+    Pseudocylindrical Projection
+
+        Pseudocylindrical projections have the mathematical characteristics of
+
+        .. math::
+
+            \begin {array}
+
+            x &= f(\lambda,\phi)
+
+            y &= g(\phi)
+
+            \end {array}
+
+        where the parallels of latitude are straight lines, like cylindrical
+        projections, but the meridians are curved toward the center as they
+        depart from the equator. This is an effort to minimize the distortion
+        of the polar regions inherent in the cylindrical projections.
+
+        Pseudocylindrical projections are almost exclusively used for small
+        scale global displays and, except for the Sinusoidal projection, only
+        derived for a spherical Earth. Because of the basic definition none of
+        the pseudocylindrical projections are conformal but many are equal
+        area.
+
+        To further reduce distortion, pseudocylindrical are often presented in
+        interrupted form that are made by joining several regions with
+        appropriate central meridians and false easting and clipping
+        boundaries. Interrupted Homolosine constructions are suited for showing
+        respective global land and oceanic regions, for example. To reduce the
+        lateral size of the map, some uses remove an irregular, North-South
+        strip of the mid-Atlantic region so that the western tip of Africa is
+        plotted north of the eastern tip of South America.
