For further understanding of this subject, here is a noteworthy professional on the subject of latitude and longitude.

The Principle of the Sextant. The optical principle used in a sextant is this: given that a ray of light is reflected from two mirrors in succession, then the angle between the first and last direction of the ray is twice the angle between the mirrors.

Marine Navigational Equipment: The Sextant

Many of us have seen photographs of seamen using a marine sextant. What exactly is that navigator measuring? Learn how a sextant works to help marine navigators find their position.

Sextant Navigation - The Altitudes
sextant

In marine navigation, when a navigator measures the altitude of a celestial body with a marine sextant he has to measure the altitude as an angle of the body above the visible horizon.

The altitude thus obtained has to be corrected for instrument and other errors before calculations can be made.

The Marine Sextant

The sextant derives its name from the extent of its limb which is the sixth part of a circle, or 60 degrees. The marine sextant is a double reflection instrument, used for measuring angles in then same plane. The arc is graduated into degrees from right to left from 0 to 120 (sometimes a little more). However the limb is only 1/6th of a circle due to the instrument double Reflecting.

To the right of 0 degrees on the arc is graduated 5 degrees. This arc of excess is called ‘Off the arc’, and the arc to the left of the zero is termed ‘On the arc’.

The sextant can be used to measure angles in vertical, horizontal or oblique PLANES.

Now that we have well established that a sextant is designed to work with parallel lines, reflecting mirrors, line of sight and degrees of an arc, (not the globe earth,) that they measure planes, and that the measurements are recorded on a grid map, I think its safe to say, along with gyros, astrolabes, compasses, bubble levels etc, the earth measured by such things is proven not a globe.

Neil,
You should watch the following video which explains how the stars work in the flat earth.

are you interested though?

There isn't much point having a conversation with you, because you ignore anything that you don't like. You still have failed to answer where the missing hundreds of feet came from way back a few months ago. This seeing of objects is THE proof par excellence of the flat earth, and you have not answered it.

BTW what is my remarking on your unhappiness indicative of?

But to go back to navigation, I'm at a loss as to why anything you show proves curvature on the earth. Can you explain? Have you studied the flat earth maps? Have you tried to conceive how it would work on a flat earth model?

Quote from: noOneImportant

Stop being needlessly pedantic and condescending, and make an argument. I agree with you and I still find you almost as infuriating as the deluded people in this thread.

I just thumbed-up NoOne's post about Neil - unbelievable...haha.
