I think I have found some typos in the libproj4 manual. Page 96, under the headline "Oblique Stereographic using intermediate sphere": * Equation (7.36) says "k)0", but the parenthesis does not match anything. I think it should have been "k_0" in the LaTeX source, so that the text would be "k0", with the zero as a subscript. * Equation (7.37) reads chi = ( cos c ... ) but something is missing. I looked in Snyder's book, and I think it should be chi = asin( cos c ...) (chi is that Greek letter that looks like a tall and narrow x, but isn't an x.) Page 78, table 6.1: Lambert Conformal Conic, in the general formula for rho, there is a numerator tan^n( pi/4 + phi1/2) but in the case phi1 = phi2, the analoguous numerator is written as tan^n( pi/4 + phi1) / 2 Should not these numerators be identical? They differ only in the placement of the ending parenthesis. Gerald Evenden wrote: > Please, please, please. Anyone finding errors in the previously reference > manual please notify this group.
