The data set represents all known public roads in the Northern Territory and most private ones of significance and is attributed with: Unique Identifier Category (heirarchy) Excluded (from Title) Road Name Road Name Type Road Name Suffix Centreline Source Type Centreline Source Data Centreline Source Date Place Names Register ID Roads Information Management System ID Directions of Travel Number of Lanes Left Number of Lanes Right Surface Type Divided Road Road Status (useage) Ground Relationship National Route Number State Route NumberEnglish-26-101291381998-01-02datasetnot knownNew roads will be added as they come to our attention, as will new alignments to existing ones.0not knownEach 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. 0not knownPositional 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.0not knownSome 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.0The 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.
