\begin{figure}\begin{center}\BoxedEPSF{maps/eqcy.epsf scaled 600}\end{center}\end{figure}

The Map Projection having transformation equations

$\displaystyle x$ $\textstyle =$ $\displaystyle (\lambda-\lambda_0)\cos\phi_1$ (1)
$\displaystyle y$ $\textstyle =$ $\displaystyle \phi,$ (2)

and the inverse Formulas are
$\displaystyle \phi$ $\textstyle =$ $\displaystyle y$ (3)
$\displaystyle \lambda$ $\textstyle =$ $\displaystyle \lambda_0+{x\over\cos\phi_1}.$ (4)
