1. Almost everything is accurately represented on the projection. Robinson`s projection was favorable because it produced a map on which everything was accurately depicted, except in the extreme areas along its edges. Despite existing inaccuracies, the mathematics of land masses still provides accurate representations of the average person. This was an advantage at a time when most other projections were based either on flat geography or on a crude misrepresentation along the various meridian points. Shear: The Robinson projection is not compliant; The shapes are more distorted than they would be in a truly conforming projection. However, the shapes are not very distorted about 45° north or south of the equator or about 45° from the central meridian of the map. Beyond these limits, the shape distortion can be very severe. 7. It is a projection that has great availability. After National Geographic began using the Robinson projection for its global mapping needs, it began to be used in classrooms around the world. It eliminates the visualization problems associated with the Mercator plate perspective, first created for navigation purposes in 1569.
It also eliminates duplication along the edges where Alaska appears in both sections, as well as a small part of Russia. Robinson even created the most important bodies of water for each continent to exhibit with his projection. You can see the Great Lakes and Great Salt Lake in North America, as well as several others in Africa, Europe and Asia with this map. When Robinson first created his map, he called it the “orthophanic projection,” which means “appear correctly.” It would be a name that never took hold. Most people associate these efforts directly with their Creator. The Robinson projection is a map projection of a world map that shows the entire world at once. It was created specifically for the purpose of finding a good compromise for the problem of easily presenting the entire globe as a flat image. [1] The European Centre for Disease Prevention and Control recommends using the Robinson projection to map the entire world. [12] Robinson`s projection is neither equal nor compliant, abandoning the two for a compromise. The Creator felt that this resulted in a better overview than what could be achieved by adhering to both. The meridians bend gently, avoiding extremes, but thus stretching the poles into long lines instead of leaving them as points.
[1] I decided to go back. I started with a kind of artistic approach. I visualized the most beautiful shapes and sizes. I worked with the variables to the point where it didn`t get better if I changed one of them. Then I found the mathematical formula to create this effect. Most cartographers start with mathematics. 3. The Robinson projection is not equidistant. The Robinson projection is not an equidistant map. That is, there are no points from which all distances are displayed exactly. You cannot select a specific range in this representation to determine the exact mileage. This means that it is useful for identifying continents, oceans and other important landmarks.
Trying to find specific islands or national borders is virtually impossible with this tool. The “Robinson projection” is undoubtedly the name of choice. Robinson`s projection is quite unique. Unlike all other projections, Professor Robinson did not develop this projection by developing new geometric formulas to convert the latitude and longitude coordinates of the Earth`s model surface into positions on the map. Instead, Robinson used a large number of trial and error computer simulations to develop a table that would allow a cartographer to look up how far above or below the equator of a Robinson map a given line of latitude will be, and then estimate (through a simple interpolation process) where a certain longitude will fall along that line. To date, no other projection uses this approach to create a map. Shape: The Robinson projection can be described as pseudocylindrical, but due to its unique method of development, it does not fit neatly into a well-known shape category. Robinson`s projection responded to a specific need at a certain point in our history. It met the needs of a company from a marketing perspective. The Central Intelligence Agency`s World Factbook uses Robinson`s projection in its maps of the political and physical world. Equidistance: The Robinson projection is not equidistant; There is no point or points from which all distances are accurately displayed.
4. It does not provide azimuthal support. This disadvantage of the Robinson projection means that there is no point or points on the map whose all directions are accurately represented. Even if you focus your attention on one of the poles, your southward movements follow a curvature instead of a direct line due to the distortion involved. This means that you can get a general idea of where to go if you want to travel, but the direction details are somewhat tweaked to improve the visualization of this tool. No other projection uses this approach to build a map today. Therefore, the advantages and disadvantages of Robinson`s projection are strong, even if its use has fallen out of favor in recent years. Case: The Robinson projection is essentially secantle, with tangent lines along latitudes 38° 0′ 0″N and 38° 0′ 0″S. 3. Robinson`s projection minimizes distortion over most of the map. Although the Robinson projection is not compliant, shapes you can find at about 45° north or south of the equator are usually accurately represented.
You`ll also experience this benefit when looking at items within 45° of the map`s central meridian. This means that you can look directly at this tool in its center to see a very representative figure of our planet, and then move from there to get an accurate visual representation as if you were looking at it from afar. The Robinson projection was developed in 1963 by Arthur H. Robinson in response to a call from the Rand McNally Company, which has since used projection in universal world maps. Robinson published details about the construction of the projection in 1974. The National Geographic Society (NGS) began using the Robinson projection for general world maps in 1988, replacing the Van der Grinten projection. [2] In 1998, NGS abandoned the Robinson projection in favor of the triple angular projection, because the latter “reduces the distortion of the Earth masses near the poles”. [3] [4] Variation within Robinson projections: Robinson projections differ from each other in the position of their central meridians.
