Describe the differences between a Mercator projection and a gnomonic projection?

∙ 9y ago
A Mercator projection map is the most familiar and common to usage in primary education systems. Mercator projections model the continents and oceans into a flattened and rolled cylindrical format. In comparison a Gnomonic projection is also two dimensional and flat but it uses lines which are actual representation of point-to-point s indicating true distance. Another significant difference is scale as Mercator's can represent the entire earth whereas Gnomonics represent a geographical limited area. Lastly Mercator's have the difference of distortion and under representing the actual sizes of Greenland and Continental Africa.

Compare and contrast mercator and gnomonic projections?
Compare: Both Mercator and Gnomonic projections are commonly used for nautical purposes, such as routes for ships to take.Contrast: Gnomonic projections usually display a small area of the Earth, whereas a Mercator projection displays the entire Earth, but with distortions at the poles.
Is a gnomonic projection a rectangle?
no
What were the two early means of showing the earths surface?
The Mercator Projection, developed by Flemish geographer Gerardus Mercator, was widely used as the standard two-dimensional projection of the earth for world maps until the late 20th century, when more accurate projections were formulated. Mercator was also the first to use and popularize the concept of the atlas as a collection of maps.
What is the advantage of a gnomonic projection?
a gnomonic map makes countries look longer, distorted, and hard to understand
Where are land masses distorted on a gnomonic projection?
near the poles
What is used locate places on Earth's surface?
A Map, in one one of these different types of projections: Mercator, Gnomonic, and Polyconic. Mercator - Shows the whole world except for the poles. Gnomonic - A circle projection showing, most often, the poles but sometimes other small places of the earth. Polyconic - Made as if a cone of paper had been wrapped around the earth, often used for places in the middle latitudes, such as the United States.

Are parallels parallel on a gnomonic projection?
a parallel is two line that never cross each other
Map projection is used for sea travel?
A map projection that is used for sea travel includes the gnomonic projection. This was most often used to find the shortest routes between points on a sphere.
What is the most common map projection used?
The most common map projections are based on three main geometric shapes: 1) Sphere to a Plane 2) Cylindrical Projections, 3) Conic Projections.
IsTransverse Mercator chart suitable for polar navigation use?
No - use a Lambert conformal or better yet use a polar gnomonic chart . mercator charts are not good for higher latitudes , typically above 70' .
