Which projection casts rays from a point on the surface of the globe to a cylinder?

Which type of projection is also called cylindrical projection?

Mercator projection

The familiar Mercator projection (q.v.) is a cylindrical projection.

What is cylindrical projection used for?

Cylindrical projections are commonly used for world maps, regions bordering the equator, and regions that are predominantly north-south in extent.
 

What is an example of a cylindrical projection?

Cylindrical Projection Examples



When you place a cylinder around a globe and unravel it, you get the cylindrical projection. Strangely enough, you see cylindrical projections like the Mercator and Miller for wall maps even though it inflates the Arctic.
 

How is a cylindrical map projection made?

Cylindrical projections. Conceptually, cylindrical projections are created by wrapping a cylinder around a globe and projecting light through the globe onto the cylinder. Cylindrical projections represent meridians as straight, evenly-spaced, vertical lines and parallels as straight horizontal lines.

Is Mercator projection cylindrical?

Description. Mercator is a conformal cylindrical map projection that was originally created to display accurate compass bearings for sea travel. An additional feature of this projection is that all local shapes are accurate and correctly defined at infinitesimal scale.

Is Mercator cylindrical?

Mercator projection, type of map projection introduced in 1569 by Gerardus Mercator. It is often described as a cylindrical projection, but it must be derived mathematically.

What is the most common cylindrical projection?

The Mercator projection

The Mercator projection is one of the most common cylindrical projections, and the equator is usually its line of tangency. Meridians are geometrically projected onto the cylindrical surface, and parallels are mathematically projected.

Why do we use the Mercator projection?

This map, with its Mercator projection, was designed to help sailors navigate around the globe. They could use latitude and longitude lines to plot a straight route. Mercator’s projection laid out the globe as a flattened version of a cylinder. All the latitude and longitude lines intersected at 90-degree angles.
 

What is conic projection used for?

Conic projections are used for midlatitude zones that have an east–west orientation. Somewhat more complex Conic projections contact the global surface at two locations. These projections are called Secant projections and are defined by two standard parallels.

What is the most common cylindrical projection?

The Mercator projection

The Mercator projection is one of the most common cylindrical projections, and the equator is usually its line of tangency. Meridians are geometrically projected onto the cylindrical surface, and parallels are mathematically projected.

What is another name for oblique projection?

Oblique (or parallel) projection is simply a generalization of orthographic projection—the projection is parallel, but the plane need not be perpendicular to the projection “rays.” Again, the projection plane M is defined by a point Q on it and a normal vector û, but since û no longer also defines the direction of

What is another name for orthographic projection?

An orthographic projection is a way of representing a 3D object by using several 2D views of the object. Orthographic drawings are also known as multiviews. The most commonly used views are top, front, and right side.
