Miller Cylindrical is a modification of the Mercator projection. It is similar to the Mercator from the Equator to 45°, but latitude line intervals are modified so that the distance between them increases less rapidly. Thus, beyond 45°, Miller Cylindrical lessens the extreme exaggeration of the Mercator. Miller Cylindrical also includes the poles as straight lines whereas the Mercator does not.
All meridians are straight lines.
All parallels are straight lines.
Meridians are parallel and equally spaced, the lines of latitude are parallel, and the distance between them increases toward the poles. Both poles are represented as straight lines. Meridians and parallels intersect at right angles (Environmental Systems Research Institute, 1992).
While the standard parallels, or lines, that are true to scale and free of distortion, are at latitudes 45°N and S, only the Equator is standard.
Meridians and parallels are straight lines intersecting at right angles. Meridians are equidistant, while parallels are spaced farther apart the farther they are from the Equator. Miller Cylindrical is not equal-area, equidistant, or conformal. Miller Cylindrical is used for world maps and in several atlases.
Miller Cylindrical Projection
This projection resembles the Mercator, but has less distortion in polar regions. Miller Cylindrical is neither conformal nor equal-area.
