub canopy density, presence of understorey and soil erosion condition. It is referred to as Land Condition Mapping. Mass movement is mapped where it exists as is a selected range of weed species. These characteristics of the land are part of the larger dataset of characteristics that can be mapped using the NSW Dept. of Land and Water Conservation's full set of attribute codes. Multi Attribute Data is a vector-based inventory of the landscape comprising polygon and linear features. This system of mapping can describe a number of attributes (such as slope, terrain, landuse, vegetation community, presence of tree regrowth, soil erosion, rock outcrops, geology, Great Soil Groups, weed species and soil conservation measures) in to one polygon. The value of attribute mapping lies in the fact that the data, which objectively characterises the land, can be used for a variety of purposes and is only limited by the scale of mapping and the classification used. This translates into the availability of a range of derivative products. Mapping is typically carried out at 1:25 000 scale using topographic maps as a base. Outputs are most useful at a sub- catchment or regional scale but not generally at property level. |

Lineage |
Multiple attribute mapping was developed from erosion/land use mapping carried out by DLWC and precursor organisations. It was developed to interact efficiently with GIS's to record a large number of attributes in a single assessment and to simplify the process validation of data during field inspections. Linework is based on aerial photograph interpretation by staff with backgrounds in natural resource assessment. Quality assurance procedures are in place to maintain standards in API, mapping and classification.Metadata imported.C:\Program Files\ArcGIS\Metadata\ANZMeta\Thesaurus\temp.xml2008021511390600Metadata imported.D:\MultiAttribute_Clarence.xml2008060409555800Dataset copied.\GRARO\GIS\gisdata_GDA94\NATRES.mdb2008082214572100 |

DQ Completeness Commission |
|
Effective date |
2009-01-10 |
Explanation |
Mapping is complete for private land tenure for the whole catchment. Mapping was not carried out on Crown Land due to the fact that the classification would be primarily be related to vegetative cover and the imminent availability of a more detailed vegetation dataset from the Comprehensive Regional Assessment (CRA). Mapping was carried out on 1:25 000 scale topographic maps using 1:25 000 aerial photography. Linear features less than 100m in length were not represented. Map legends are compact and standardised, carrying only limited descriptive information. Users of the data are urged to consult the Standard Classification for Attributes of Land (SCALD) for a full listing of the categories used and/or Landscape assessment Unit staff for assistance with interpretation of the data. |

DQ Conceptual Consistency |
|
Effective date |
1900-01-01 |
Explanation |
Logical consistency tests performed include label errors, overshoots, undershoots, polygonclosures and topological consistency. These tests ensure that all classified polygons areclosed, nodes are formed at the intersection of lines and that there is only one label withineach polygon, etc |

DQ Absolute External Positional Accuracy |
|
Effective date |
1900-01-01 |
Explanation |
The estimated positional accuracy of the linework is between 12.5m and up to 75mdependent on the intensity of pre-existing locational reference data (such as contours andcadasta,etc). Average minimum polygon size is approximately 2to 4 hectares but smaller units can be recorded for important point features. |
DQ Non Quantitative Attribute Correctness |
|
Effective date |
1900-01-01 |
Explanation |
Land characteristics are interpreted from aerial photophaphy by experienced Land Assessment Unit staff using the Departments standardised set of attributes (SCALD). SCALD definitions are based on Australian Standards where applicable or DLWC standards elsewhere. Field verification was carried out to check and correct identification.Standard DLWC edge matching procedures were carried out on all the tile joins for attributes. In the standard "land condition" dataset, land use is recorded as a single character alphabetic character followed by a two digit numeric code; vegetation is recorded as a five character field comprising a two digit numeric code followed by a single digit numeric code representing status of regeneration, a single alphabetic character representing canopy percentage classes, a single digit numeric code representing status of understorey; erosion is recorded as a three digit numeric code. Where recorded, mass movement is recorded as a four character numeric-numeric-alphabetic-numeric code and the status of any soil conservation measures implemented within a polygon is recorded as a single alphabetic code. |
