336 |
* <h4>Explanation:</h4>
|
337 |
* We get an isosceles triangle with the center of the Earth and the 2
|
338 |
* points on the surface. This triangle can be divided into two rectangle
|
339 |
* triangles. We know two values, the angle of 1 grade, that will be 0.50
|
340 |
* grades in each triangle, and the Earth radius that is the hypotenuse.
|
341 |
* Then we apply trigonometry and get the distance <i>D</i> between both
|
342 |
* points on the Earth surface.</p>
|
343 |
* <p>
|
344 |
* Now we only must invert that value to obtain

* <code>MapContext.CHANGE[8]</code>.</p>
