NSW Foundation Spatial Data Framework - Transport - Road Associated Structures

Various structural elements associated with the Road dataset.\r\n\r\nThe 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.\r\nRoad Bridge: a structure erected over a depression or obstacle to carry a road.\r\nRoad Tunnel: an underground or underwater road passage.\r\n\r\nFloodway: a section of road specifically designed to allow periodic or permanent subjection to water inundation.\r\n\r\nRoad Culvert: a masonry conduit which serves as a channel-crossing for water or a transport network beneath a road.\r\n\r\nFord: a shallow or flat portion of a bed of a watercourse where a crossing may be affected.\r\n\r\nNote the ‘ontype’ attributes of road-segment features mentioned above which have an obvious topological link to these features.
