From John Vidar Larring, "Added vertical scale as a property of osgTerrain::Terrain. Lets you configure vertical scale when initializing the terrain model. E.g:

Browse Source 
osgTerrain::Terrain* terrain = findTopMostNodeOfType<osgTerrain::Terrain>(model.get());
  if (!terrain)
  {
      terrain = new osgTerrain::Terrain;
      terrain->addChild(model.get());
      terrain->setVerticalScale(2.0f);
      model = terrain;
  }
  viewerWindow->setSceneData(model.get());
