 I.e. a proj-string consists of a projection specifier, ``+proj``, a number of
 parameters that applies to the projection and, if needed, a description of a
 datum shift. In the example above geodetic coordinates are transformed to
-projected space with the :doc:`Mercator projection<operations/projections/merc>` with
+projected space with the :doc:`Mercator projection<../operations/projections/merc>` with
 the latitude of true scale at 56.5 degrees north on the GRS80 ellipsoid. Every
 projection in PROJ is identified by a shorthand such as ``merc`` in the above
 example.
