What are the advantages and disadvantages of Mercator projection?

What are the advantages and disadvantages of Mercator projection?

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.

What is the difference between normal Mercator and Transverse Mercator?

The Mercator uses an upright cylinder for its map projection. The Transverse Mercator takes a cylinder and places it on its side (rotates it 90°), as pictured below – which is how the term “transverse” is derived. However, the Universal Transverse Mercator places this cylinder 60 times for each UTM zone..

What are 3 kinds of maps?

For purposes of clarity, the three types of maps are the reference map, the thematic map, and the dynamic map.

What are the types of map projection?

Introduction

Projection	Type	Key virtues
Lambert Conformal Conic	conic	conformal
Mercator	cylindrical	conformal and true direction
Robinson	pseudo-cylindrical	all attributes are distorted to create a ‘more pleasant’ appearance
Transverse Mercator	cylindrical	conformal

What are advantages and disadvantages of map projections?

Advantage: The Equal-Area map projection show the correct sizes of landmasses and continents. Disadvantage: The Equal area map causes the shapes of landmasses to be altered and forced into curves.

What are the advantages of the 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 …

Which of these is a disadvantage of a Mercator projection map?

One disadvantage of using the Mercator projection is that it distorts size of areas, particularly as you get closer to the North and South Poles.

What are the advantages and disadvantages of a cylindrical map?

The advantages of a cylindrical map is that it shows accurate direction and shapes. The disadvantage is that it enlarges and distorts by exaggeration of size. Why is the Mercator projection problematic?

What are the different types of map projection?

1 Equal-area cylindrical projection. 2 Equidistant cylindrical projection. 3 Mercator projection. 4 Miller projection. 5 Plate Carrée projection. 6 Universal transverse Mercator projection.

What are the pros and cons of a conical map?

Conical Projections: Pros: These maps are very good for mapping regions that are primarily West-East in dimension like the United States. That is because a cone, when developed, is itself wider than tall. Cons: The basic con is that a single cone cannot show the entire globe. They will typically show a little more than a hemisphere.

What are the disadvantages of the Mercator projection?

Disadvantages: Mercator projection distorts the size of objects as the latitude increases from the Equator to the poles, where the scale becomes infinite. So, for example, Greenland and Antarctica appear much larger relative to land masses near the equator than they actually are. What is good about the Mercator projection?
