A Customization of the Arc Marine Data

Model to Support Whale Tracking via

Satellite Telemetry (Brett Lord Castillo)

The Operations group is divided into two areas,

Cruise and Approaches (Figure 7).

Cruise involves a small number of generic object classes to link field observations to the

person making the observation.

Approaches handle the specific operational situation of

approaching an animal and deploying a tag.

Cruise is essentially a customization of the Arc Marine SurveyInfo object class tables.

SurveyInfo links an InstantaneousPoint to a unique survey operation.

This point may

represent a sighting, photograph, deployment, telemetry location, or a wide variety of

other features.

When this point is linked to a survey though, that survey has a specific

crew, identified by CrewKey, and specific crew members in that crew, identified by the

Crew class object.

Thus, a crew has crew members and carries out one unique survey.

SurveyInfo is also a dimension of the ApproachEvent, a linking dimension table for the

Approach object group.
