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.

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:
