GeoVariant[obj,qual]

represents a geographic object obj with qualifier qual.

Details

  • The geographic object obj can be an Entity object, an EntityClass object, or a string representing an entity type such as "Country" or "HistoricalCountry".
  • Possible qualifiers include:
  • Automatic region returned when no GeoVariant is specified
    "AllAreas"all legal territories (e.g. US including e.g. Guam)
    "Center"center
    "DefaultMapArea"area used for standard maps
    "MaximumArea"region of largest extent of a time-dependent entity
    "PrincipalArea"main territories
    "SimplifiedArea"low-resolution schematic region
    "TimeSeries"collection of regions of a time-dependent entity
    "UnionArea"union of all regions of a time-dependent entity
  • Geo variants can be used to qualify the geographical extent of geo entities, as well as to express how to treat historical entities in geo computations.
  • Unlike GeoGroup, which combines multiple entities, GeoVariant allows specification of a particular variant of a single entity.

Scope  (12)

Automatic  (1)

Show the default geo variant of the US:

"AllAreas"  (1)

Show all areas of the US:

"Center"  (1)

Show only a central point of the country:

"DefaultMapArea"  (1)

The geo variant "DefaultMapArea" denotes the default choice of polygons in GeoGraphics:

"PrincipalArea"  (1)

The geo variant "PrincipalArea" contains the main territories of a country:

"SimplifiedArea"  (1)

The geo variant "SimplifiedArea" contains only the largest main areas, and with fewer points:

"UnionArea"  (2)

The geo variant "UnionArea" is the union in time of all territories of a time-dependent entity:

Use Dated to restrict a time-dependent entity to a given range of years:

"TimeSeries"  (2)

The geo variant "TimeSeries" interprets a time-dependent entity as its collection of polygons in time:

Draw a map of the territory corresponding to year 200 BC:

Use Dated to restrict a time-dependent entity to a given range of years:

"MaximumArea"  (2)

The geo variant "MaximumArea" corresponds to the moment of largest extent of a time-dependent entity:

Use Dated to restrict a time-dependent entity to a given range of years:

The territories can be restricted by the use of Dated:
