The various map classes return result classes when queried that contain metadata about the queried shape. The metadata fields that are returned by a given map class are enumerated in one or more enums that implement the DataFieldInterface. That interface includes an accessor that returns the FieldUnit of the field in question. The unit is a logical unit, such as "people", "dollars", and "percent".

The metadata fields that are returned by a given map class are enumerated in one or more enums that implement the DataFieldInterface. That interface includes an accessor that returns the FieldUnit of the field in question. The unit is a logical unit, such as "people", "dollars", and "percent".
This class enumerates the units used by the various AskGeo maps. All units are annotated with a human readable name (e.g, "kilometers" or "degrees"), and type (as specified by providing a FieldType e.g., FieldType.STRING or FieldType.FLOAT).
