## What are the advantages of Mercator projection?

Advantages of Mercator’s projection: – preserves angles and therefore also shapes of small objects – close to the equator, the distortion of lengths and areas is insignificant – a straight line on the map corresponds with a constant compass direction, it is possible to sail and fly using a constant azimuth – simple …

## What is the importance of using Mercator sailing?

Mercator sailing is used to calculate the position after sailing along a rhumb line other than in a North-South or East-West direction. It is also used to find course and distance between two known positions.

## Why is a Mercator projection best for sea travel?

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 Mercator sailing in navigation?

[mər′kād·ər ‚sāl·iŋ] (navigation) A method of solving the various problems involving course, distance, difference of latitude, difference of longitude, and departure by considering them in the relation in which they are plotted on a Mercator chart.

## What is wrong with the Mercator projection?

Mercator maps distort the shape and relative size of continents, particularly near the poles. … The popular Mercator projection distorts the relative size of landmasses, exaggerating the size of land near the poles as compared to areas near the equator.

## What is the difference between plane sailing and Mercator sailing?

* It is similar to plane sailing except that plane sailing is used for small distance. * In mercator sailing the d’lat is expressed in longitudinal units, which is the difference of meridianal parts. * In plane sailing the d’long is expressed in latitude units or Nautical miles.

## What are the two categories of Mercator sailing?

In broad terms, there are two main types of sailing, namely, the Rhumb Line sailing and the Great Circle sailing.

## When planning to cross an ocean is it always best to use great circle sailing?

Great Circle Sailing is used for long ocean passages. For this purpose, the earth is considered a perfect spherical shape; therefore, the shortest distance between two points on its surface is the arc of the great circle containing two points.

## What are the 4 types of map projections?

What Are the Different Types of Map Projections?

Rank ﻿Map Projection Name Examples
1 Cylindrical Mercator, Cassini, Equirectangular
2 Pseudocylindrical Mollweide, Sinusoidal, Robinson
3 Conic Lambert conformal conic, Albers conic
4 Pseudoconical Bonne, Bottomley, Werner, American polyconic

Advantage: The Mercator map projection shows the correct shapes of the continents and directions accurately. Disadvantage: The Mercator map projection does not show true distances or sizes of continents, especially near the north and south poles.
