Oblique projection is a simple type of technical drawing of graphical projection used for producing two-dimensional (2D) images of three-dimensional (3D) objects. The objects are not in perspective and so do not correspond to any view of an object that can be obtained in practice, but the technique yields somewhat convincing and useful results.
An oblique combination of the sinusoidal and Mollweide projections. 1906 Eckert II: Pseudocylindrical Equal-area Max Eckert-Greifendorff: 1906 Eckert IV: Pseudocylindrical Equal-area Max Eckert-Greifendorff: Parallels are unequal in spacing and scale; outer meridians are semicircles; other meridians are semiellipses. 1906 Eckert VI ...
oblique Mercator projection. The oblique Mercator map projection is an adaptation of the standard Mercator projection. The oblique version is sometimes used in national mapping systems. When paired with a suitable geodetic datum, the oblique Mercator delivers high accuracy in zones less than a few degrees in arbitrary directional extent.
In oblique projections the parallel projection rays are not perpendicular to the viewing plane as with orthographic projection, but strike the projection plane at an angle other than ninety degrees. In both orthographic and oblique projection, parallel lines in space appear parallel on the projected image.
These projections are also used to represent spatial figures in two-dimensional drawings (see oblique projection), though not as frequently as orthogonal projections. Whereas calculating the fitted value of an ordinary least squares regression requires an orthogonal projection, calculating the fitted value of an instrumental variables ...
A Mercator map can therefore never fully show the polar areas (but see Uses below for applications of the oblique and transverse Mercator projections). The Mercator projection is often compared to and confused with the central cylindrical projection , which is the result of projecting points from the sphere onto a tangent cylinder along ...

In an oblique projection (at right), the projection lines are at a skew angle to the image plane. Every parallel projection has the following properties: It is uniquely defined by its projection plane Π and the direction v → {\displaystyle {\vec {v}}} of the (parallel) projection lines.
