Abstract
A nautical chart processing device is provided. The nautical chart processing device includes processing circuitry. The processing circuitry is configured to receive position information indicating position of a pair of base points on an electronic chart, set a movable measurement point on a straight line connecting the pair of base points in real time, calculate, on the electronic chart, a distance between the movable measurement point and at least one base point of the pair of base points, and output position information of the movable measurement point and the calculated distance.
Claims23
A nautical chart processing device, comprising:
- processing circuitry configured to:
- display an electronic chart on a display,
- receive a first and second input to the electronic chart displayed on the display,
- based on the first and second inputs to the electronic chart displayed on the display:
- receive position information indicating a position of each of a pair of base points on the electronic chart, the position of each of the pair of base points respectively corresponding to the first and second input, and
- display, on the electronic chart, the pair of base points and a first straight line connecting the pair of base points,
- receive a third input to the electronic chart displayed on the display,
- based on the third input to the electronic chart displayed on the display:
- set and display a first movable measurement point on the first straight line that is displayed on the electronic chart,
- wherein the first movable measurement point is movable on the first straight line in real time,
- determine and display a first and second changeable distance on the electronic chart between the first movable measurement point and a corresponding first and second base point of the pair of base points, along with a first static distance between the first and second base points,
- receive a fourth input to the electronic chart displayed on the display, the fourth input being a slide of the third input along the first straight line connecting the first and second base points, and
- while sliding the third input, determine and display, in real time, updates to the first and second changeable distances on the electronic chart, along with the first static distance between the first and second base points.
