Land use of South-West Victoria - Glenelg-Hopkins & Corangamite Region (Zone 54)

dataset: LANDUSE100_SW
This land use map has been prepared under contract with Bureau of Rural Sciences (BRS) for AFFA. The classification scheme followed here was the Australia Land Use Mapping (ALUM) classification version 5 (BRS, 2001). ALUM version 5 was developed by BRS as a modification of Baxter - Russell Classification, in coordination with State agencies. This product is based on information from Corporate Geospatial Data Library (CGDL), CAPAD and the planning maps from Infrastructure Department. This product has been field verified after two significant additions to the base product: (1) Agricultural land use classes based on satellite imagery, tree cover and the newly acquired field survey information, and (2) Updates on the intensive uses using aerial photographs where appropriate and field survey information. Product was independently validated. Overall accuracy is 87.46%.

(4) 2000-2001 Aerial Photography (1:15,000) from Infrastructure Department, Victoria and 2000-2002 Landsat Imagery (30m). (5) Fieldwork carried out May - October 2002 Dataset Originality: Derived 
Description
Processing Steps: A "draft land use" layer was created from data layers (1), (2) and (3), which consisted mostly of the non-agricultural areas. This was overlayed on the digital cadastre which was overlayed on the aerial photography and satellite imagery (4). The areas not covered by the "draft land use" were classified based upon aerial photograph / satellite image interpretation and/or field verification (5). This was performed by classifying cadastre parcels with a land use code. When classification of the cadastre was complete, merging of the cadastre layer with the "draft land use" layer was performed to produce one single land use layer.

Quality

Attribute Quality
Comments
The accuracy of the land use attributes has been determined through a validation procedure. Validation was carried out shortly after the completion of the land use data layer. 100 random sample sites were generated for every 1:100,000 map sheet in the 1:25,000 mapping areas and 50 points per 1:100,000 map sheets in the 1:100,000 mapping areas. The number of sample sites allocated to each land use was proportional to the area of each land use class in each validation area. Land uses at sample sites were recorded by independent observers. An error matrix was constructed for each validation area, comparing mapped land use to independently observed land use classes. The validation results produce an attribute accuracy of 87.46%. 
Positional Accuracy
Comments
25 - 100m 
Conceptual Consistency
Comments
All vector data sets were first checked against the cadastre layer for boundary accuracy. Attributes of layers were analysed according to land use definition and the relevant parts of the layers were extracted and merged together as one single layer. 
Missing Data
Comments
Land Use has been mapped across the full extent of the study area. Land use classes have been mapped down to a minimum secondary ALUM Version 5 level.
