What are the limitations of the Mercator projection
Limitations. The poles cannot be represented on the Mercator projection. All meridians can be projected, but the upper and lower limits of latitude are at 89° north and 89° south. When used for web mapping with EPSG:3857, the upper and lower limits of latitude are at approximately 85°03'04.0636" north and south.
Where does most of the distortion occur on a Mercator projection Why
Although the linear scale is equal in all directions around any point, thus preserving the angles and the shapes of small objects, the Mercator projection distorts the size of objects as the latitude increases from the equator to the poles, where the scale becomes infinite.
Why is the Mercator projection not a perfect map
In the tropics the cylinder is close to the Earth's surface, and an accurate representation results. At high latitudes the cylinder departs indefinitely far from the Earth: distances and areas are grossly distorted. As a result, Mercator's map becomes useless at high latitudes due to the excessive distortion.
How and why is the Mercator projection of the world inaccurate
Conformal projections preserve angles around all locations. Because the linear scale of a Mercator map increases with latitude, it distorts the size of geographical objects far from the equator and conveys a distorted perception of the overall geometry of the planet.
Where is a Mercator map accurate and distorted
As it is a cylindrical projection, regions that touch the equator are the most accurately portrayed in regard to relative size, while areas that are closer to the polar regions are more distorted. For example, this makes Greenland appear much larger compared to other land masses.
What is lost by using the Mercator projection
The Mercator projection doesn't allow the charting of angles. The projection delivers a very distorted area. One example is that Greenland is shown to have the same size as Africa but in reality, Africa is much bigger than Greenland.
Which map projection is the most accurate
AuthaGraph The AuthaGraphy projection
AuthaGraph. The AuthaGraphy projection was created by Japanese architect Hajime Narukawa in 1999. It is considered the most accurate projection in the mapping world for its way of showing relative areas of landmasses and oceans with very little distortion of shapes.
What is accurate about Mercator
At closer zoom levels, users are typically using maps for things like navigation, which the Mercator projection was designed for. The exact angles of roads and borders are preserved in this projection.
Why do people still use the Mercator projection
It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator.
What is more accurate than Mercator projection
Authagraph Projection – Accurate True Size Map
This map represents the relative size of countries and land area much more accurately than Mercator maps. It also reduces shape distortion and avoids dead ends. This allows us to visualize the world by expanding the map in any direction.
What maps are more accurate than Mercator
AuthaGraph. This is hands-down the most accurate map projection in existence. In fact, AuthaGraph World Map is so proportionally perfect, it magically folds it into a three-dimensional globe.
Which map is most accurate
The AuthaGraph
View the world in correct proportions with this map. You may not know this, but the world map you've been using since, say, kindergarten, is pretty wonky. The Mercator projection map is the most popular, but it is also riddled with inaccuracies.
Is Mercator good for navigation
The Mercator projection is widely used for navigation charts, because any straight line on a Mercator projection map is a line of constant true bearing that enables a navigator to plot a straight-line course.
Why is the Mercator the best
One of the most famous map projections is the Mercator, created by a Flemish cartographer and geographer, Geradus Mercator in 1569. It became the standard map projection for nautical purposes because of its ability to represent lines of constant true direction.
Is there a 100% accurate map
While no map is perfect – they are two-dimensional after all – there have been other attempts to change our perceptions, and decolonise the often-used Mercator Projection. The Gall-Peters projection, which works to correct the Mercator colonial distortions, shows a more accurate image of the world.
Is Google map 100% accurate
Anyone who's ever missed a turn because Google Maps lagged knows that mobile GPS isn't always 100% accurate. Generally, smartphone and tablet accuracy can range anywhere from 16-100 feet (5-30 meters), but this varies by model. A typical resolution for most devices is ~16 feet under open sky.
Why not to use Web Mercator
Similar to the Mercator projection, areas stretch out towards the poles. This means you should not use this projection to display the poles. Due to the apparent distortions, the Web Mercator projection is also not appropriate for any spatial analysis or area calculations.
Is the Mercator the most accurate
The Mercator map, though created with the best intentions, is very distorted. The map does not follow the same scale throughout and as a result, the sizes of various nations are either too large or small. Uma delves more into the Map Projection Bias and its withstanding implications.
How accurate is a 1 10000 map
If you mark up a feature such as a site boundary with a 1mm thickness line on a 1:10,000 map, then you will be accurate to +/-10 metres, marking the same site on a 1:250,000 map will be accurate to +/- 250 metres.

Does Google Maps still use Mercator
Google Maps use a Spherical Normal (equatorial) variant of the Mercator projection for its map images. The Mercator map was developed in 1569 by Gerardus Mercator as a navigation tool based on a rectangular grid with parallel lines of latitude and longitude.
Why do we still use Mercator
It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator.
Are any maps 100 accurate
The short answer: absolutely not. Thanks to the varying distances between latitude lines away from the equator, the map pretty severely distorts surrounding landmasses.
Is the world map 100% accurate
Though designed with the best of intentions — to provide a detailed and coherent projection of Earth — flat maps are far from accurate; some areas look far bigger than they really are, others appear much smaller, and distances between various land masses are misrepresented.
