Example

1. A small building is identified by a Point Feature. It has a Feature Node that defines its location, Classification Data that identifies it as a building, and a set of Property Values that describe its characteristics, such as its height and its building functional category.

FAQs

Can a Point Feature consist of multiple Feature Nodes?

No. A Point Feature must consist of only a single Feature Node.

Image_Mapping_Function

 Added to support "attributes for derived objects."
 That is, these components are used only to specify
 texture mapping information for geometry that
 is derived from the <Feature> by the consumer.
 These <Image Mapping Functions> must use
 <Image Anchor> components to specify the mapping.
