The batteries don't run out they are lighter and more accurate than GPS and they'll survive WW3. You can also make them yourself.

Yeah, the only similarity between direction in surface navigation and grid angle measurement is that they both involve angles. One standard orientation has nothing to do with the other. Standard map and globe orientation is that North is 0° and points "up" . Angles in mathematics are generally measured with the X axis being 0-180 with 0° to the right, and 90° "up"
It appears that the confusion is that some people were trying to use one standard for something unrelated.
No.
1º GPS can simply be charged with a solar panel, they really aren't super energy hungry.
2º The compass won't tell you where you are, only where you are facing & even that isn't particularly precise since the magnetic north moves quite a lot over the years.
The other points are valid though we aren't on WW3 & I think it'd take me less time to gather the money to buy a compass than to look for the materials for it.
It was indeed what I thought then.
Oh dear, you really don't know anything about navigation do you
Still, if there's ever a thread about physics homework we know who to call, lol

Teach me captain Factabulous. Your sailings around the globe must mean you know what you are talking about.
Well, I did win a statal contest in physics & this parcial I got a 99 score in my physics subject without studying a single hour. Want to know more about me or is that enough for you?
So, to recap ...
0° = North
90° = East
180° = South
270° = West
90° = East
180° = South
270° = West
You just got an F from Floweys physics teacher, but that's OK he can't find the staff room to write it down.
*In Cartography.
Actually, that'd have been an F from all the physics teachers in the highschool.
Yes, that's the point all the people who were right have been persistently making to you.
Well done! I guess you didn't make your own way there
I'm an introvert so I didn't get help from any peers.
Curiously, I mentioned just that in post #15.
Don't sweat it being wrong on the internet isn't a big deal.
I must say I am very impressed by Flowey.
This thread is very surreal, good show everyone, along with the good old days thread, my aching bones have been soothed by laughter tonight.

Thanks for that CMDR
I drew something similar on paper then threw it away after I had learnt it.
Pretty nailed it. It's just basic navigation. Be glad we don't need dividers and parallel rules to chart plot.
I won't admit failure where there is not, read the post. I said that both fields had different standards yet you ignore it.

This is a bearing compass. There's one just like this on my boat. It helps me get around. If Magellan had had one of these, he'd have found the East Indies.

This is a song about Magellan.
And this is a compass rose indicating both magnetic and true north. Mixing the two up will ensure you never get where you want to go.

Don't forget grid North the most tricksy of all the Norths.
Just something that might help...
Latitude
Lines of latitude measure north-south position between the poles. The equator is defined as 0 degrees, the North Pole is 90 degrees north, and the South Pole is 90 degrees south. Lines of latitude are all parallel to each other, thus they are often referred to as parallels.
The memory rhyme I use to help remember that lines of latitude denote north-south distance is:
"Tropical latitudes improve my attitude"
One degree of latitude is
60 nautical miles, 69 statute miles or 111 km.
One minute of latitude is
1 nautical mile, 1.15 statute miles, or 1.85 km.
Longitude
Lines of longitude, or meridians, run between the North and South Poles. They measure east-west position. The prime meridian is assigned the value of 0 degrees, and runs through Greenwich, England. Meridians to the west of the prime meridian are measured in degrees west and likewise those to the east of the prime meridian are measured to by their number of degrees east.
The memory rhyme I use to help remember that lines of longitude denote east-west distance is:
"Lines of LONGitude are all just as
LONG as one another."
With this saying in my mind, I picture all of the longitudinal meridians meeting at the poles, each meridian the same length as the next.
