The perspective of the Vertical Near-Side Projection views the globe from a specified distance rather than from an infinite distance as in the Orthographic projection. This perspective provides the overall effect of a photograph of the earth taken from a satellite or space vehicle. 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 located anywhere on the globe. The central meridian of the projection. The arial scale decreases with distance from the center. Arial scale is zero at the edge of the hemisphere. True direction from the point of tangency.
