As you can surmize, there are MANY power tools (and their dialogs!) in SeaScape – too many to include in a single PDF. But, here are a few that might interest you...

Newer Stuff in Version 5.63:

KML Output To Maps (Google Earth, etc.):

Besides the awesome mapping program called “OziExplorer,” SeaScape now also supports outputting to KML-based mapping systems like Google Earth, etc. All of SeaScape's graphical constructions (except Contours) may be specified in a manner similar to the OziExplorer support. (KML doesn't support color assignments within individual graphical primitives so drawing finely-colored contour lines is next to impossible.)

SeaScape's KML output also supports raster overlays of your chosen map to programs like Google Earth. An example of such an output with real data drawn on it shown below, zoomed out:

Fix tracks, navaid points (waypoints, anchors, area circles and acoustic array devices), various navaid line sets (tracklines, area boxes and regions), polylines (.PolyList), DXF drawings (.DrawingList), grid text (.GridText) and grid depths (.Depths) along with your choice of grid box are output as a single KML document with category folders (see above).

Point objects as KML “placemarks” may be scaled, colored and assigned symbols from SeaScape's “Custom Symbols.” If OziExplorer is also installed/licensed and running on the system, all of its standard symbols are included, as well (and that's a lot of symbols!). Similarly, color choices exist for fix tracks, line sets and grid text.

Refer to the revised “Output To Maps” dialog shown below. It is launched from the View Menu as before but is now labeled as “Output To Maps...” rather than “OziExplorer...”

For comparison, here's a real-life example of output to OziExplorer of an undersea cable lay:

Ray Path Plotter and Computation Engine:

Although technically new to Version 5.60 , SeaScape has a brand-new Ray Path Plotter that gets launched from the Acoustics Dialog: Water Column Tab as a separate window. It also has a completely revamped computational engine for determining acoustic ray paths, and thus, range reduction for both active and passive LBL modes.

New Ray Path Plotter

The new plotter is useful for general purpose analysis of acoustic propagation for all types of navigation: LBL, USBL and mooring calibrations, etc. For LBL-related range reduction, SeaScape now computes up to five regions of ray path behavior that can be automatically applied to the desired LBL method (synchronous-active, synchronous-passive, active ranging, and, passive array detection:

Computing the new, 5-region Range v. Time Correlation Matrix

Providing this new matrix helps resolve multiple possible ray paths with distinctly different arrival times, thus

improving the quality of the fix. An example of an actual Arctic water column with five unique propagation regions:

Synchronous LBL:
