TunnelData

For general access to the Wolfram Knowledgebase, use entities of type Tunnel instead of TunnelData.

TunnelData[entity,property]

gives the value of the specified property for the tunnel entity.

TunnelData[{entity1,entity2,…},property]

gives a list of property values for the specified tunnel entities.

TunnelData[entity,property,annotation]

gives the specified annotation associated with the given property.

Details

  • TunnelData[] gives a list of all tunnel entities.
  • TunnelData["Properties"] gives a list of available properties.
  • TunnelData["SampleEntities"] gives a list of sample entities.
  • The specified entity in TunnelData can be an Entity, EntityClass, entity canonical name, or list thereof.
  • The specified property can be an EntityProperty, EntityPropertyClass, property canonical name, or list of properties.
  • Properties that do not apply or are not known in a particular case are indicated by Missing[…].
  • Properties include:
  • "Cities"city location
    "ConstructionEndDate"completion year
    "Countries"countries
    "Image"image
    "Length"total length
    "Name"name
    "Position"coordinates
    "Type"type

Basic Examples  (3)

Use for entity discovery:

Wolfram Language code: ["Channel Tunnel"]

Use to discover properties of a tunnel:

Wolfram Language code: ["How long is the Lincoln Tunnel in NYC?"]

Compare properties of multiple tunnels:

Wolfram Language code: lengths = SortBy[TunnelData[TunnelData["SampleEntities"], {"Name", "Length"}], Last];
Wolfram Language code: BarChart[lengths[[All, 2]], ChartLabels -> lengths[[All, 1]], BarOrigin -> Left, AxesLabel -> Automatic]

Neat Examples  (1)

Generate a map of notable tunnels near New York City with picture tooltips:

Wolfram Language code: GeoGraphics[{Blue, PointSize[.03], Tooltip@@@(DeleteCases[TunnelData[GeoNearest["Tunnel", [image], {All, Quantity[10, "Miles"]}], {"Position", "Image"}], {_, _Missing}] /. gp_GeoPosition :> Point@gp)} ]
