Cylindrical Projection cylindrical projection  [map projections] A projection that transforms points from a spheroid or sphere onto a tangent or secant cylinder. The cylinder is then sliced from top to bottom and flattened into a plane.
s I. What is a ? A can be imagined in its simplest form as a that has been wrapped around a globe at the equator.
Cylindrical Projection A cylindrical projection of points on a unit sphere centered at consists of extending the line for each point until it intersects a cylinder tangent to the sphere at its equator at a corresponding point .

The Miller is a modified Mercator projection, proposed by Osborn Maitland Miller (18971979) in 1942. The parallels of latitude are scaled by a factor of 0.8, projected according to Mercator, and then the result is divided by 0.
Cylindrical Projection: Projection in which a surface is drawn as it would appear if projected on a cylinder wrapped around the Earth.
A is obtained by projecting the earth onto a cylinder. The cylinder is then slit open and laid out flat to produce the map.

s Cylindrical Equal Area Cylindrical EqualArea projections have straight meridians and parallels, the meridians are equally spaced, the parallels unequally spaced.
Other Cylindrical projections Pseudocylindrical projections are projections in which the parallels are represented by parallel straight lines, and the meridians by curves.
 Mercator One of the most famous map projections is the Mercator, created by a Flemish cartographer and geographer, Geradus Mercator in 1569.

[map projections] A whose lines of tangency or secancy follow neither the equator nor a meridian.
In a cylindrical projection, for example, the lines of latitude (parallels) of the selected ellipsoid are simply drawn as straight, parallel lines.
Other agencies began to use the Mercator in the early twentieth century. Later in the century, some agencies converted to the Lambert conformal conic projection for maps of the entire country.
For example, normal cylindrical projections are good for maps which are of greater extent eastwest than northsouth and in equatorial regions, while conic projections are better in midlatitudes; ...
The UTM projection is formed by using a transverse , i.e., the standard line runs along a meridian of longitude. The effect is to minimize distortion in a narrow strip running pole to pole.
Since these grids are features and spatially accurate, if you project a grid that was created using a cylindrical projection, for example, UTM or Mercator, and you change your coordinate system to a conic or equal area projection, ...
For s, the "normal" or "standard" aspect refers to when the cylinder is tangential to the equator (i.e., the axis of the cylinder is oriented northsouth).
A cylindrical projection is the simplest projection to plot long/lat coordinates onto, again with a minimum of conversion needed reducing processor overhead. For our purposes you can simply right click the image and "Save picture as ...
Instead of having the paper come to a simple point or line of tangency with the globe, you could cut the globe's surface (called secant), so that conic and s intersect the globe at two lines (latitude) and plane projections ...
