Sailings

Sailing is a method of solving the various problems involving course, distance, difference of latitude, difference of longitude, and departure.

The app plots on a Google map the route between a departure and a destination point, using the following sailings:

- Rhumb line (loxodromic).

- Great Circle (orthodromic).

And calculates:

- Course & distance.

- Waypoints of the great circle route.

- Save between Rhumb line and Great Circle route.

- Nodes and vertices of the Great Circle.

It also plots the entire Great Circle.

OPERATION

1 - Long click 1: adds the departure point

2 - Long click 2: adds the destination point and plots RL & GC

3 - Tap the Mark to see the information

4- [Output]

- GC course C and distance D

- Save between RL & GC

- Waypoints of the GC route

- Vertices and nodes of the GC
