One advantage of the surface map over the wireframe map is that you can choose the frequency of the mesh lines (every line, every other, every 5th, etc.). Another advantage is that you can set the map limits for a surface map, which you cannot do for a wireframe map. Additionally, surface maps don't show blanked areas, where wireframe maps do. On the other hand, wireframe maps are vector images (not bitmap images), so the resolution may be better than for surfaces maps.
