SuperMap DETAILS:
Offshore Charts:
Select Offshore Charts from SuperMap's Details function. You will see the blue waters transform into a topographic chart very similar to the ones you'd buy at a tackle or retail store. You get the lat & lon lines, depths, fish havens, obstructions, missile test areas, cautions, restricted areas, just to name a few.
Latitude / Longitude Grid:
This feature does exactly what the name implies - lat and lon lines appear on the map.
Bathymetry Color Relief:
Bathymetry basically means the topography of the sea floor. It measures ocean depth. Zoom into the SuperMap Bathymetry Color Relief and you can see this much better.
Bathymetry Contours:
This feature shows the contour lines of the sea floor. You also see depths displayed along some lines. If you select Contours AND Color Relief, you will get one awesome Bathymetry display. Remember to zoom into the map to get the best results.
AWOIS Shipwreck Survey:
Select AWOIS Shipwreck Survey. (AWOIS stands for Automated Wreck and Information System.) Your map screen will be covered in shipwrecks! Single click on each ship graphic and you get a description of it. If the GPS coordinates are not in the description box, you can always grab the numbers by zooming in a bit and then pausing your mouse over the graphic. In the lower left of your map screen, you will see the lat lon coordinates. Just remember that the AWOIS contains data of low quality - so just because AWOIS says its there does not mean you will find anything.
In 1981, the National Ocean Service implemented the AWOIS to assist in planning hydrographic survey operations and to catalog and store a substantial volume of reported wrecks and obstructions that are considered navigational hazards within U.S. coastal waters. AWOIS contains information on over 10,000 submerged wrecks and obstructions in the coastal waters of the United States. (Source:NOAA) However, AWOIS information on known shipwrecks is known to be of low quality. It is intended for recreational and informational reading, and not for navigation.
