7. PROJECTION OF CONSTRAINT (CUT-OFF) LINE The cut-off line of the Outer Limits of Continental Shelf in the Area of North West of Sumatra is based on the 350M-line from the baselines. The distance is measured using the Mapping Software applying the Geodetic Technique.

8. DETERMINATION OF FOS The FOS determination is based on the principle of Maximum Change of Gradient applied to existing bathymetric data.

33. IDENTIFICATION OF THE LOCATION OF THE FOOT OF SLOPES Article 76 paragraph 4 (b) provides basic rule to determine the foot of the continental slope: “ (b) In the absence of evidence to the contrary, the foot of the continental slope shall be determined as the point of maximum change in the gradient at its base.” The fundamental requirements posed by the implementation of this rule are: The identification of the region defined as the base of the continental slope; and The determination of the location of the point of maximum change in the gradient at the base of the continental slope.

34. IDENTIFICATION OF THE LOCATION OF THE FOOT OF SLOPES The simplest method to determine the FOS is to build a series of topographical vertical profiles by generating a line to the strike direction of the continental slope and to analyze their changes. Furthermore, the gradient and the second derivative of these topographical profiles can be calculated and the point with the maximum gradient change analyzed.
