GeoVariant
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.
