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.

NSW Coastline data is linear feature class defining the line of contact between a body of water and the land. In particular, the line delineating the interface between land, internal waters and the “Territorial Sea” as defined by the Seas and Submerged Lands Act - No. 161 of 1973. The coastline defining Mean High Water Mark (MHWM) does not include MHWM within estuaries. Features within coastline feature class include: mean high water mark and mean low water mark.

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.

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.

NSW Hydro Line defines the centreline of a water course. It includes features such as natural water course, canal-drain, race, spill way and tunnel-siphon. It includes key attributes such as hydro line name, perennially and flow direction.

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.
