Creating collection relationships (Maritime Charting)

In peer-to-peer relationships, no feature's existence is dependent on another. Collections are considered a type of peer-to-peer relationship and can be grouped into two different object classes: aggregations (C_AGGR) or associations (C_ASSO).

Association objects (C_ASSO) depict at least one feature that, when associated, better represents certain navigational situations. For example, a buoy that marks a wreck can be associated in S-57 to help the mariner see that a danger lies in the area. The buoy is not dependent on the wreck, nor is the wreck dependent on the buoy.

Aggregation objects (C_AGGR) are collections of features that form a higher-level collection object that better describes a system or defines a larger area. For example, an aggregation relationship can be used to form a traffic separation scheme from traffic separation lane parts, boundaries, and so forth. In the geodatabase, the collection object is stored in the PLTS_COLLECTIONS table, and its relationships to the features that make up the collection are stored in the PLTS_FREL table.

Steps:
  1. Start ArcMap.
  2. On the main menu, click Customize > Toolbars > Production Editing.
