Extreme left is the climatology (environmental) data display which updates continuously as the mouse moves over the chart area. This display includes simple air-water interface parameters such as wind speed and air pressure but is mainly aimed at underwater features such as mixed layer thickness, depth excess and range to first convergence zone (CZ1).
The main chart area (centre) ranges in coverage from a Global chart to an area of approximately 1nm across. The chart is constructed using bathymetry data and, where high coastline definition is required, the World Vector Shoreline (WVS) at a scale of 1:100000.
A wide variety of overlays such as port locations or lat/long grid can be added to the chart to provide spatial orientation markers or additional relevant data. Users can also create their own overlay files to display on the main screen.
Extreme right is the water column & sediment displays which can show either temperature, salinity, sound speed or buoyancy frequency profiles, or, a sediment data ket with seabed reflection loss profiles. Each is updated as the mouse is moved over the chart.
Bottom left is the control used to select the chart area and WVS operations.
Bottom centre are the controls to select sonar range prediction displays using colour coded ‘blobby radial’ displays.
Bottom right are the controls for propagation loss overlay displays.
