28. Give 6 Advantages of vector charts.
Chart information is stored in layers,
Users may customize chart displays to suit the particular needs of their vessels,
The chart data is seamless,
It is possible to zoom in without distorting the charted data,
It is possible to select a safety depth & a safety contour,
Alarms or indications can be given when the own ship is expected to cross safety contour or to enter a specified area.
29. Give 5 Disadvantages of Vector charts?
€¢ Vector charts are technically far more complex than raster charts
€¢ Vector charts take longer and cost more to produce than raster charts
€¢ Significant worldwide coverage will not be provided by official vector charts for many years
€¢ Training in the use of vector charts is likely to be longer and more costly than for raster charts
€¢ It is significantly more difficult to ensure the quality and integrity of the displayed vector data.
30. Give 5 Advantages of Raster charts?
Raster charts are simpler & easier to produce & update than official IHO compliant vector charts
It is much easier to ensure the quality & integrity of the displayed data
They cost less to produce
Official produced raster charts are widely available. For example, ARCS can now provide worldwide coverage
Information from other nautical publications may be displayed in the same raster format.
31. Give 5 Disadvantages of Raster charts.
The display cannot be customized
When raster charts are overlaid with other information
The display may appear cluttered,
Raster charts cannot directly provide alarms or indications to show that own ship is expected to cross a safety contour or to enter a specified area
Raster charts cannot be interrogated without some form of additional database with a common reference system Raster charts cannot be sensibly rotated to head-up or other orientations.
32. What are the ways to avoid over-reliance on ECDIS? (4 points)
Avoid over-reliance on ECDIS for monitoring the route. Correlation of visual, radar, echo sounder, and electronic navigation information is critical to maintaining good situational awareness, especially on a coastal passage in a traffic separation scheme
