AUTHENTICITY: This is an authentic antique print, published at the date stated above. I do not offer reproductions. It is not a modern copy.

RETURNS POLICY: I offer a no questions returns policy. All I ask is that you pay return shipping and mail back to me in original condition. BACKGROUND INFORMATION: A gnomonic map projection displays all great circles as straight lines, resulting in any straight line segment on a gnomonic map showing a geodesic, the shortest route between the segment's two endpoints. This is achieved by casting surface points of the sphere onto a tangent plane, each landing where a ray from the center of the sphere passes through the point on the surface and then on to the plane. No distortion occurs at the tangent point, but distortion increases rapidly away from it. Less than half of the sphere can be projected onto a finite map. Consequently, a rectilinear photographic lens, which is based on the gnomonic principle, cannot image more than 180 degrees.Please explore my ebay shop for more antique prints.
