Unlike other conic projections, no true secant form of the projection exists because using a secant cone does not yield the same scale along both standard parallels.
The Equidistant conic projection is a conic map projection.
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.
An example of the use of the rectifying latitude is the Equidistant conic projection.
An example of the use of the authalic latitude is the Albers equal-area conic projection.
The term "conic projection" is used to refer to any projection in which meridians are mapped to equally spaced lines radiating out from the apex and circles of latitude (parallels) are mapped to circular arcs centered on the apex.
Nimisha had had Helm make maps of Erehwon from space, a Mercator projection, a Goode's Homolo-sine, and a Lambert Azimuthal equal area for detailed views of smaller areas, plus modified cylindrical and conic projections for the hemispheres.
The final form of the equidistant conic projection was constructed by the French astronomer Joseph-Nicolas Delisle in 1745.
The Albers equal-area conic projection features no distortion along standard parallels.
The continents in the conic projections are a little distorted ... See it now?
