The Data Centre

The Data Centre is the central interface of the software where the user can record, edit, and view vessel activity data. Activities are any operational actions performed by a vessel or its crew. They include fishing operations, non-fishing operations and observations of the environment and other phenomena around the vessel. Data can be entered in both real-time and historical modes.The data centre consists of a number of separate components which are used to record and view data hierarchically, geographically and chronologically.

	The Activity Tree All recorded vessel activities are shown in the activity tree. This is a hierarchical display showing all trips, sets (or tows) within in a trip, and day summaries for each day in a trip. All the trips of a vessel are listed beneath the vessel and can be captured in real-time or historically. All the sets that were completed during a trip are listed beneath the trip. Sets can be captured in real time or historically. A set is a generic name used in Olfish and covers the entire fishing operation, from setting of the gear to the hauling. A set corresponds to a tow. Day summaries are also shown above groups of sets that were captured during a day. Day summaries have to be added manually and are entered as historical data. Non-Fishing activities are shown in between the activities during which they occurred.			The Calendar All operational activities for which date and time was recorded are displayed on the calendar component. The calendar can show this information in a year, month, week, or day view. A coloured bar stretching from the start time to the end time of each activity is displayed. Every type of activity has a unique colour. The height at which the bar is plotted within each time cell is also different for each type of activity. Selecting an activity in the calendar highlights it on both the calendar and the tree display and summarised information on it is displayed in the browser. In order to save computer resources only a year’s worth of data is displayed in the data centre at any one time. The option to change the current year is available on the year view of the calendar.
	The Mapper The mapper is a GIS (geographical information system) component that displays a map of the world. The mapper spatially represents data captured in Olfish. It is not intended as a navigation or charting utility. A comprehensive set of viewing tools are provided. The user has the option to include several other layers of information such as; Bathymetry (sea bottom depth) data, Management areas, High resolution maps of continents, Any data that has a location tied to it. Information for the whole world is not included by default. The software can be customised by OLRAC to provide for the individual needs of a client depending on their company profile and the geographic locations in which they operate. Telemetry data for the selected activity is displayed spatially on the map. By default only single sets are displayed but the user has the option to display all the sets belonging to a trip as well. Real-time vessel tracking is also shown on the map. Other data displayed in the mapper include the last known vessel position, gear markers (indicating the deployment positions of traps, buoys, anchors and other gear during setting) and catch markers (indicating the positions of catches in longline fisheries).			The Browser The browser component is a reporting tool that displays summarised information on the activity selected on the tree, the calendar, or the mapper. Shortcut links are shown with all items that have associated editor screens. All related data relevant to a selected activity, including multimedia notes, are also shown in the summary. For example, the browser would show data on a selected trip, as well as all sets associated with that trip. For a selected set, the browser would show the following summary information: Operational data for each aspect of the set (setting, fishing, hauling); gear deployment information; any catches made during hauling; all observations made during the set; and all multimedia notes taken during the set.
	The Observation Component The observation component allows the user to record data on phenomena observed during any vessel activity. Three types of observations are currently catered for by the software - Environmental Marine Life and Debris observations.
