Airport is a facility, either on land or water, where aircraft can take off or land. It usually consists of hard-surfaced landing strips, a control tower, hangars, and accommodations for passengers and cargo. This data is held and maintained within the NSW Digital Topographic Database (DTDB) and includes key attributes such as airport name.

Various other facilities associated with the Maritime dataset. The following are facility points and lines related to transport. Wharf: any structure on a waterfront designed to make it possible for vessels to lie alongside and take or unload cargo, passengers etc. Launching Ramp: a sloping construction to facilitate launching or retrieving boats from water. Marina: a facility for commercial and recreational craft where mooring, supplies, repairs, and various services are available.

Transport data is a representation of the land, water and air networks used to move people and goods, and deliver services, from one location to another. It includes network connectivity and characteristics such as type, name and potential restrictions on what can be moved through the network.

Various structural elements associated with the Road dataset. The following are ‘crossings’ being a point feature class representing structures that facilitate the crossing of a road or railway over, under or through another feature. Road Bridge: a structure erected over a depression or obstacle to carry a road. Road Tunnel: an underground or underwater road passage. Floodway: a section of road specifically designed to allow periodic or permanent subjection to water inundation. Road Culvert: a masonry conduit which serves as a channel-crossing for water or a transport network beneath a road. Ford: a shallow or flat portion of a bed of a watercourse where a crossing may be affected. Note the ‘ontype’ attributes of road-segment features mentioned above which have an obvious topological link to these features.

Imagery is the product created from the use of airborne, space borne or terrestrial sensors. These technologies image the surface of the Earth to allow for the visualisation of land surface features. Imagery includes data sourced from satellite, aircraft and vehicle mounted sensors. These technologies have a range of capabilities that includes but is not limited to, the ability to record multispectral and hyperspectral data and produce products such as orthorectified mosaics and stereo-viewable imagery.

Addressing is the specific identification of a fixed location (for example, a plot of land, building, part of a building, way of access or other construction) which is represented by a structured arrangement of place names. It may be further detailed with the inclusion of other valuable attributes including geocodes.
