Flat Map in Google Map

Then use Google Earth.

Then use Google Earth.

They are similar in principle that is using 2D picture and make it like 3D perspective. I give you a link for example
http://lib.ivank.net/?p=demos&d=pseudo3D

if you draw a rectangle on europe and connect the four corners straight and diagonally, you see that the lengths are equal to the lengths in a straight rectangle. however, the lines on google maps are represented as curved. this is proof that google map is simulated as round by using flat dimensions. but they don't do it in the south. Because google map is a complete BS in the southern hemiplane.

Who has measured flat dimensions?

Still waiting for you to give us details of satellite tv transmitters. Without them it shows the earth is not flat.

If there is satellite that gathered data from every point on earth surface then why google map application using 2D map and make it like 3D perspective. It can be proven that impossible we projected every point in a sphere to 2D map.

• My screen, presumably your screen and all maps are only 2D.
  
  
• Contrary to your claim: It is possible to project every point in a sphere to 2D map and the resultant image is called a "projection of the Globe".
  
  All of these projections contain distortion of some form or other.
  Quote from: Dean M Howell

  What four things do map projections distort?
  There are four basic characteristics of a map that are distorted to some degree, depending on the map projection used. These characteristics include distance, direction, shape, and area.

  And this discusses various projections: Which is the best map projection?
  
  Here are four projections of the whole Globe each with their own advantages and disadvantages:
  

  North Polar Azimuthal Equidistant

  "Bi-Polar" Azimuthal Equidistant

  The Robinson Projection focusing more on the ‘look’ of the map than precise measurement of places.

Wait, when did you do this? How big is it? Where can I see this rectangle? I'm sure it would have been in the news.

We've found the diagonal as 1297,46 kms. This is flat diagonal if the distances were flat then would be. Lets verify:

mathematical error limit.

1) When we draw the cities in the map on a plain paper, the resulting diagonels and areas are close to the value to be calculated globally

in short, the above calculations show that the measurements will be compatible if the european map is accepted as flat.

in other words, the distances measured above are the values ​​taken from the flat world map.

No, you found that. I find it as 1925.832 km. (This is because you used the side length of 667.18 km instead of the height of 664.0125 km).
That is a difference of 0.87 km.
That is well outside the uncertainty, as the measurements are to 0.01 km.
That means theses values are different, not the same.

Thanks for the correction. it is important to note that different calculation* types can result in different results. also we do calculate on google maps completely  a fraud map, it's normal to have so much error. The important point here is that the  error limit is below 0.5% which mathematical error limit. Inother say, If you make a mistake of 5 per thousand when you make a natural measurement means that you did not make mistakes. Hence it proves google uses flat earth distances.

Nope. Do not make word salad. Supporting something and using something without paying its copyright is different things. Mercador projection is using flat map datas without paying and supporting the spheres. Mercador should to shame on itself.

You can do it by yourself. We don't expect them to share this information because the media are already ruled by evil forces. Now let's make an example online if you want.

I try to stay in Europe as much as possible. The first point somwehere in UK.

First point Coordinates: (51,0)



The second point (51,15)



Distance (51,0) to (51,15) = 1.047,84 kms.

The third point (45,15)



Distance (51,15) to (45,15) = 1.715,02-1.047,84= 667,18kms.

The fourth point (45,0)



Distance (45,15) to (45,0) = 2.892,73 - 1.715,02 = 1.177,71kms.

The area sum:



distance (45,0) to (51,0)= 3.559,90 - 2.892,73 = 667,17 kms.

Area from google: 741.460,69 km²

Lets draw the distances on a flat paper:



We've found the diagonal as 1295,83 kms. This is flat diagonal if the distances were flat then would be. Lets verify:



Same distance in map is; 1296,70kms.

Total mistake: 0,87 kms.

mistake proportionally: 0,87/1296,7= 0,0007 = 0,07 %

quadratic error for area calculations: 0,07x2 = 0,14%

Area calculated:

(1177,71+1047,84) x 664,01 /2 = 738.893, 73 km²

areal mistake: (741.460,69 - 738.893,73) / 741.460,69 = 0,003 = 0,3 % < 0,5% mathematical error limit.

Results:

1) When we draw the cities in the map on a plain paper, the resulting diagonels and areas are close to the value to be calculated globally and the resulting error remains within the mathematical error limit.

2) field value written on the map is 2 times more than the error in the diagonal value read. in other words, the field value on the map is a fabricated, it does not reflect the truth.

in short, the above calculations show that the measurements will be compatible if the european map is accepted as flat.

in other words, the distances measured above are the values ​​taken from the flat world map. The sphere representation consists of only projection.

Incorrect. How a Mercator Projection is created from a globe which shows why land masses closer to the poles become distorted:

Quote from: Stash on July 08, 2019, 01:35:11 PM

Incorrect. How a Mercator Projection is created from a globe which shows why land masses closer to the poles become distorted:

I dislike that as it hides how the projection is actually made.
I prefer this:

To make the projection you encase Earth in a cylinder and then project from the centre of Earth to that cylinder.
Whatever point on the surface you pass through gets projected to the corresponding point on the cylinder.
Typically you also truncate it as otherwise you would need an infinitely long cylinder.

Then this cylinder is cut open and laid flat.

Ok, I did it:

The (45,0), (45,15), (51,15), (51,0) really has the measures:
a = 1047.84 km
b = 1177.71 km
c = 667.17 km
With diagonals of 1296.70 km

If we find chords of those arc distances we will have:
a = 1046.66
b = 1176.03
c = 666.86

Diagonal will be SQRT(ab + c²) = 1294.45

The corresponding arc for that chord is 1296.69.

Our error here is (1296.69 - 1296.70) / 1296.70 = -0.000007711 = -0.00077%.
Input values were rounded to two decimals and that produced the error of 0.01.

We can say that Google Maps uses arcs of the great circles to show distances.

EDIT: Google also uses more than just two decimals.

Especially it is almost impossible to do the same calculation in China, Russia, South America or Australia. at least in theory. we need to try.

I do not think it will remain within the limits of error.

No, it is just as possible.
If you pick a small area, the error is small.
What stops you is if you pick a much larger area. Then you get much larger errors.

It already isn't.
The limit is roughly 0.01 km. The error is much larger than that.
