A region contains a bounding box () that describes an area of interest defined by geographic coordinates and altitudes. In addition, a Region contains an LOD (level of detail) extent () that defines a validity range of the associated Region in terms of projected screen size. A Region is said to be "active" when the bounding box is within the user's view and the LOD requirements are met. Objects associated with a Region are drawn only when the Region is active. When the is onRegion, the Link or Icon is loaded only when the Region is active. See the "Topics in KML" page on Regions for more details. In a Container or NetworkLink hierarchy, this calculation uses the Region that is the closest ancestor in the hierarchy.

Features and geometry associated with a Region are drawn only when the Region is active. See .

Field Detail

latLonAltBox

protected LatLonAltBox latLonAltBox

(required)

A bounding box that describes an area of interest defined by geographic coordinates and altitudes. Default values and required fields are as follows:

lod

protected Lod lod

(required) Measurement in screen pixels that represents the minimum limit of the visibility range for a given Region. Google Earth calculates the size of the Region when projected onto screen space. Then it computes the square root of the Region's area (if, for example, the Region is square and the viewpoint is directly above the Region, and the Region is not tilted, this measurement is equal to the width of the projected Region). If this measurement falls within the limits defined by and (and if the is in view), the Region is active. If this limit is not reached, the associated geometry is considered to be too far from the user's viewpoint to be drawn. Measurement in screen pixels that represents the maximum limit of the visibility range for a given Region. A value of −1, the default, indicates "active to infinite size." Distance over which the geometry fades, from fully opaque to fully transparent. This ramp value, expressed in screen pixels, is applied at the minimum end of the LOD (visibility) limits. Distance over which the geometry fades, from fully transparent to fully opaque. This ramp value, expressed in screen pixels, is applied at the maximum end of the LOD (visibility) limits.
