Trajectory coverage A series of ResultValues for a single Variable, measured on a single SamplingFeature, using a single Method, with specific Units, having a specific ProcessingLevel, but measured over varying X,Y, Z, and D locations, where X and Y are horizontal coordinates, Z is a vertical coordinate, and D is the distance along the trajectory. ValueDateTime may be fixed (DTS Temperature) or controlled (glider). Coverage ODM2 Result Type Controlled Vocabulary ODM2 Working Group A vocabulary for describing the type of the Result. In ODM2 Results are separated from, but related to their data values. Each ResultType has a set of related tables for storing the data values for any result of that type.
