Werner drawing

A world map by the Werner drawing.

The Werner drawing (Werner ずほう) is a kind of the map projection and is 擬円錐図法 which is the original product. I am called ヴェルネル drawing, stub - Werner drawing, studio biUsu - Werner drawing, Warner drawing, the ヴァルトゼーミュラー drawing.

I was moved in about 1500 by a John studio bimortar, and Martin ヴァルトゼーミュラー used it in 1507 and was introduced by John Werner in 1514.

When assume 1, the reduced scale on the central line of longitude 1 at a radius of the earth; latitude${\displaystyle \phi}$Radius that the の parallel assumes the North Pole the center and is proportional to digression from the North Pole${\displaystyle \pi /2-\phi}$It was の kindred spirit arc, but matched the length of the parallel with the true head on the earth${\displaystyle 2\pi \cos \phi}$I let this allot とし, the longitude proportionally. Therefore, it is the original product. I agree that I took a standard parallel of the Bonne projection in the pole. There is a point like the azimuthal equidistant projection, and the distance from the pole playing a key role to each point is right.
