    Re: Pointless? Optimisation - Intercept Plotting
    From: John D. Howard

    Tony,

    The scale for the intercept does not depend on the latitude.  It is in nautical miles, the same at the equator or 89 degrees North.

    The only thing that you would need latitude for is if ( and only if ) you draw other lines of longitude.  I almost never need another longitude line.
