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. [Category=Geospatial ] ...
Cylindrical Projections I. What is a cylindrical projection? A cylindrical projection 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 .
Cylindrical Projections Introduction If the width of equatorial cylindrical maps is normalized by rescaling, then (since their spacing of meridians is identical) a projection's only defining feature is how its parallels are spaced.

The Miller cylindrical projection 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 0.8 to retain scale along the equator.[1] Hence: ...
cylindrical projection A map projection, in which the surface of the Earth is drawn as it would appear if projected on a cylinder wrapped around the earth in a northsouth direction. Compare with transverse cylindrical projection . dangle ...
Cylindrical Projection: Projection in which a surface is drawn as it would appear if projected on a cylinder wrapped around the Earth.
Cylindrical projection A cylindrical projection is obtained by projecting the earth onto a cylinder. The cylinder is then slit open and laid out flat to produce the map.
Cylindrical Projection: World Latitude and Longitude (Outline Map Printout) An outline map of world latitudes and longitudes to print (a cylindrical projection  it has straight lines of latitudes and longitude, but the areas near the poles are exaggerated in size).
Cylindrical Projections Cylindrical Equal Area Cylindrical EqualArea projections have straight meridians and parallels, the meridians are equally spaced, the parallels unequally spaced. There are normal, transverse, and oblique cylindrical equalarea projections.
Other Cylindrical projections Pseudocylindrical projections are projections in which the parallels are represented by parallel straight lines, and the meridians by curves. Examples are the Sinusoidal, Eckert, Winkel, Mollweide, DeNoyer and the Robinson projection.
Cylindrical Projection  Mercator One of the most famous map projections is the Mercator, created by a Flemish cartographer and geographer, Geradus Mercator in 1569.
Cylindrical projections  A class of map projection that projects part of the globe onto a cylindershaped surface.

Different cylindrical projection orientations: The most common cylindrical projection is the Mercator projection, which is the basis of the UTM (Universal Transverse Mercator) system. Planar (Orthographic) ...

[map projections] A cylindrical projection 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 cylindrical projection 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 cylindrical projection, 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. UTM divides the earth into poletopole zones 6 degrees of longitude wide.
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 cylindrical projections, 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).
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 cylindrical projections intersect the globe at two lines (latitude) and plane projections create a single circle.
