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 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.


Which type of map projection shows all latitude and longitude lines as parell?

The cylindrical map projection, such as the Mercator projection, shows all latitude and longitude lines as parallel. However, this projection distorts the size of land masses the further they are from the equator.


What is projection has parallel latitude lines and parallel longitude lines?

A projection with parallel latitude lines and parallel longitude lines is known as a cylindrical projection. This type of projection preserves the shape of features along the equator and distorts them towards the poles. Examples include the Mercator and Miller cylindrical projections.


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 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.


What map has parallel lines of latitude and longitude?

A map with parallel lines of latitude and longitude is known as a Mercator projection map. This type of map is often used for navigation purposes due to its representation of straight lines of latitude and longitude, making it easier to measure distances and plot courses. However, the Mercator projection distorts the size of landmasses, especially near the poles.


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 horizontal scale of a mercator projection increase with latitude?

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 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.


How is distance measured in the mercator chart?

Distance on a Mercator chart is measured using the latitude scale, where each degree of latitude is equal to a specific distance in nautical miles. However, it's important to note that the Mercator projection distorts distances as you move towards the poles, elongating areas nearer the poles.
