# What is Gall Peters projection used for?

## What is Gall Peters projection used for?

Maps not only represent the world, they shape the way we see it. The revolutionary Peters Projection map presents countries in their true proportion to one another: it has been adopted by the UN, aid agencies, schools and businesses around the world.

### What are the 3 types of cylindrical projection?

• Mercator Projection. The legendary Flemish cartographer Gerardus Mercator created the Mercator projection by mathematically projecting a vertically oriented cylinder tangent to the Equator.
• Transverse Mercator Projection.
• Miller Projection.

#### What is galls projection explain it?

The Gall–Peters projection is a rectangular, equal-area map projection. Like all equal-area projections, it distorts most shapes. It is a cylindrical equal-area projection with latitudes 45° north and south as the regions on the map that have no distortion.

What is the difference between Mercator and Gall-Peters projection?

In addition, Mercator only distorts longitudinal distances (except very close to the poles), whereas Peters screws up the scale almost everywhere for both longitude and latitude. This is why Mercator beats out Peters in the world of cartography, and why Google Maps uses a modified Mercator projection.

Advantages: On Peters’s projection, […], areas of equal size on the globe are also equally sized on the map. Disadvantages: Peters’s chosen projection suffers extreme distortion in the polar regions, as any cylindrical projection must, and its distortion along the equator is considerable.

## Why is it called a stereographic projection?

The stereographic projection is a mapping that projects the sphere onto a plane. This projection is defined on the whole sphere, except at the projection point.

### What is Gall-Peters and Mercator?

This month, public schools in Boston district decided to switch from the most conventional world map (depicted below), known as the Mercator’s projection with the one depicted on the top, known as the Gall-Peters projection, which depicts continents and nations by their actual size, as proportionate to one another.

#### What are the strengths and weaknesses of Peters map?

Which type of map projection that uses a cylinder as the projection surface?

These surfaces are cylindrical (e.g., Mercator), conic (e.g., Albers), and plane (e.g., stereographic). Many mathematical projections, however, do not neatly fit into any of these three conceptual projection methods.
