GeoGroup[geoobjects]

represents a list of geographic objects to be treated as a single object for certain operations.

Details

  • Geographic functions that can be used with GeoGroup include GeoDistance and GeoNearest.
  • geoobjects is a list that may contain geo position specifications; Entity objects with domains such as "Country", "City", and "AdministrativeDivision"; entities that have natural geographic positions; EntityClass objects of these types; or other geo groups.
  • GeoGroup allows distance computations to be performed efficiently.

Basic Examples  (2)

Display a grid of country-country distances between pairs of countries:

Wolfram Language code: Grid[{#, GeoDistance@@#}& /@ Subsets[{Entity["Country", "UnitedKingdom"], Entity["Country", "Spain"], Entity["Country", "Germany"]}, {2}], Dividers -> All, Alignment -> Left]

Find the (closest) distance between the United Kingdom and two other countries:

Wolfram Language code: GeoDistance[Entity["Country", "UnitedKingdom"], GeoGroup[{Entity["Country", "Spain"], Entity["Country", "Germany"]}]]

Make a list of large cities in Germany:

Wolfram Language code: cities = CityData[{Large, "Germany"}]

Efficiently compute the distance from Paris to the closest large German city:

Wolfram Language code: GeoDistance[Entity["City", {"Paris", "IleDeFrance", "France"}], GeoGroup[cities]]

Find the names of the closest large German cities:

Wolfram Language code: GeoNearest[cities, Entity["City", {"Paris", "IleDeFrance", "France"}], 5]

Compare with the results obtained by computing each distance separately:

Wolfram Language code: TakeSmallestBy[Transpose[{GeoDistance[Entity["City", {"Paris", "IleDeFrance", "France"}], cities], cities}], First, 5]

Properties & Relations  (1)

The default behavior of the geo style "Image" is to apply the image as a texture to individual polygons:

Wolfram Language code: euros = [image]; eurozone = EntityList[EntityClass["Country", "Eurozone"]]

Show the result of using the "Image" style on the eurozone countries:

Wolfram Language code: GeoGraphics[{GeoStyling[{"Image", euros}], Polygon /@ eurozone}]

GeoGroup can be used to apply the "Image" geo style to a geographic group as a whole:

Wolfram Language code: GeoGraphics[{GeoStyling[{"Image", euros}], GeoGroup[Polygon /@ eurozone]}]
