Because the outer Elevation or depression that limits the range of reflection, other surveys or depressions does not cross or merge with them, but at best their edge possibly coinciding with an edge of a neighboring elevation or depression, the corresponding reflection area of the reflector is clearly delimited. When the reflection area structure has several self-contained elevations or depressions, which surround each other, the outermost of these elevations or depressions sets the edge of the Reflection range fixed.
