 our model, but we want to map this to a 2D discretization to do our forward
 modeling. We will also assume that we are working in log conductivity still,
 so after the transformation we want to map to conductivity space.
-To do this we will introduce the vertical 1D map (:class:`SimPEG.Maps.Vertical1DMap`),
+To do this we will introduce the vertical 1D map (:class:`SimPEG.Maps.SurjectVertical1D`),
 which does the first part of what we just described. The second part will be
 done by the :class:`SimPEG.Maps.ExpMap` described above.
