leotruther has shown an obvious issue with my calculation of Latitude.
This is because I have been going about the calculation in an indirect manner and without completing the final step.

Let me explain.

Mapping the Earth - Page 3 Tangen13

For the indirect calculation  of Latitude, I have been using the angle Mapping the Earth - Page 3 Theta11.

This is okay if I complete the calculation by subtracting Mapping the Earth - Page 3 Theta11 from 90 degrees to get the value for the angle γ (gamma) .
See the following:

Mapping the Earth - Page 3 Tangen14

γ (gamma) = 90 minus Mapping the Earth - Page 3 Theta11

which equals the latitude plus or minus the declination of the Sun at your location

So, in leotruther's calculation of Latitude, he arrived at: 66° 52' 47.48" South Latitude

Since the calculation is based on the Indirect method I laid out, to complete the calculation for Latitude we will subtract  66° 52' 47.48" from 90 degrees to obtain the value of angle γ gamma.

90 minus 66° 52' 47.48" =  23° 07' 12.52" South Latitude.  So, in leotruther's case, he must live very close to the Tropic of Capricorn!!  Any signage for the Tropic of Capricorn in your neighborhood?

Note:  The larger degree of angle Mapping the Earth - Page 3 Theta11 puts one closer to the Equator.  I did not see this obvious issue as I reside very near to the 45th degree North latitude!

The Indirect Method of Finding Latitude has additions and subtractions whereas the Direct Method which I will describe next will simply reverse those subtractions and additions since we will be dealing with the angle of most consequence -- γ (gamma)

RedorBlue,
Absolutely a fantastic way to CONFIRM one's True North setting. I am thinking of ways to construct a mechanism that will sit on the True North line and project up AT NIGHT so that one can view the trajectory towards the North Star.

Safesteef,  k4t , etal

Let me know if you are setting up your own apparatus for this mapping project.

If you or ANYONE does not want to perform their own calculations, I will be happy to do that on this forum if you give me the following data:

1.  The current Date.
2.  The number of hours you are West or East of the Universal Meridian at Greenwich, England based on the Gleason map
3.  The height of your Post (P)
4.  The length of the line TN, which is the True North line found by discovering the direction of the meridian above your head.  Remember, this is the line that is the shortest distance between the Post (P) and the arc described by the Sun's progress across your surface.
5. The current local time that the Sun crossed the local meridian at your location.  This will normally happen on Day Two.

This is how simple it is.

Find Latitude Version 3.0 -- The Direct Method

This is the most straightforward method of finding Latitude using:
-- the Height of the Post
-- the length of the line TN
-- the current declination of the Sun north/south of the equator on the current day

Declination Table
Mapping the Earth - Page 3 Sundec11


Mapping the Earth - Page 3 Righta10

First, the angle Gamma (γ) is calculated by taking the arctangent of the Length of line TN divided by the Height of Post (P).

If one is north of the equator and the declination of the Sun is north of the equator, we will ADD the declination of the Sun on the current day to the angle γ to arrive at the current Latitude of our location.  Likewise, if one is south of the equator and the declination of the Sun is south of the equator, we will ADD the angle of declination to γ to arrive at the local Latitude.
If one is north of the equator and the declination of the Sun is south of the equator, then we subtract one from the other to arrive at our local Latitude.
And vice-versa.  Subtract if our location is on the opposite side of the equator than the declination of the Sun.

Taking my example from an earlier post:

Height of Post P = 9 and Length of line TN = 4.5.  

4.5 divided by 9 = .5

The angle Gamma (γ) = The Arctangent of .5 =  26.56505118°

The Declination of the Sun on that day (July 18th) was 21 degrees 08 minutes or 21.13333°

As both my Location and the Declination of the Sun are North of the equator, we add the Declination 21.13333° to  Gamma (γ) 26.56505118° to arrive at 47.69838° = 47° 41' 54.17" North Latitude

Another example using leotruther's data with Version 3.0 of Finding Latitude

The data:
Date of calculation = Aug 5th
Sun declination = N 17" 8'

Height of Post = 30 cm
Length of line = 25.4 cm
-------------

The angle gamma (γ) = arctan( 25.4 / 30 ) = 40.25458926°

The Sun's Declination is 17 degrees 8 minutes = 17.13333° North

As leotruther is South of the equator and the Sun's declnation is North of the equator, we will subtract the Declination from the angle gamma (γ)

So, 40.25458926° minus 17.13333° = 23.12128926 = 23° 7' 16.64" South Latitude

Mapping the Earth - Page 3 Empty Re: Mapping the Earth

Post by bdhfe Fri Aug 13, 2021 5:42 am

I would like to make a small digression in order to provide a very practical reason why mapping the Earth from a Flat Earth perspective is very important.

First, here is a handful of experiences, the source of which I used to know (LOL) but at present cannot recall.

35) If the Earth were truly a globe, then every line of latitude south of the equator would have to measure a gradually smaller and smaller circumference the farther South travelled. If, however, the Earth is an extended plane, then every line of latitude south of the equator should measure a gradually larger and larger circumference the farther South travelled. The fact that many captains navigating south of the equator assuming the globular theory have found themselves drastically out of reckoning, moreso the farther South travelled, testifies to the fact that the Earth is not a ball.

36) During Captain James Clark Ross’s voyages around the Antarctic circumference, he often wrote in his journal perplexed at how they routinely found themselves out of accordance with their charts

37) Lieutenant Charles Wilkes commanded a United States Navy exploration expedition to the Antarctic from 1838 to 1842, and in his journals also mentioned being consistently east of his reckoning, sometimes over 20 miles in less than 18 hours.

38) To quote Reverend Thomas Milner, “In the southern hemisphere, navigators to India have often fancied themselves east of the Cape when still west, and have been driven ashore on the African coast, which, according to their reckoning, lay behind them.

39) Practical distance measurements taken from “The Australian Handbook, Almanack, Shippers’ and Importers’ Directory” state that the straight line distance between Sydney and Nelson is 1550 statute miles. Their given difference in longitude is 22 degrees 2’14”. Therefore if 22 degrees 2’14” out of 360 is 1550 miles, the entirety would measure 25,182 miles. This is not only larger than the ball-Earth is said to be at the equator, but a whole 4262 miles greater than it would be at Sydney’s southern latitude on a globe of said proportions.

40) From near Cape Horn, Chile to Port Philip in Melbourne, Australia the distance is 10,500 miles, or 143 degrees of longitude away. Factoring in the remaining degrees to 360 makes for a total distance of 26,430 miles around this particular latitude, which is over 1500 miles wider than Earth is supposed to be at the equator, and many more thousands of miles wider than it is supposed to be at such Southern latitudes.

41) Similar calculations made from the Cape of Good Hope, South Africa to Melbourne, Australia at an average latitude of 35.5 degrees South, have given an approximate figure of over 25,000 miles, which is again equal to or greater than the Earth’s supposed greatest circumference at the equator. Calculations from Sydney, Australia to Wellington, New Zealand at an average of 37.5 degrees South have given an approximate circumference of 25,500 miles, greater still! According to the ball-Earth theory, the circumference of the Earth at 37.5 degrees Southern latitude should be only 19,757 statute miles, almost six thousand miles less than such practical measurements.

42) In the ball-Earth model Antarctica is an ice continent which covers the bottom of the ball from 78 degrees South latitude to 90 and is therefore not more than 12,000 miles in circumference. Many early explorers including Captain Cook and James Clark Ross, however, in attempting Antarctic circumnavigation took 3 to 4 years and clocked 50-60,000 miles around. The British ship Challenger also made an indirect but complete circumnavigation of Antarctica traversing 69,000 miles. This is entirely inconsistent with the ball model.

One other quick example:  An acquaintance of mine who is a submariner in the US Navy became a Flat Earther after experiencing these absurdities in distances in the Southern Seas on board a submarine.

Summarizing, ALL of these examples illustrates a very important point.  The distances calculated by the Greece Ballers for the Southern latitudes are completely absurd.  By compressing the distance between degrees of Longitude on the Globe, the distances become more and more meaningless as one travels further South.  Instead, as we know from the Flat Earth, the distance between degrees of Longitude increase as we traverse South.
Secondly, the failure of the Globe model to accurately provide good bearings in the South, translates to a skewing or EXTORTION (Gleason's own word) of the land masses on Gleason Map since Gleason essentially used the data provided him by the Freemasons at the Royal Observatory in Greenwich, England.

This mapping project will necessarily correct the land mass distortions in Gleason's and provide a very real and geographically correct view of Earth.

Consequently,  once we have a fairly complete map of the world AS IT REALLY IS, we can provide the US Navy, at least, and international airlines as well, a proper and true picture of the land and sea they travel in and over.

The following is from this website:
Distances in Southern Hemisphere

I quote:
Nowadays there is some support from science that in fact the southern part of the “globe” is larger than the northern part and we have Neil De Grass Tyson declaring that the earth is “pear shaped”.

From Wikipedia:
Neil deGrasse Tyson (US: /dəˈɡræs/ or UK: /dəˈɡrɑːs/; born October 5, 1958) is an American astrophysicist, planetary scientist, author, and science communicator. Tyson studied at Harvard University, the University of Texas at Austin, and Columbia University. From 1991 to 1994, he was a postdoctoral research associate at Princeton University. In 1994, he joined the Hayden Planetarium as a staff scientist and the Princeton faculty as a visiting research scientist and lecturer. In 1996, he became director of the planetarium and oversaw its $210 million reconstruction project, which was completed in 2000. Since 1996, he has been the director of the Hayden Planetarium at the Rose Center for Earth and Space in New York City. The center is part of the American Museum of Natural History, where Tyson founded the Department of Astrophysics in 1997 and has been a research associate in the department since 2003.

From interestingengineering.com:
Neil deGrasse Tyson is a highly accomplished astrophysicist, planetary scientist, author, and something of a celebrity science educator to millions of people around the world.

Neil says:  earth is pear shaped

NASA gives us:
Stunning image of Earth, taken by the DSCOVR Satellite
Mapping the Earth - Page 3 Nasaba10

More Greece Ball nonsense provide by individuals and organizations that can't keep their stories straight.
As an aside, using a fish eye lens, I can make the fruit on my pear trees look just that NASA photo!!

Note: the reason Neil says the earth is pear shaped is because of Australia!!  

And this is another good reason to provide the REAL picture of Earth -- to finally help the poor Australian figure out what the country looks like, AND WHERE IT REALLY RESIDES on Earth.  :-)
They can then cast aside the Greece Ball propaganda, and free themselves from the imaginary strain of hanging by their toes!!

And speaking of Australia.....

Sorry, one more side track to illustrate the importance of this project.

In the United States, here are the Time Zones.  The United States is North of the Equator and the lines of  Longitude diverge at one progresses South.
See how the Time Zones follow this:
Mapping the Earth - Page 3 Ustime10

Now, contrast this with Australia.  Australia is in the Southern latitudes, and of course, based on the Globe theory, the lines of Longitude should Converge as one moves South.  However, see this:
Mapping the Earth - Page 3 Aussie10

The opposite is obviously true as there are more time zones in southern Australia than there are in the northern part of the country.

When the time comes, and it is coming, our mapping project will shed the light on what is really going on in the Land NOT down under.

BDH,

How much data will you need before you can start making your first map? Will this take years?

Hi Hauchfer,
Years?  LOL I hope not.

I figure we have most the information we need based on maps already in existence.
Our project will need the fundamentals of Latitude and Longitude to place the continents in their correct orientation and size.
We know, based on experience, that the globe calculations for Latitude and Longitude are incorrect.
The question is:  which ones, and how much are the calcs wrong for any given land mass?

So, the scheme of this exercise/project is to confirm the correctness of some and show the incorrectness of others, since we know that the Earth is Flat and the devils have been distorting it into something unrecognizable.  That distortion is what we want to ERADICATE.

And, depending on how many mappers are involved and where they reside, the project will take that long.
Any given mapper can perform the operation in two days, and if they are into travelling, they can perform the two day operation with their handy dandy travel kit.  [Travel Kit not yet available  Smile  ]

We know there are Flat Earthers on every continent in the world, so the amount of individual effort should be minimal as well.

It is September 1st and I have performed another Latitude test using Finding Latitude Version 3.0.

My numbers are:
TN = 7.563 inches
P = 9.250 inches
Sun's Declination = 8.5 degrees

Angle gamma (γ) = Arctan(TN/P) = 39.269 degrees

My Latitude = 8.5 + 39.269 = 47.769 degree OR 47° 46' 8.4" North Latitude

Comparing this to the Latitude calculated from July 18th -- 47° 41' 54.17" North Latitude

I am within 5 minutes of a degree difference!!

This is a very acceptable margin of error considering my setup uses a wooden table, some cardboard, a standard size ruler, and a No. 2 pencil.

Tomorrow, my Longitude calculation.

Just a suggestion - using a larger pole would reduce any measurement errors.

For Finding  Longitude Version 2.0 on September 3 (I missed the 2nd)

The Sun crossed the Zenith at 12:47:10 pm
I am 7 hours West of Greenwich Meridian
Analemma chart shows that the Sun is about 15 seconds fast to the Zenith today.

Hence my local Longitude comes to
116 ° 50' 59" W Longitude.

My previous Longitude calculation on July 20 gave me
116° 47' 13.2" W Longitude.

Which is about 3.75 minutes difference between the two.

RedorBlue,
I agree, a larger setup i.e. a taller Post (P), will definitely improve accuracy in both Latitude and Longitude.
