The cursor and other control devices
The cursor is usually steered by a tracker ball or touch pad in order to:
- Plot WPs and to mark or change them.
- Make measurements on electronic charts. ECDIS requires that the same operations that are performed on paper charts can also be performed on electronic charts, such as reading off courses, measuring distances and plotting fixes using latitude and longitude.
- Gather additional information on a highlighted object.
