Geodesy Proof Of The Flat Earth Deception

This website exposes the flat earth deception and proves that the earth is globe shaped.

Geodesy is the science of accurately measuring and understanding three fundamental properties of the Earth: its geometric shape, its orientation in space, and its gravity field— as well as the changes of these properties with time.

How does your airline pilot know which direction to head when he’s over the ocean with no landmarks? How do we know the exact boundaries between parcels of land and between states and countries?

These are questions we answer with geodesy (sometimes known as Geodetics Engineering): the science of how we characterize the shape and size of the earth.

These surveyors have painstakingly taken measurements from point to point, and using geometry and triangulation, have determined the size of continents, and the shape of the earth.

Geodetic surveying reveals that the angles of the measured triangle exceed 180 degrees, proving that the Earth is curved.  This is called ‘spherical excess’. 

If the Earth was flat, the angles would add up to 180 degrees.

One of the biggest perspective problems is that flat earthers are applying the 8″ per mile squared earth curvature formula to wrong line.

8 inch per mile formula for curved globe earth

One of the biggest perspective problems is that flat earthers are applying the 8" per mile earth curvature formula to wrong line.

Let’s apply this to a picture to see the difference between the level line and the horizon line.

Flat earthers are looking out to the vanishing Horizon Line which is about 3 miles out, and using that line to apply the formula, which is wrong. Obviously the perspective is exaggerated by the small globe in the image below, but the point is the same.

The curvature formula applies to the Astronomical horizon, which is the line created by looking straight out.  In the above image it points out to the sky.

The flat earth curvature formula is being applied to the wrong line.

As long as there have been maps, cartographers have grappled with the impossibility of portraying the globe earth in two dimensions.

To solve this problem mapmakers have created hundreds of map projections, mathematical methods for drawing the round earth on a flat surface.

Yet of the hundreds of existing projections, and the infinite number that are theoretically possible, none is perfectly accurate.

  1. It’s quiet upsetting, I came here desperately hoping to debunk the flat earthers (one who is my mum) using the Sword – Bible, but instead I just see sharp teeth which goes against James 4:11-12.

    The more I see of this type of sharp teeth, the more I am beginning to wonder! At least they use the Bible, but no where in which I turn can I spur them with the Word. NONE.

    From my observations I see two parties: one party uses a sword, the other uses sharp teeth and appear in packs. I now have to loose from my soul the vulgar that my eyes just read which is the last place I thought to see such language.

    Such a shame, onlookers just see Christians causing discord with each other rather than love each other. Such a shame. I now have to face my mum with no Bible proof.

  2. No The 8 inches per mile squared is supposed to be measuring the drop of the actual earth, starting under Your Feet and going in all directions from there, You can’t measure the drop value of fresh air…. My God ??????????
    Ye don’t even have a Geometric Horizon for Christ’s sake its Over….
    More Globe Nonsense based on Pre- Assumption and Begging the Question Fallacy….

  3. To those who believe Earth is flat… I would like to prove to you that you actually do believe in a globe earth. Please honestly answer the following questions:
    I live in Texas, so, I will begin with that example. I have an old fold-up map I used to use to drive around Texas (before the internet.) I also have a globe in my office.
    Can we agree that the SHAPE of Texas is accurate? If your answer is no, or I don’t know, then please STOP HERE. There is no reason for you to continue this thought experiment.
    Can we agree that the shape of Texas on a fold-up map looks identical on a globe?
    Can we agree that the SHAPE of the U.S. also looks identical on a fold-up map and a globe?
    Can we agree that Australia also looks identical on a fold-up map and a globe?
    Can we agree that Australia is about the same size as the U.S.?
    EXCEPT for Antarctica, can we agree that the size and shape of all the continents appear virtually identical on both fold-up maps and a globe?
    If we agree on the SHAPES of the continents, can we agree on their distances from each other; can we agree that London is approx. 3400 miles from New York City?
    Can we agree that Hawaii is about 2500 miles from Los Angeles?
    Can we agree that Auckland is about 1300 miles from Sydney?
    Can we agree that Perth is about 5100 miles from Johannesburg?

    If you answered yes to all these questions, then you absolutely do agree with the shapes and distances represented on a globe. If you deny the layout of a globe, then you are denying the real shapes and real distances. The reason there is no accurate map of the flat earth is because IT IS IMPOSSIBLE to represent both shapes and distances on a flat surface. We don’t need science or religion to help us understand this.


  4. I’ve M.D. in art and I do that for living. I’ve study drawings and perspective for over 16 years and apply the law of perspective and vanishing Horizon Line in anything I do in my job. Are you mean to tell me that what I learned and do is wrong ?

    • No, I’m not telling you that what you learned about perspective is wrong. You of all people should understand perspective and how objects grow smaller, the further away they are from you. But that is not what we see with the sun and moon. They rise up at full size, instead of appearing as a small dot which grows bigger. They set at full size, disappearing below the horizon line. If the Earth were flat, they would grow smaller until they disappear as a small dot, and they would always stay above the horizon line.

        • What doesn’t work properly on the flat earth model is the sun rising at full size from below the horizon, staying the same size all the way across the sky, and then setting at full size below the horizon. That is not possible with a sun that is closer, as the sun would appear as a small dot above the eastern horizon, grow dynamically in size as it moves overhead and then would shrink down to a small dot above the western horizon.

  5. Yes, you’re absolutely right. I’m no scientist whatsoever but I can use my brain to at least reason in the following way:
    All those flat-earthers who might have ventured here to read this website, how come with your assumption of the earth being flat you actually have to say that ALL of the scientific research done over the past several hundreds of years is all false?
    -You’d have to say that what people can observe via telescopes is false.
    -That all the astronauts are telling lies!
    -All the pilots that are flying around the world have conspired to tell us something different from what they actually experience when they fly to their destinations.
    -And all of the ships captains are also sticking their heads together to tell us outright lies.
    -And what is more, all of this would’ve had to be done collectively over centuries.

    You see clearly from this line of reasoning that your theory falls down FLAT.

    • mate… astronauts. theres this thing called money, everyone is bought and paid or they wouldn’t be there. keep believing the moon landing.

  6. EXCELLANT explanation of geodesy that affirms the heliocentric planetary physics model of the earth, celestial motion, gravity, size and relative relations of the solar system’s major bodies.

    Flatearther questions:
    So, what is the purpose for trying to discredit and overthrow a theory that does every single thing that a theory is needed for and does everything its supposed to? Not only does the heliocentric planetary physics model reconcile EVERY disparate observation, curiousity, previously unresolved issue, apparent paradoxes and miscellaneous data from close observation, painstaking detailed record-keeping and correlating, acquired over not just hundreds but over thousands of years, but one that is the basis for explaining the workings of the earth and planets, suns and moons to an unprecedented, incredibly fine extent — yielding predictions of solar and lunar cycles, phases, and planetary positions re: transits, rising, setting, etc to within arc-seconds over 100 years in advance. And folks like you grumble over the inanity of a one-in-several hundredths-thousands slope you can’t see by eye, or measure with a yardstick? If you’re not kidding yourself or taking the piss, then you’re either volunteering to be used as somebody’s fool — or you have a serious modern mental illness that has compromised your reason, logic and critical thinking skills.

    Again: WHY try to throw-away one of the most successful, practical, effective, useful, consistent and well-understood theories ever devised, that accounts for and/or is verified in everything from astrophysics, nuclear physics, celestial and orbital mechanics, astronomy, topographical navigation, orbital, ordinary and circumpolar-navigation, gravity and atomic forces, planetary motion, telemetry, Keplers Conservation of angular and mass-momentum, geolocation, cosmology, radio and optical physics, calculus, global telecommunications, meteorology, volcanism, earth science, geology, quantum physics, oceanography, plate techtonics, ballistics, mineralogy, to mining science, geography, seafaring and merchant marine science, space exploration and -medicine, archeology and anthropology, ancient and modern history, cartography and another score or more of modern earth-solar science fields? Your fantasist, fatalist obsession makes abso-fucking-lutely no sense as anything but compulsive delusionary indulgence. You don’t even have the basic common sense to intuit let alone realize what a gullible and naive babe-in-the-woods you are to imagine such a monumental cover-up disinfo conspiracy is even possible — or WHAT ever for?

    People who think planetary physics can be ‘disproven’ with digression, obfuscation and mock-clever sophistry, or that it ‘relies’ on anything NASA officially says or photographs and maps they produce, or the claims of a US corporate=government/military conglomerate, the perjured testimony and lies of astronauts and technicians, etc, simply do not understand the systematic, comprehensive methodology of science, what it is and how it keeps the entire body of modern scientific knowledge on-focus, relevant, consistent, constantly verified and experimentally validated. And IF they could, or should, find that planetary physics is suddenly a broken model that no-longer provides repeatable, verified factual predictions, accurate calculations and dependable results, WHAT in the world would it be replaced with? There ISN’T anything else!

    BUT that’s not even ‘the point’. There IS no apparant irreconciliable real-world problems, conundrums, false-results, flawed calculations and errors derived from the heliocentric model of planetary motions and dispositions. Instead of improving the model with finer detailed observations, experiments and disproofs that test predictions leading to more refinements or a more-encompassing understanding of mass/momentum, celestial mechanics and force of gravity, the Flatearther’s sole game is a complete and total trashing of the entire model based on specious ‘objections’ and off-the-wall bitter-end argumentums that drive Sophistry as far-off into the deep-end of contrived lost-cause territory as it will take them — where they get-off and continue thru the boggy wasteland wilderness on foot, wielding their machete’s with great alacritity and passion if not deft skill to cut the root-snags, leafy hanging foilage, towering weed-forests and whipsawn-cactuses of doubt and established knowledge that impede their journey towards the mecca of their idealized end-state be-all Knowingness nirvanna where their convictions are validated.

    From China to Vietnam, India and Greece to Indonesia, Turkey and Russia, Germany and USA, Canada, Spain, England, Nations of Africa and South America, the only theory that everybody uses and relies on to explain eveything from gravity and sunrises, star-fields and planetary motion, the waxing and waning of seasons and annual cycles of planting and harvests and moon-pases, is the one the Flatearthers want to get rid of because they think everything they think they know, what they’ve been ‘told’ and taught, is a damn lie. Yeah, that makes sense … NOT! They want to believe the world is a huge static flatland Truman Show matrix Stage, eh? And this group of Flatearthers is apparently immune to irony and self-reflection, whose credibility is strained and squandered beyond breaking by the utter inanity of their disputing and denying the existence of orbits and spacecraft, rockets and satellites — despite their relying on that very technology everytime they access the internet to make their silly scientifically-illiterate disproof arguments. You just can’t make this shit up! ~ ; )
