The Help for Texture had this code in which I added a geotiff
cylindrical projection of the moon.  Can anyone suggest a method of
selecting a portion of this so I can do a ListPlot3D and then export
as stl.  Here is an example:

 moon = SphericalPlot3D[1, {u, 0, Pi}, {v, 0, 2 Pi}, Mesh -> None,
  TextureCoordinateFunction -> ({#5, 1 - #4} &),
  PlotStyle ->
   Directive[Specularity[White, 10],
    Texture[Import[
      "http://finkh.files.wordpress.com/2011/03/ldem_4.png";]]],
  Lighting -> {White}, Axes -> False, Boxed -> False,
  RotationAction -> "Clip"]
