Equidistant Conic projection
The Equidistant Conic projection is one of the simplest of all projections. Based on a cone, it is typically found in atlases of small countries and is used for portrayals of areas near to, but not overlapping, the equator. The equidistant conic projection has equally spaced straight meridians and equally spaced circular parallels, making scale is the same along all meridians. Commonly one or two parallels are chosen to have the same scale and have no distortion.
Neither equal-area, nor conformal (but an acceptable compromise for most temperate countries), this projection is defined arbitrarily instead of by a perspective process. It is the general case of both azimuthal equidistant and equidistant cylindrical projections..
