Polyconic Projection

The polyconic projection is favored in some instances for its ability to represent mid-latitude regions with reasonably accurate area and shape when compared to other conic projections. The fact that each parallel has true scale makes it advantageous for certain mapping applications, such as cadastral and survey maps where precision for local

Polyconic Projection. This now obsolete map projection uses an infinite number of cones tangent to an infinite number of parallels. This type of protection is generally used for countries that span along a longitudinal extent. In a polyconic projection, all meridians except the central one have curved lines.

the Polyconic projection is an example of a basic scheme of projection, as fundamental as the cylindrical, conic, or azimuthal. The blue line indicates the line or point of contact between the reducible surface to which the projection is made and the sphere. In the case of the Polyconic, this contact is along a great circle, so in a sense

This Video deals with the construction of Polyconic Projection in a very lucid way.The following topics have been taken into account1. About Polyconic Proj

The polyconic projection is neither conformal nor equal-area. The projection is a derivation from the simple conic projection, but with every parallel true to scale similar to the Bonne's equal-area projection. The polyconic projection is projected onto cones tangent to each parallel, so the meridians are curved, not straight figure below.

Learn about the polyconic projection, a map projection used for maps of the United States and its regions since the 19th century. It has true scale on the central meridian and parallels, and is defined by a continuously varying cone.
