Splitscreen-and-Menu-M.jpg

Mobile apps needs a split screen:

Chart at left side
Navigation data at right side

For an optimal workflow, we need a specific userfriendly "look and feel" for chart, nav data and menu.

Chart

Split screen left side, 80%

Navigation data

Split screen right side, 20%

Data from NMEA ship navigation by WLAN
(alternatively by internal GPS)

Ship position

Ship-cursor

A ship-cursor shows the position in the center of the chart.
When the ship is not in motion, the cursor switch to a standard-cursor (or to another colour).
Ship-cursor directed to the course.
Dashed line marks the stearing yourse (optional switch off/on).

Cursor

Rubberband-Cursor

Rubber band cursor from ship position
with crosshair-cursor
display of course and distance from ship position to cursor,
and coordinate of cursor (copy of coordinate to clipboard).

Measuring tool

1. set a starting point
2. move the crosshair-cursor (works like rubberband-cursor)
setting a target point keeps the line on the chart
