Transport

Crossings

Description

Crossings are structures built to facilitate the movement over, under or through another physical feature. In the Transport Theme, crossings include bridges, tunnels, fords, culverts and boardwalks.

Purpose

Crossings provide connection with the road, railway, footpath, river or other feature which structures are built on to facilitate transport over or under another physical feature.

Dataset Uses

• Routeing, traffic flow management and economic analysis
  • the development of routeing road networks for use by freight and logistics companies, emergency service / response authorities, and general public includes: shortest distance, fastest time and presence/absence of obstacles or restrictions depending upon mode of transport - name, structure, weight/height/speed limits or some other weighting
  • predicting, analysing and modelling traffic flows, accidents, when joined with business or statistical information - may only need a list by name, but possibly also location and intersection with other roads, railways, etc.
• Context for other location information
  • context for other features over local or small project areas - may show location, name, surface and user access
  • context for other features on topographic maps, or other regional or national tourist maps - usually name, class, surface, and route number, obstacles or barriers
  • context for charts and reference maps - generally only the location of higher order roads shown
• Asset management, infrastructure protection and public safety
  • asset management systems by roads authorities
  • identification of infrastructure vulnerable to different hazards
  • funding to improve safety at dangerous locations
• Service provision
  • Being able to calculate the remoteness of communities by comparing a location to the nearest urban centres, particularly to identify areas poorly served by medical facilities
  • funding determinations for infrastructure investment

Current Status

In each jurisdiction, the land management or mapping agency creates and manages datasets representing the location of a crossing. This information may be integrated from data held by transport authorities, derived from GPS data, roads defined in the cadastre, or from interpretation from satellite or airborne imagery.

Until 2006, data captured under Commonwealth mapping programs was not integrated with state and territory datasets. Since 2006, data captured in collaboration with the Commonwealth under the National Topographic Information Coordination Initiative will also be incorporated into state/territory datasets – these are mostly crossings in rural and remote areas which have not been revised for up to twenty years. As these are significant updates to a large number of crossings over large areas, these will take some time to be integrated into state and territory datasets.

There is currently no single vertical integration of all transport datasets, as listed, for the national coverage

Future Status

Short-term objectives

Provide a nationally consistent transport dataset which supports and delivers transport information through the vertical and horizontal integration of the listed datasets. This will allow linking of location of these features across all themes.

Dataset custodianship will sit with the relevant state and territory land management authority.

A national custodianship of the national crossing dataset needs to be confirmed significant stakeholders including:

• Department of Infrastructure and Regional Development, as the lead Australian Government agency on transport and regional affairs
• Bureau of Meteorology, due to its role under the Commonwealth Water Act 2007 for water flow forecasting, modelling and prediction
• Commonwealth Grants Commission, due to its role in assigning funding to state governments through GST revenue
• Geoscience Australia, due to its role as the national mapping authority and its close collaboration with state and territory agencies in maintaining all topographic information, its role in maintaining information on exposure of infrastructure to hazards, and its underpinning role in providing spatial advice to other parts of Australian Government.
• Austroads, as the representative agency of transport authorities in Australia

The National Topographic Information Coordination Initiative will continue to address consistency issues in dataset content, and compliance with the ICSM Roads Data Model, by:

• Integrating the GEODATA Topo-250K data content into datasets managed by the states and territories, with subsequent aggregation by PSMA Australia
• Undertaking data capture programs to bring state and territory information up to the standard of the ICSM Roads Data Model content specifications
• National information products will be made available as web services

Medium-term objectives

• Crossings information included in national topographic mapping products will be derived from the datasets in states and territories
• Data held by transport authorities which is categorised as part of the foundation will be integrated with the foundation datasets
• Crossings will be captured no greater than 1m in urban areas and between 2m and 10m in remote areas if captured from imagery

Long-term objectives

• National information products will have near-real-time currency – crossings recently gazetted or proposed will be made available in the national product overnight
• All national information products will be available under open access arrangements (for example, by CCBY) at zero cost

Railways and Railway Stations

Description

Railways are transportation systems using one or more rails to carry freight or passengers. Railway stations are recognised stopping places where goods, vehicles or passengers may be transferred from one form of transport to the rail network, and vice versa. Railway stations can also include what are now called “intermodal transfer stations”.

Purpose

National railway database provides information that connects capital cities, metropolitan or suburban railway lines, down to access railways which provide access within properties

Dataset Uses

• Routeing, traffic flow management and economic analysis
  • the development of routeing road networks for use by freight and logistics companies, emergency service / response authorities, and general public includes: shortest distance, fastest time and presence/absence of obstacles or restrictions depending upon mode of transport - name, structure, weight/height/speed limits or some other weighting
  • fuel-efficient fleet management and self-drive vehicles - require full transport surface specifications including slope, camber, etc.
  • predicting, analysing and modelling passenger and freight vehicle movements, and accidents, when joined with business or statistical information for analysis. May only need a list by name, but possibly also location and intersection with other roads, railways, crossings etc.

Airports and Airfields

Description

Airports and airfields are defined by the International Civil Aviation Organisation as defined points or areas on land or water intended to be used either wholly or in part for the arrival, departure and surface movement of aircraft. ICAO uses the term aerodromes. Airports are generally facilities that have commercial passenger and cargo facilities.

Purpose

Airports and airfields include:

• Facilities licensed, certified or registered by the Civil Aviation & Safety Authority
• International airports as defined by the Australian Government's Department of Infrastructure & Regional Development
• Helipads and heliports
• Other landing strips not covered above, but useable as a place to land aircraft

Dataset Uses

Routeing, traffic flow management and economic analysis

• the development of routeing road networks for use by freight and logistics companies, emergency service / response authorities, and general public includes: shortest distance, fastest time and presence/absence of obstacles or restrictions depending upon mode of transport
• predicting, analysing and modelling pedestrian and freight movements and accidents, when joined with business or statistical information for information. May only need a list by name

Navigation Aids and Obstacles - Land

Description

Location, height and description of infrastructure, markers or other devices on land which may aid travellers in determining their position or safe course.

Purpose

This dataset is also known as vertical obstructions or vertical obstacles due to the importance of this information for aeronautical safety as pilots must chart courses that maintain a lowest safe altitude above on-ground obstacles.

Navigation aids and obstacles on land include:

• Transmission lines
• Buildings
• Radio towers and masts
• Skyscrapers and other tall structures
• Chimneys on power plants

Dataset Uses

Aeronautical navigation and safety

• Shows the location of obstacles which determine the safest lowest altitude for flying, in particular within 45km of an airport
• Freedom of manoeuvre in airspace for defence purposes

Land-based navigation and safety

• Used as a landmark for terrestrial navigation and in the delivery of emergency services in rural and remote areas

Current Status

The current national dataset is part of the 1:250,000 scale topographic mapping program. Sourced from satellite imagery and information supplied by CASA-endorsed publications, local government, tourist information and other volunteered information.

The database being brought up to date through funding and resources from Airservices Australia and Geoscience Australia expected release in mide 2014.

Captured and revised between 2011 and 2012 for a number of Geoscience Australia programs, including the Australian Solar Energy Information System, the National Exposure Information System and other energy infrastructure programs. Similar data is captured by state and territory mapping agencies in collaboration with local energy infrastructure owners and operators.

There is currently no single vertical integration of all transport datasets, as listed, for the national coverage.

Future Status

Short-term objectives

Airservices Australia is funding the redevelopment of a new vertical obstacles dataset based on that previously maintained by RAAF. This is expected to be completed by mid-2014.

Key Users

The Commonwealth has carriage for aeronautical navigation under the Civil Aviation Safety Act and Regulations 1978, and the Airports Act 1996.

Key Commonwealth stakeholders include:

• Department of Infrastructure and Regional Development, as the lead Australian Government agency on transport and regional affairs
• Civil Aviation & Safety Authority
• Airservices Australia
• Geoscience Australia, due to its role as the national mapping authority and its close collaboration with state and territory agencies in maintaining all topographic information, its role in maintaining information on exposure of infrastructure to hazards, and its underpinning role in providing spatial advice to other parts of Australian Government.

Industry stakeholders include national and regional airlines, charter services, emergency services and health service providers such as the Royal Flying Doctor Service.

Additional

Required for creation and maintenance:

Elevation information may be required to source heights.

Imagery may be required to confirm position. Location can also be determined from sub-parcel licencing in the cadastre.

The significance of land-based aeronautical hazards is dependent upon their proximity to airports and airfields.

Note: This dataset may become an information product profile depending upon agreement on other dataset profiles such as Buildings & Built Infrastructure and those to be developed for Elevation.
