public interface ILcdGDFFeature
extends ILcdShape, ILcdDataObject

This interface describes general properties of a GDF Feature. Features are the basic building blocks of GDF models, and represent real world objects (e.g. roads, lakes, buildings, ...) All objects contained in models decoded by the TLcdGDFModelDecoder will implement this interface.
