Can I stack/overlay 3D surfaces in Surfer?

Yes, you can both stack 3D surface maps in Surfer and you can overlay them. Stacking maps aligns the map frames according to their XY coordinates, so they are still two independent and separate maps. Overlaying puts both surface layers into the same map frame, so the surfaces are oriented correctly relative to each other and they use the same set of axes.


To stack 3D surface maps in Surfer, vertically move them to the desired spacing, then select them all and click Map Tools | Map Tools | Stack Maps. You do need to have multiple map frames selected for this command to be active.

 A few notes when stacking 3D surfaces:

  1. The map view properties should be the same for all maps. For example:
    1. Select Map in the Contents window for one of the 3D surfaces.
    2. In the Properties window, note the Projection, Rotation and Tilt values on the View page and note the X Scale and Y Scale Length on the Scale page.
    3. Select Map in the Contents window for another 3D surface.
    4. In the Properties window, set the same View and Scale properties you made note of in step 1b.
    5. Repeat steps 1c and 1d for the other surfaces.
  2. The maps are stacked according to their XY coordinates, so the surface maps need to be in the same coordinate system.


To overlay 3D surfaces in Surfer, select them all and click Map Tools | Map Tools | Overlay Maps.
