Measurements of the Earth Prove it cannot be Flat

There have been a number of threads on Geodetic Surveyors and how they "prove the earth is a Globe". So many "shot them down" saying that Geodetic Surveyors did not "prove curvature", possibly not, but as I have stated so often Geodetic Surveyors measured the earth and have done so with increasing accuracy for centuries. The sizes of all countries and the lat/long coordinates of all features have been measured and can readily be ascertained. The most compact source of this information is in maps (some very accurate, others less so) and atlases (often not very accurate, but usually quite close enough).


The following assumes that at a given latitude, a degree of longitude is the same all around the globe.

This seems quite consistent with all evidence^[1] and with what is in "the Wiki" on Finding your Latitude and Longitude.

The following table gives the width of one degree (under the heading "km/deg") at various latitudes in both the northern and southern hemispheres, the circumference of the earth (the distance for 360°) from the map reading at each latitude, the circumference at that latitude based on a spherical earth (yes, I know it's not a perfect sphere!) and the circumference at that latitude based on a Flat Earth Ice Wall Map.

The "Flat Earth Circumference @ Latitude" is based on the 24,900 mile overall diameter of the "known earth" as in the Wiki, The Ice Wall. The circumferences are then simple "pro-rated" as the meridians on the "FE Ice Wall map" are simply radial lines.
The 1887 US survey map and the 1855 Australian map are very high resolution accurate maps, but the Times Atlas is not such a large scale and not as accurate. Also the figures are scaled (quite accurately) from scanned paper maps, so very high accuracy is not expected. Nevertheless most of the circumferences are within 1% of the expected value for the globe (The "Times Atlas" is a bit out at high southern latitudes - not unexpected for a flat map).

These measurements can be repeated anywhere on earth you like. In many cases, if you have a straight E-W stretch of road you can verify the results yourself. No great accuracy is needed, as the differences between a globe and the flat earth are massive!



[1] Any navigator would think it ridiculous to suggest otherwise.

Captain cook clocked the southern circumference at 67,000 miles which is consistent with a flat plane. Also, geodetic surveying has been refuted as a credible source of info. No doubt they used telescopes for centuries and would have quickly seen that there is no curvature with the equation given at 8 inches × distance squared. They would have also quickly noticed that boats don't disappear behind curvature when sailing off into the horizon. Geodetic surveying is also a Masonic created. They lied about the poles and curvature. No curve means no ball

1. Here you go, the voyages of Captain Cook. You'll find he was very confused, and in no way did he trace out any particular latitude by which to determine the circumference of the Earth at that latitude. Nice try though.

2. Source. You can't disprove something by just saying it's been disproven. You kinda need to disprove it first.
3. Obviously you can't discern curvature at a distance of 8 inches. The irregularity of the crust would prevent there from being curvature on so small a scale.
4. They would have quickly noticed that boats disappear behind curvature when sailing off into the horizon. FEers see their own thing, REers see their own thing. This cannot be used to prove either model because both sides believe it proves their own.
5. Again, source? Plus even if the Freemasons invented geodetic surveying that wouldn't mean it's not a reliable source of information. That's like saying a news station that has told lies in the past never tells honest information.

Essentially what you are claiming is that ALL the maps we have been using for navigation and simply finding locations and distances are wrong. You do not have the slightest evidence for this, except that they do not agree with YOUR map. Apart from anything else Frankly I find that a ridiculous situation for a group expecting world wide acceptance.

Captain cook clocked the southern circumference at 67,000 miles which is consistent with a flat plane.

No! The statement that "Captain cook clocked the southern circumference at 67,000 miles" is completely false, but is a lie often touted by Flat Earthers! Cook's whole voyage from England and back to England "lasted three years and eight days covering more than 60,000 miles", NOT just the bit around Antarctica as Flat Earthers falsely claim.

You really should study up on things yourself, instead of believing rubbish on Youtube or wherever you got it from:

The voyage lasted three years and eight days covering more than 60,000 miles. Cook had proved there was no southern continent unless it was at the pole itself.

From: James Cook, 1728-1779

Also, geodetic surveying has been refuted as a credible source of info.

This is utter rubbish! The main task of Geodetic Surveyors is simply the measurement and location feature on the earth. Most of this is in mapping countries and continents. Over the past few centuries essentially all of the earth has been accurately mapped. And the shape does not agree with you "precious map". THAT is why you have to denigrate them, and for no other reason.

So, you really do need good evidence for such a slur of a highly respected profession.

No doubt they used telescopes for centuries and would have quickly seen that there is no curvature with the equation given at 8 inches × distance squared.

You know something I have NEVER seen a convincing of any object that has actually disappeared over the horizon "brought back" by telescope or zoom lens. I have seen ships and buildings hidden numerous times, and the actual amount does vary somewhat due to refraction. If you are interested you could read Refraction, ROHAN Academic Computing.

They would have also quickly noticed that boats don't disappear behind curvature when sailing off into the horizon.

Are you so sure!
But ships certainly get hidden:

Diamond Princess leaving Harbour

Diamond Princess partly over horizon

Diamond Princess well over horizon (framed for overlay)

Diamond Princess original ship overlayed on prev picture

Some people still think they do, and those photos were taken with quite a high zoom!

Geodetic surveying is also a Masonic created.

You do have some sound evidence of this accusation! Do you really believe that the Masons were active in Islamic cultures? Al-Biruni (973 - 1048) is regarded as the father of Geodesy and you will never convince me he was a Mason.

I suppose you are going to claim all these were Free Masons as well!
Pythagoras (570-495BC), Plato (424? -  348?BC) - he like round!, Eratosthenes ( -194BC), Ptolemy (90 -168), Al-Biruni (973 - 1048),
Nicolaus Copernicus (1473 – 1543), Tycho Brahe (1546-1601), Galileo Galilei (1564–1642), Johannes Kepler (1571-1630),
Sir Isaac Newton (1642 - 1727), Henry Cavendish (1731-1810) and Albert Einstein (1879 - 1955).

Those before Nicolaus Copernicus and Tycho Brahe probably believed the earth stationary. The rest certainly believed that the earth rotated on its axis and orbited the sun.

They lied about the poles and curvature. No curve means no ball

Again please give some evidence! Your simply saying it is so is completely useless.

No, you are completely mistaken if you claim there is no South Pole, you do not have the slightest trace of evidence for that silly claim! Your "Ice Wall Map" is so grossly out (as I showed in my original post) that it is honestly completely useless for navigation, distances or the shapes of countries!

If you want to see how far out your map is just look at:
It's just too bad that those that live in the Southern Hemisphere do know a few things about the Southern Hemisphere continents.

I for one KNOW that Australia is NOT the shape shown on that map. We don't have an accurate copy of that map to measure distances, but the shapes of the Southern Hemisphere continents seem the same as on "Gleason's Map", so for the present I will demonstrate what I mean on that. If there is an alternate map I would be glad to use that.

To see what I mean about the E-W distances being grossly stretched on the Gleason's Map just look at these two maps of Australia.  The one on the left is from Gleason's and the one on the right on Google Earth.  I used the Google Earth as a quick way to get the shape right, but the measurement shown are from my Garmin Navigator map. I have checked this numerous times, both with map (surveyed) distances between towns and the car oddometer, which I know  is not more than 1% out (not all cars are that close - maybe Landcruisers are not that bad!).


As you can see the on both the "Ice Wall Map" and the "Gleason's Map" the shape of Australia is grossly distorted, with the East-West distance on the "Ice Wall Map" and "Gleason Map" being 8,700 km compared to a more accurate distance of 3,700 km. The distances on the "Ice Wall Map" and  "Gleason's Map" are estimated by comparing the lengths with the Equator to North Pole taken as 10,000 km.
The North-South distances agree very well, but E-W distances are grossly in error - All the distances have been rounded to the nearest 100 km.

I know the column labelled "Garmin" is correct as I have driven over much of that area (yes all the way from west to east, tnough not ON the 30° Lat). I have personally checked the maps, the car oddo and the "Garmin" (GPS) and all are in good agreement.


If you try to challenge this I will have to come back with all the quite impossible (on the Flat Earth map) air routes we have down here!

We have learnt long ago that any evidence that contradicts Flat Earth Theory is automatically deemed:
A fake,
A pure lie,
A plot by one or more of Masonic, Jesuit, Zionist, Rosicrucian, The Brotherhood, The Illuminati, or all of these somehow working together.
Any photo contrary to you beliefs is deemed Photoshoped. (I'm safe I don't use Photoshop!)

Captain cook clocked the southern circumference at 67,000 miles which is consistent with a flat plane.

Every time I see this different number is given. I found 88500-96500km, which is not consistent with a flat plane. It didn't make any sense even if we assume the distance was covered by a circumnavigation only.

Also, geodetic surveying has been refuted as a credible source of info. No doubt they used telescopes for centuries and would have quickly seen that there is no curvature with the equation given at 8 inches × distance squared.

The equation is not valid. You seem to blindly repeat some FE formula that doesn't work.

They would have also quickly noticed that boats don't disappear behind curvature when sailing off into the horizon.

If the earth was flat. There are multiple examples showing the opposite. People figured that out once they started sailing. Long before geodetics, NASA, USA goverment or any other agency.

Geodetic surveying is also a Masonic created.

Wow, the idiot light came on very quickly in this thread, on the very first reply! 

Your measurements of the actual Earth are accurate, but those surveyed results have been altered. All this means is that your maps are incomplete. There are lands and spaces not accounted for meaning only the elite and those from beyond the ice wall have access to the locations, and the minerals and oil and precious substances therein.

If my measurements are correct, then the earth cannot be flat!

But what evidence do have for claiming that "those surveyed results have been altered"?

Or is this just more stuff coming from the over-fertile imagination of Twiddles?

You do realise that "Triddles said so" does not mean it is true unless you can come up with some corroborating evidence.
That might not be your intention, but you are succeeding admirably. Carry on the great work!
