Data Quality
Lineage:The current dataset was established from the earlier DCDB which contained all the known public roads in the Northern Territory and other more used roads combined with the NT Pastoral Roads, the PSMA Indigenous Roads and the Geoscience Australia 1:250,000 Geodata Roads data sets in January 2007. The DCDB data is being continuously updated with new alignments and attributes from such sources as new Cadastre, GPS observations, new mapping and imagery and the Roads Information Mangement System.
Positional Accuracy:Positional reference source type, source data and source date have been recorded as individual attributes since 2005. Prior to that depending on the source and currency it may range from a few metres to a number of kilometres.
Attribute Accuracy:Some attributes such as Category, Excluded, Name (including Type andSuffix), Place ID and National and State Route Numbers should be complete and accurate. Others such as RIMS ID, Surface, Status, Direction, Ground Relationship, Divided and Lanes Left and Right were only introduced in 2007 and are currently being updated in the stated order. When these attributes have been updated the vector lines themselves will be given direction with respect to the parcel street address.
Logical Consistency:Each record is a polyline map object extending between two intersections, a road end or a change in an attribute. Where appropriate there is connectivity between polylines.
Completeness:New roads will be added as they come to our attention, as will new alignments to existing ones.
