What is distorted in a polar map projection?
a North Pole Stereographic Projection will project from the South Pole. The projection is conformal (ie. local shapes are accurate) but scale and area are both distorted. Local angles are also accurate.
Which map projection is most distorted near the poles?
the Mercator projection
At latitudes greater than 70° north or south the Mercator projection is practically unusable, because the linear scale becomes infinitely large at the poles.
Which map projection has the most distortion?
In stereographic projections, the perspective point is located on the surface of globe directly opposite from the point of tangency of the plane. Points close to center point show great distortion on the map.
What is a disadvantage of a polar projection map?
Disadvantages: Peters’s chosen projection suffers extreme distortion in the polar regions, as any cylindrical projection must, and its distortion along the equator is considerable.
What properties of map projections are distorted and why?
There are four basic characteristics of a map that are distorted to some degree, depending on the map projection used. These characteristics include distance, direction, shape, and area.
Where does it distort the features most?
A conformal map distorts area—most features are depicted too large or too small. The amount of distortion, however, is regular along some lines in the map. For example, it may be constant along any given parallel.
Which project map creates maps that are distorted near the poles?
Criticisms of the Mercator Projection To keep longitude lines straight and maintain the 90° angle between the latitude and longitude lines, the Mercator projection uses varying distances between latitude lines away from the equator. As a result, the Earth’s poles and landmasses closest to them are distorted.
Which map projection has the least distortion?
globe
The only ‘projection’ which has all features with no distortion is a globe. 1° x 1° latitude and longitude is almost a square, while the same ‘block’ near the poles is almost a triangle. There is no one perfect projection and a map maker must choose the one which best suits their needs.
What is good about the polar projection?
Figure6: this projection is very useful for displaying world maps because it shows the true shapes and areas of countries and continents, with only small distortions as compared to the Mercator or other global projections. Shearing and relative area increase toward the map’s east and west edges and near the poles.
What are the benefits and drawbacks 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. Who uses it? Researchers use Equal-Area maps to compare land sizes of the world.
