Vertical Perspective

The Vertical Perspective projection represents a view of the Earth from space in which the view is from a point precisely facing the center of the Earth. This projection is therefore used to generate pictorial views of the Earth resembling those seen from space. It is an azimuthal projection that is neither conformal nor equal area. The central meridian and a particular parallel (if shown) are straight lines. Other meridians and parallels are usually arcs of circles or ellipses, but some may be parabolas or hyperbolas. If the point of perspective is above the sphere, less than one hemisphere may be shown.

The "Vertical Perspective" projection has the following parameters:

  • Longitude of the Center of the Projection

  • Latitude of the Center of the Projection

  • False Easting

  • False Northing

  • Height

Note: Only a spherical form of this projection is used. The semi-major axis of the ellipsoid will be used as the radius of the sphere.
