Quality

Conceptual Consistency

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

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. 

Attribute Quality

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%.

Lineage

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.
