Also known as Vertical NearSide Perspective or Vertical Perspective, this projection is similar to the Orthographic projection in that its perspective is from space. In this projection, the perspective point is not an infinite distance away; instead, you can specify the distance. The overall effect of this projection is that it looks like a photograph taken vertically from a satellite or space vehicle.

Planar perspective projection. The distance above the earth is variable and must be specified before the projection can be calculated. The greater the distance, the more closely this projection resembles the Orthographic projection. All aspects are circular projections of an area less than a hemisphere.
A single point anywhere on the globe.
The actual range depends on the distance from the globe. In all cases, the range is less than 90° from the center.
