Inherits: Marble.GeoDataObject → Marble.GeoNode
Subclasses: Marble.GeoDataLatLonAltBox
Namespace: Marble

## Detailed Description

A class that defines a 2D bounding box for geographic data.

GeoDataLatLonBox is a 2D bounding box that describes a geographic area in terms of latitude and longitude.

The bounding box gets described by assigning the northern, southern, eastern and western boundary. So usually the value of the eastern boundary is bigger than the value of the western boundary. Only if the bounding box crosses the date line then the eastern boundary has got a smaller value than the western one.
