What is the Hobo-Dyer projection used for?
The Hobo-Dyer projection shows accurately the relative size of different land areas, while preserving north/south and east/west lines of bearing. It also gives the Southern Hemisphere visual prominence, imagining a globe that has been re-centred Down Under.
What is the Hobo-Dyer equal area projection map?
The Hobo–Dyer map projection is a cylindrical equal-area projection, with standard parallels (there is no north-south or east-west distortion) at 37.5° north and south of the equator. The map was commissioned in 2002 by Bob Abramms and Howard Bronstein of ODT Inc.
Who made the Robinson projection?
Arthur H. Robinson
The Robinson projection was devised by Arthur H. Robinson in 1963 in response to an appeal from the Rand McNally company, which has used the projection in general-purpose world maps since that time.
What type of map is the world population map?
Introducing: The Cartogram What’s a population cartogram? A cartogram is a visualization in which statistical information is shown in diagrammatic form. In this case, it’s a population cartogram, where each square in the map represents 500,000 people in a country’s population.
What is the Authagraph map?
Authagraph is an equal-area type world map projection that was invented by Japanese architect Hajime Narukawa in 1999. While conceptually in the category of an equal-area projection, it would require further subdivision to qualify as an actual equal-area map.
Which of the following types of distortions is not minimized by the Winkel Tripel projection?
Winkel choose the name Tripel because he had developed a compromise projection; it does not eliminate area, direction or distance distortions; rather, it tries to minimize the sum of all three.
Why is the Robinson projection better than the Mercator?
Unlike the Mercator projection, the Robinson projection has both the lines of altitude and longitude evenly spaced across the map.
What’s wrong with 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.
Is America bigger on the map?
In the Mercator projection, North America looks at least as big, if not slightly larger, than Africa. And Greenland also looks of comparable size. But in reality Africa is larger than both.
Why is Asia so populated?
According to the World Bank, the aging population and low fertility rates are to blame for the increase in population as 36 percent of the world’s population over 65 currently live in East Asia. The World Bank projects that the 211 million people living in East Asia will rise over time.
Why is Winkel Tripel the best?
The Winkel Tripel (used by National Geographic for world maps) was the best scoring of all the known projections with a normalized sum of squares of the six errors of 4.563. See Figure 1. The goal of the Winkel Tripel was to minimize isotropy, area, and distance errors.
What is lost by using the Mercator projection?
The Mercator projection doesn’t allow the charting of angles. The projection delivers a very distorted area. One example is that Greenland is shown to have the same size as Africa but in reality, Africa is much bigger than Greenland.
Why Israel is not clear on Google Maps?
The entire country of Israel is shown in low resolution in all U.S.-based mapping services, including Mapquest, Bing, etc. This is a result of the Kyl–Bingaman Amendment to the National Defense Authorization Act of 1997.
What is the Hobo Dyer projection of the world?
Hobo–Dyer projection of the world. The Hobo–Dyer map projection is a cylindrical equal-area projection, with standard parallels (there is no north-south or east-west distortion) at 37.5° north and south of the equator.
What type of projection is the Hobo-Dyer map?
The Hobo–Dyer map projection is a cylindrical equal-area projection, with standard parallels (where there is no north-south nor east-west distortion) at 37.5° north and south of the equator. The map was commissioned in 2002 by Bob Abramms and Howard Bronstein of ODT Inc., and drafted by cartographer Mick Dyer,…
What is the origin of the name Hobo Dyer?
The name Hobo–Dyer is derived from Bronstein and Abramms’s first names (Howard and Bob) and Dyer’s surname. The original ODT map is printed on two sides, one side with north upwards and the other with south upwards.
