NSW Digital Topographic Database
The NSW Digital Topographic Database ( DTDB) is a seamless state-wide digital representation of terrain, place names, and visible features on the Earth’s surface within NSW. It is one of the foundation datasets of the New South Wales (NSW) Spatial Data Infrastructure (SDI). There are four (4) themes within the DTDB: Cultural, Hydrography, Physiography and Transportation. The cultural theme consists of features whose primary characteristic are of a cultural (man-made) origin, but generally not including transportation related features. The hydrography theme consists of features whose primary characteristics relate to water or drainage networks. The physiography theme consists of features whose primary characteristics relate to land surface or land form. The transportation theme consists of features whose primary characteristics relate to transportation. There are a total of 42 feature classes included in the DTDB which consist of Aggregated Way, Aggregated Way Segment, Cableway, Classified Fire Trail, Crossing, Ferry Route, Railway, Road Segment, Road Name Extent, Runway, Traffic Control Device, Transport Facility Line, Transport Facility Point, Building Complex Point, Electricity Transmission Line, General Cultural Area, General Cultural Line, General Cultural Point, Pipeline, Place Area, Place Point, Points of Interest, Tank Area, Tank Point, Utility Water Supply Canal, Contour, DLS Area, DLS Line, DLS Point, Fuzzy Extent Area, Fuzzy Extent Line, Fuzzy Extent Point, Relative Height, Spot Height, Ancillary Hydro Point, Coastline, Fuzzy Extent Water Area, Fuzzy Extent Water Line, Hydro Area, Hydro Line, Hydro Point and Named Water course. Cableway, Coastline, Contour, Crossing, DlsArea, Electricity Transmission line, Ferry Route, Fuzzy extent area, general cultural area, Hydro area, hydro line, Named water course, Pipeline, Place area Place Point, Point of interest, railway, relative hieghts, roadsegment, runway, spotheights, tank area, tankpoint, traffic control device, utility water supply feature classes are available for online downloading with reduced attributes.For further information on each feature class and its attributes, refer to the respective metadata record or the Digital Topographic Database Data Dictionary. The Digital Topographic Database ( DTDB) is primarily used for resource management, environmental management, land use planning, agriculture management, emergency management and recreational purposes.
