5.5 Composite Module

The Composite module is used to transfer composite objects (see 2.3). It serves to transfer user-defined composite data in ways that cannot be accomplished with the Point-Node, Line, Polygon, Ring, Arc, or Raster modules alone. A composite object is composed of zero, one, or more other spatial objects, either vector or raster, simple or composite. Using this module, spatial objects are aggregated to make a more complex spatial object; therefore, composite objects do not carry any coordinate data within the module record (see Table 33).

Composite objects are given the Object Representation Code "FF".
