NSW Transport Facility Point Dataset - NSW Road Associated Structures
Transport facility point represents a facility related to transport. It is a point feature class of the NSW Digital Topographic Database ( DTDB), within the Transportation theme. A transport facility can be an airport, bus interchange, helipad, marina, parking area, railway station, roadside rest area, roadside emergency telephone or heavy vehicle checking station. These are stored in the class subtype attribute field in the dataset. There is no overall accuracy reported in the database, however accuracy of the individual feature instances of each feature class can be found in the database tables. The currency of the feature instances in this dataset can be found in “feature reliability date” or “attribute reliability date” attributes. All feature instances in this class are attributed with a planimetric accuracy value. It is expected that the 90% of well-defined points with the same planimetric accuracy are within 0.5mm of that map scale. Depending on the capture source, capture method, digital update and control point upgrade, every feature instance reported has a positional accuracy within the range of 1m - 100m. For detailed definitions on all feature classes and attributes, refer to the DTDB Data Dictionary.
