Why does horizontal scale of a mercator projection increase with latitude?
Wiki User
∙ 12y ago
The vertical (or latitude) scale increases with latitude, keeping the hoizontal (longitude) constant. This is in order to make the lines of longitude parallel on the chart, instead of, in reality, converging toward the poles.
This allows courses to be plotted and drawn on the chart, as straight lines crossing the lines of longitude at the same angle.
Known as 'plane sailing'. ie. it is on a plane (flat surface) not a globe.

What is the Mercator projection map?
The Mercator system is a cylindrical map projection. It is essentially the shape of globe on a flat surface. It was first designed by mapmaker Gerardus Mercator in 1569.
What kind of map is a rectangular representation of Earth that shows accurate directions but distorts sizes and distances?
mercator projection
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.
What is used to 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.
What is system for mapping the round earth on a flat surface called?
mercator
What is the advantage of a Mercator projection?
The Mercator projection preserves straight lines, making it useful for navigation. It also shows true direction, making it valuable for sailors and pilots. Additionally, it accurately represents shapes and angles near the equator.
What is the advantage of Mercator projection?
The ability of the Mercator projection to allow straight and constant course lines. Or longitude and latitude lines.
What projection shows all lines of latitude and longitude as straight lines?
The Mercator projection does that.
What is projection has parallel latitude lines and parallel longitude lines?
'po';op'[ 'po';/l.;;
Which type of map projection shows all latitude and longitude lines as parell?
The Mercator projection
What is the size of Congo in mercator projection?
A mercator projection is defined as a projection of a map of the world onto a cylinder in such a way that all the parallels of latitude have the same length as the equator, used especially for marine charts and certain climatological maps. Congo, as depicted in mercator projection, is small.
Why does the horizontal scale of a Mercator projection increase with latitude?
whenever you try to map a curved (spherical) surface onto a flat map you get distortion. The only way to map a sphere accurately is to make a globe, all other methods are only appoximations.
What type of map is a Mercator map?
Mercator is not a map, but a map projection, i.e. a way of representing the continents on a map. The Mercator projection is only accurate between 30 degrees north and south latitude. The further away you go from that point, the greater the exaggeration.
What type of projection is a Mercator projectio?
It is a Mercator projection!
What map would a sailor use?
The Mercator projection is the standard for nautical navigation.
What are shown as straight lines on a Mercator projection called?
The parallels of latitude and the meridians of longitude are all straight lines on the Mercator projection. That's why Greenland looks bigger than South America.
How are a mercator projection and an Robinson projection map the same?
what similarity about the mercator projection and the robinson projection?
