a spherical conic or sphero-conic is a curve on the sphere, the intersection of the sphere with a concentric elliptic cone. It is the spherical analog...

planar conic sections also extend to spherical conics. If a sphere is intersected by another surface, there may be more complicated spherical curves....

A conic section, conic or a quadratic curve is a curve obtained from a cone's surface intersecting a plane. The three types of conic section are the hyperbola...

distances along all other parallels are stretched. Conic projections that are commonly used are: Equidistant conic, which keeps parallels evenly spaced along...

The intersection of an elliptic cone with a concentric sphere is a spherical conic. In projective geometry, a cylinder is simply a cone whose apex is...

In geometry, the conic constant (or Schwarzschild constant, after Karl Schwarzschild) is a quantity describing conic sections, and is represented by the...

A Lambert conformal conic projection (LCC) is a conic map projection used for aeronautical charts, portions of the State Plane Coordinate System, and...

projection's characteristics. Coordinates from a spherical datum can be transformed into Albers equal-area conic projection coordinates with the following formulas...
