Which projection is suitable for polar regions?

Which projection is suitable for polar regions?

The equator is a circle centered at the pole. The International Meteorological Commission (Gregg and Tannehill 1937) recommends a conformal (orthomorphic) projection to be used for synoptic meteorology and proposes the Stereographic projection for polar regions on a plane cutting the sphere at 60°.

What is azimuthal projection used for?

The Azimuthal Equidistant projection is used for radio and seismic work, as every place in the world will be shown at its true distance and direction from the point of tangency.

What is the Mercator projection used for?

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 the biggest problem with the Mercator projection?

Because the linear scale of a Mercator map increases with latitude, it distorts the size of geographical objects far from the equator and conveys a distorted perception of the overall geometry of the planet.

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 wrong with the Robinson projection?

Distortion. The Robinson projection is neither conformal nor equal-area. It generally distorts shapes, areas, distances, directions, and angles. Area distortion grows with latitude and does not change with longitude.

What is wrong with the Peters Projection?

It replaces the traditional Mercator map style that many of us are familiar with. The Gall-Peters map shows the correct sizes of countries, but it also distorts them. Countries are stretched horizontally near the poles and vertically near the Equator, so although the size may be right, the shape definitely isn’t

What are the pros and cons of using a Mercator map projection?

Mercator

• Pros: Sailors loved it; preserves angles and directions in a small area.
• Cons: Bad for understanding the real size and shape of continents and countries.
• Related: After this video you’ll never trust a map again.
• Pros: The only ‘area-correct’ map of its time; got featured in The West Wing (S2E16)

What is a disadvantage of the Robinson map?

Robinson projections are not equivalent; they do suffer from compression. However, the amount of area distortion is generally low within about 45° of the equator. Conformality: The Robinson projection is not conformal; shapes are distorted more than they would be in a truly conformal projection.

What are the pros and cons of the Robinson projection?

Advantage: The Robinson map projection shows most distances, sizes and shapes accurately. Disadvantage: The Robinson map does have some distortion around the poles and edges.

What are the three types of globe?

Generally, there are three types of globes. Terrestrial globes detail geographical features of the Earth….Celestial Globe

• Stars in Canis Major.
• This Celestial Globe was acquired in June 1932 from Emil Hirsch of Munich, Germany.
• Another view of the Celestial Globe.

What is the difference between a map and a globe?

A map is a flat picture of a place. A map is easy to carry. You can fold a map and put it in your pocket. A globe is a big round ball that shows you the world.

What are the four different types of maps?

Types of Maps

• General Reference.
• Thematic Maps.
• Topographic Maps.
• Cadastral Maps and Plans.
• Navigation Charts.
• Series Maps.

Why do we use symbols on a map?

we draw symbols on maps because it is not possible to draw on a map the actual shape and sizes of different features such as building roads etc.so they are shown by some specific letters colours etc. We draw symbols on the map because we annot draw the actual shape and size of the features of the earth

How do you explain globe to a child?

A globe is a spherical model of Earth, of some other celestial body, or of the celestial sphere. Globes serve similar purposes to maps, but unlike maps, do not distort the surface that they portray except to scale it down. A globe of Earth is called a terrestrial globe.

What is the first globe?

The earliest extant terrestrial globe was made in 1492 by Martin Behaim (1459–1537) with help from the painter Georg Glockendon. Behaim was a German mapmaker, navigator, and merchant. Working in Nuremberg, Germany, he called his globe the “Nürnberg Terrestrial Globe.” It is now known as the Erdapfel.

What are the main features of Globe?

Features of globe A needle is fixed through the globe in a tilted manner, which is called its axis. Two points on the globe through which the needle passes are two poles – the North Pole and the South Pole. The globe can be moved around this needle from west to east just as the earth moves.

What is a map Short answer?

A map is an image of an area, usually of the Earth or part of the Earth. A map is different from an aerial photograph because it includes interpretation. If a map is on a piece of paper or a computer screen, it has to be projected.

What is MAP stand for?

What are two reasons why someone would use a physical map?

Physical maps show the earth’s features, like landscapes, mountains, rivers, valleys, deserts, lakes and oceans. They can also be used to show elevation, land use, infrastructure, and many other man-made features. Physical maps that show boundaries are also known as political maps.

What information might appear on both a physical and a political map?

A political map focuses on boundaries between entities, like countries, states or counties. They are generally brighter colors to easily distinguish the boundaries. A physical map focuses on the geography of the area and will often have shaded relief to show the mountains and valleys.
