1. polyconic projection

   The American polyconic map projection is a map projection used for maps of the United States and regions of the United States beginning early in the 19th century. It belongs to the polyconic projection class, which consists of map projections whose parallels are non-concentric circular arcs except for the equator, which is straight. Often the American polyconic is simply called the polyconic projection. The American polyconic projection was probably invented by Ferdinand Rudolph Hassler around 1825. It was commonly used by many map-making agencies of the United States from the time of its proposal until the middle of the 20th century. It is not used much these days, having been replaced by conformal projections in the State Plane Coordinate System.

1. polyconic projection

   A Polyconic projection is a type of map projection used for creating maps where the scale is preserved along the central meridian and all parallels. It involves an imaginary geometric process where each parallel or place of constant latitude is projected onto the map along a circular arc, resulting in a map where each parallel has its own true scale. This projection is often used for large scale maps covering small areas, like individual states or counties.

1. Polyconic projection

   Polyconic can refer either to a class of map projections or to a specific projection known less ambiguously as the American Polyconic. Polyconic as a class refers to those projections whose parallels are all non-concentric circular arcs, except for a straight equator, and the centers of these circles lie along a central axis. This description applies to projections in equatorial aspect. As a specific projection, the American Polyconic is conceptualized as "rolling" a cone tangent to the Earth at all parallels of latitude, instead of a single cone as in a normal conic projection. Each parallel is a circular arc of true scale. The scale is also true on the central meridian of the projection. The projection was in common use by many map-making agencies of the United States from the time of its proposal by Ferdinand Rudolph Hassler in 1825 until the middle of the 20th century. The projection is defined by: where is the longitude of the point to be projected; is the latitude of the point to be projected; is the longitude of the central meridian, and is the latitude chosen to be the origin at . To avoid division by zero, the formulas above are extended so that if then and .
