Explore: Spherical Oblique

The oblique Mercator map projection is an adaptation of the standard Mercator projection. The oblique version is sometimes used in national mapping systems

Spherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the sides and angles of spherical triangles

In geometry, a spherical cap or spherical dome is a portion of a sphere or of a ball cut off by a plane. It is also a spherical segment of one base, i

latitude. Practical uses for the oblique projection, such as national grid systems, use ellipsoidal developments of the oblique Mercator in order to keep scale

small circle of fixed radius (e.g., 15 degrees angular radius). Sometimes spherical triangles are used.[citation needed] In the first half of the 20th century

An oblique prism is a prism in which the joining edges and faces are not perpendicular to the base faces. Example: a parallelepiped is an oblique prism
