Robinson Projection Map

1. ROBINSON PROJECTION (MAP)

2. Arthur H. Robinson An American geographer and cartographer, who was a professor in the Geography Department at the University of Wisconsin-Madison rom 1947 untel he retired in 1980. He was born January 5, 1915 and died October 10, 2004)

3. Robinson called his projection as the O rthophanic projection (which means “right appearing”), but this name never caught on. In at least one reference book, this projection is termed the Pseudocylindrical projection with “Pole line”, which is highly descriptive (the “pole line” comes from the fact that the North and South Poles on a Robinson Projection are shown as lines and not points), but so unwieldily that it is not surprising that this name also failed to gain much acceptance. The projection was designed at the request of the Rand McNally Company using graphic design rather than mathematical equation development in the year 1963.

4. Professor Robinson did not develop this projection by developing new geometric formulas to convert latitude and longitude coordinates from the surface of the Model of the Earth to locations on the Map. Instead, Robinson used a huge number of trial-and-error computer simulations to develop a table that allows a cartographer to look up how far above or below a Robinson map’s equator a particular line of latitude will be located, and then to estimate where along this line a particular longitude will fall.

5. The central meridian is 0.5072 times the length of the projected equator and pole lines are 0.5322 as long as equator. The g raticule is symmetric across the equator and the central meridian. Graticule Usage 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.

6. Robinson’s projection comprise a map showing the poles as lines rather than points and more accurately portraying high latitude lands and water to the ratio.
