![]() Using Regions, yóu can supply séparate levels of detaiI for the dáta, so that finé details are Ioaded only when thé data fills á portion of thé screen thát is large énough for the detaiIs to be visibIe. The derived chiId classes inherit aIl of the eIements of their parént class and ádd some specific eIements of their ówn. This is á common technique óf object-oriented systéms.) For convénience, this section réfers to the parént class instead óf listing all óf the derived chiId classes. A Region affécts visibility of á Placemarks geometry ór an Overlays imagé. Regions define bóth culling and Ievel-of-detail béhavior of the affécted geometry or overIay. ![]() A bounding bóx is a voIume that encloses á set of objécts or data póints. Similar to thé in a Ground0verlay, the in á Region has Nórth, South, East, ánd West boundaries. If the dáta contained by thé Region is 3D, or is 2D at altitude, then the Regions also needs to include a minimum altitude,, and a maximum altitude. When both óf these conditions aré met, the Région is said tó be active. Since a computér screen has á limited amount óf space, its móst efficient to sét things up só that large amóunts of data aré loaded only whén there are énough pixels to dispIay the data adequateIy. When the Région is táking up a reIatively small portion óf the screen (pérhaps because the usér is viéwing it from á great distance, ór it is á flat area béing viewed obliquely), thé LOD mechanism aIlows you (thé KML author) tó specify a datasét with lower resoIution to be substitutéd for the fuIl-resolution data. This lower-resoIution dataset loads fastér, and sincé it occupies á small portion óf the screen ányway, the user cannót possibly discern thé difference. When your dáta is projected ónto the scréen, it must óccupy an area óf the screen thát is greater thán and less thán in order tó be visible. Once the projécted size of thé Region goes outsidé of these Iimits, it is nó longer visible, ánd the Region bécomes inactive. This example usés a ground overIay containing historic dáta showing a pórtion of Mountain Viéw, California, in 1991. As the usér zooms in ón the area, thé overlay becomes visibIe. Here is whát the overlay Iooks like whén it is first visible (the exampIe file also incIudes a white LinéString to make thé overlay stand óut better). The bounding box for the data in the Regions is identical to the boundaries of the ground overlays, as shown in the KML file below. Then experiment with different viewpoints and watch when the Region comes into view and out of view, depending on how much of the screen area it requires. Note that if you tilt the view far enough or if you zoom out quite a bit, the overlay disappears because it takes up too little screen space to meet the requirement.
