What is planar projection used for?
Planar projections are used most often to map polar regions.
Some Planar projections view surface data from a specific point in space.
The point of view determines how the spherical data is projected onto the flat surface..
What is the Peters Projection most useful for?
Maps not only represent the world, they shape the way we see it. The revolutionary Peters Projection map presents countries in their true proportion to one another: it has been adopted by the UN, aid agencies, schools and businesses around the world.
What are the disadvantages of the Robinson projection?
List of the Disadvantages of the Robinson ProjectionDistortions exist on the edges of the map. … It offers limited benefits for navigation. … The Robinson projection is not equidistant. … It does not provide azimuthal support. … The projection suffers from compression in severe ways.More items…•
Why would a town planner use a map at the 1 24000 scale rather than?
Why would a town planner use a map at the 1:24,000 scale rather than a map at the 1:250,000 scale? The map at the 1:24,000 scale shows a much larger area. The map at the 1:24,000 scale is easily converted to non-metric measurements. … The map at the 1:250,000 scale shows too small of an area to see the whole town.
Which type of projection is best for someone studying Greenland?
The Mercator projection makes everything that is near the polar areas appear too large. The Mollweide projection distorts the size of the polar regions much less. To see the actual size of Greenland, look at a globe.
What are the pros and cons of the Peters Projection?
Advantages: On Peters’s projection, […], areas of equal size on the globe are also equally sized on the 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.
Which projection does National Geographic use now?
Mollweide projectionCartographers at National Geographic chose to use a version of the Mollweide projection for their map highlighting ocean floors, published as the map supplement in the September 2012 issue of National Geographic magazine. This Mollweide projection is referred to as a pseudocylindrical projection.
What are the pros and cons of a 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.
Why do many geographers prefer the Robinson projection?
Geographers prefer the Robinson Projection because it shows the size and shape of most of the land quite accurately. The sizes of the oceans and and distances were also very accurate.
What is wrong with the Robinson projection?
The Robinson projection is neither conformal nor equal-area. It generally distorts shapes, areas, distances, directions, and angles. The distortion patterns are similar to common compromise pseudocylindrical projections. Area distortion grows with latitude and does not change with longitude.
What are the problems with distortion when using a Mercator projection?
Although the linear scale is equal in all directions around any point, thus preserving the angles and the shapes of small objects, the Mercator projection distorts the size of objects as the latitude increases from the equator to the poles, where the scale becomes infinite.
Which map projection is the most accurate?
AuthaGraphAuthaGraph. This is hands-down the most accurate map projection in existence. In fact, AuthaGraph World Map is so proportionally perfect, it magically folds it into a three-dimensional globe. Japanese architect Hajime Narukawa invented this projection in 1999 by equally dividing a spherical surface into 96 triangles.
What is controversial about the Peter’s Projection?
The Peters Projection map, which claimed to show the world in a more accurate, equal-area fashion. … The thing is, cartographers agreed that the Mercator map was outdated, inaccurate, and wasn’t the best way to represent the world’s landmasses.
Does the Robinson projection map show the size of the continents accurately?
The shape and size of the continents are shown accurately, but the water areas are expanded to fill the extra space. Tell students that this projection map was created by the American cartographer Arthur Robinson. … Students should notice that the latitude and longitude lines on this map are in increments of 15°.
Why is Robinson better than Mercator?
Unlike the Mercator projection, the Robinson projection has both the lines of altitude and longitude evenly spaced across the map. … In opting for a more pleasing appearance, the Robinson projection ‘traded’ off distortions – this projection is neither conformal, equal-area, equidistant nor true direction.
What spatial characteristics does the Robinson projection preserve?
A Pseudocylindrical projection that preserves neither scale nor area, but which presents an aesthetically pleasing view of the entire world. The Robinson projection is unlike most other projections in that it is not constructed by a mathematical formula used to transform coordinates systems.
When would you use a Robinson projection?
The Robinson projection is unique. Its primary purpose is to create visually appealing maps of the entire world. It is a compromise projection; it does not eliminate any type of distortion, but it keeps the levels of all types of distortion relatively low over most of the map.
