Does the Mercator projection distort size?

Does the Mercator projection distort size?

The popular Mercator projection distorts the relative size of landmasses, exaggerating the size of land near the poles as compared to areas near the equator.

What does the Mercator projection not distort?

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 Robinson projection a better alternative to the Mercator projection when looking at the earth?

Also, there is less distortion in the Polar regions. Unlike the Mercator projection, the Robinson projection has both the lines of altitude and longitude evenly spaced across the map.

Why is the Web Mercator projection commonly used for online mapping and why does that matter?

The reason Web Mercator was suitable as the basis for early web mapping is that it creates a convenient square shape for the entire world if it is truncated at approximately 85° North and South of the Equator. Wherever you are on the map, up is due north, down is due south and west and east are always left and right.

Which is Web Mercator projection do you use?

Most maps you see on ArcGIS Online, Bing, and Google use the Web Mercator map projection (figure 1). Figure 1. The Web Mercator projection which is commonly used for Web Maps. For the Fan Map: Super Bowl Edition, we decided to try something different and chose the Winkel tripel projection (figure 2).

Which is the best version of Mercator for ArcGIS?

Its variant, the Web Mercator projection, is standard for web maps and online services. The projection is often misused for world maps, wall charts, and thematic mapping on web maps. There are four variants available in ArcGIS: Mercator is also known as Mercator variant B.

Which is Mercator coordinate system does Google use?

The Web Mercator coordinate system is also known as Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator, and Pseudo-Mercator. It is the de facto standard for web maps and online services.

How big is the deviation from the Mercator projection?

The discrepancy is imperceptible at the global scale but causes maps of local areas to deviate slightly from true ellipsoidal Mercator maps at the same scale. This deviation becomes more pronounced further from the equator, and can reach as much as 40 km on the ground.
