What are Mercator maps good for?

What are Mercator maps good for?

Mercator projection, type of map projection introduced in 1569 by Gerardus Mercator. This 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.

What is a Homolosine projection map?

homolosine projection. / (hɒˈmɒləˌsaɪn) / noun. a map projection of the world on which the oceans are distorted to allow for greater accuracy in representing the continents, combining the sinusoidal and equal-area projections.

What are the benefits of Goode homolosine projection?

In 1923, J. Paul Goode merged the Mollweide (Homolographic) projection and the Sinusoidal projection to create Goode’s Homolosine Interrupted. The advantage of this projection is each of the continents are the correct size and in proportion to one another. The disadvantage is distance and direction are not accurate.

What is the azimuthal projection used for?

The Azimuthal Equidistant projection is used for radio and seismic work, as every place in the world will be shown at its true distance and direction from the point of tangency.

Is Mercator a conformal map?

Mercator is a conformal map projection. Directions, angles, and shapes are maintained at infinitesimal scale. Any straight line drawn on this projection represents an actual compass bearing.

What does the world Mercator preserve?

Mercator found that to keep the rhumb lines straight he had to make lines of latitude move away from each other as they moved north and south of the equator. In order to do this, he created a projection that preserved the 90° angles between the latitude and longitude lines.

When was Goodes Homolosine map introduced?

The Goode homolosine projection was introduced by J. Paul Goode in 1923. It is available in ArcGIS Pro 1.0 and later and in ArcGIS Desktop 9.2 and later.

What is the most accurate map projection?

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. Japanese architect Hajime Narukawa invented this projection in 1999 by equally dividing a spherical surface into 96 triangles.

What is wrong with the Goode homolosine projection?

Goode homolosine is an equal-area (equivalent) projection. Shapes, directions, angles, and distances are generally distorted. There is no distortion along the central meridians and the equator. In the uninterrupted form, bulging meridians produce considerable shape distortion toward the edge of the projection.

What is one drawback of the Homolosine projection?

Disadvantages: The projection is neither equal area nor conformal. Because of the distortions introduced by this projection, it has little use in navigation or cadastral mapping […]

What does the Homolosine projection show best?

The Goode homolosine projection (or interrupted Goode homolosine projection) is a pseudocylindrical, equal-area, composite map projection used for world maps. Its equal-area property makes it useful for presenting spatial distribution of phenomena.

What map projection does NASA use?

The current version of G. Projector is 3.0. 2, released 2021-10-08.
