     {Gnomonic projection}, a projection of the circles of the


        sphere, in which the point of sight is taken at the center
        of the sphere, and the principal plane is tangent to the
        surface of the sphere. "The gnomonic projection derives
        its name from the connection between the methods of
        describing it and those for the construction of a gnomon
        or dial." --Cyc. of Arts & Sciences.
