Dear all, Following my previous mail, I like just to point out (for the sake of precision and completeness) that among the projective projections of the sphere there is also the so called perspective projection, something resembling the third ptolemaic projection, but it is only a sort of mental exercise and a procedure allowed by the assumptions of projective geometry but of no practical use. In my knowledge no one has never drawn it (geometrically!). Nevertheless, it is the fourth projective projection of the sphere. vladimiro Il giorno 26/set/2010, alle ore 22.39, Luis Angel Robles Macias ha scritto: > This is a MapHist list message (when you hit 'reply' you're replying to the > whole list) > o + o + o + o + o + o + o + o + o + o + o + o + o + o + o + o + o + o + o + > > Dear Maphisters, > > I am trying to obtain the following short article published in 1962: > > Title: A method of plotting meridians and parallels on the Gnomonic projection > > Author: R.J.
