The derived "child" classes inherit all of the elements of their parent class and add some specific elements of their own. Note: In KML, some classes are derived from a "parent" class. Using Regions, you can supply separate levels of detail for the data, so that fine details are loaded only when the data fills a portion of the screen that is large enough for the details to be visible. Data is loaded and drawn only when it falls within the user's view and occupies a certain portion of the screen. Regions are a powerful new KML feature that allows you to add very large datasets to Google Earth without sacrificing performance. Here are some of the major new elements you'll be introduced to in KML 2.1: Forcing Data Refresh at a Specified Date/Time (uses new expiration feature).A University Landmark (3D COLLADA model with textures modeled in SketchUp).Importing Historical Imagery: Mountain View DOQQ, 1991 (very large dataset, split into subregions loaded with NetworkLinks).Radio-button folders - To allow the user to select only one item in a folder at a time, use the new ListStyle element to specify a radioFolder.Expiration date/time - You can specify a dateTime to refresh data so that the cache is flushed and data remains current.

Incremental updates - Now you can incrementally update data loaded by NetworkLinks-changing, adding, and deleting KML data that was previously loaded into Google Earth.Textured 3D models- 3D objects can be modeled naturally in their own coordinate space and exported as COLLADAâ„¢ files, then imported into Google Earth and placed on the Earth's surface.You can also simulate Google Earth's layers using Regions. When used with NetworkLinks, Regions enable streaming of very large datasets, with "smart" loading of data at multiple levels of resolution (see the section on Super-Overlays). Regions - Regions provide culling and level-of-detail behavior that allow you to fine-tune how your data is presented in Google Earth.See the KML 2.1 Reference and KML 2.1 Schema for details on elements discussed here.
