As in Basic interoperability, data products to be loaded are selected as specified in the predefined combination selected by the mariner. The mariner may also select additional data products from the optional load set. Processing of feature data from products not listed in the interoperability catalogue, levels 0, 1, and 2 interoperability place as before. In level 3 processing, operations for suppressing feature instances (Suppress Feature Instances) are added, as are operations for hybridization of thematic attributes (Combine Thematic Attributes). Additional processing to adjust feature and information associations for remaining features may be needed and this is done in the Associations” stage. The order of processing steps is Suppress Feature “Combine Types Feature Instances ->Combine Thematic Attributes ->Interleave Feature Layers. In level 4 processing, any additional processing needed to generate spatial primitives for the output hybridized feature is done in the Combine Spatial Attributes stage between suppression of feature instances and combination of thematic attributes. The processing flow is Suppress Feature Types Feature Instances ->Combine Spatial Attributes ->Combine Thematic Attributes Feature Layers. It is depicted in the figure below. Figure 144 - Processing for advanced interoperability (interoperability precedes portrayal) Processing for the other implementation option (drawing instructions precede interoperability) the flow is similar with an additional step (Portrayal Processing) moved to immediately follow loading of data.
