6. Indications and alarms can be given when a hazardous situation, such
as crossing a safety contour, occurs.
7. Objects may be shown using different symbols to those used on paper
or raster charts.
8. Chart data may be shared with other equipment such as radar and
ARPA.
9. Unless data content is the same, less memory is required to store
data compared to a raster chart.

Disadvantages of the vector chart can be summarized as follows.
1. They are technically far more complex than raster charts.
2. They are more costly and take longer to produce.
3. Worldwide coverage is unlikely to be achieved for many years, if ever.
4. It is more difficult to ensure the quality and integrity of the displayed
vector data.
5. Training in the use of vector charts is likely to be more time consuming
and costly compared to that needed for raster charts.
