Question

What is zenithal mapping projection ? Present its complete classification scheme.

Answer 1

Answer:

Explanation:

Zenithal projections (also known as azimuthal projections) are a class of projections in which the surface of projection is a plane. The native coordinate system is such that the polar axis is orthogonal to the plane of projection, whence the meridians are projected as equispaced rays emanating from a central point, and the parallels are mapped as concentric circles centered on the same point.
