In addition the result alsoshows the minimum variation of polygon shapebetween the new and the existing boundary andwhich is considered to be very satisfactory.öCONCLUSIONA newly improved method of boundarydetermination is identified in this paper. A newkariah boundary for Muhammadiah Mosque inArau, Perlis is being proposed. The proposedsolution, outline an organization of the spatialbased data on the GIS capabilities to generatethe kariah boundary. By using this approach, itis anticipated that each kariah boundary will beformed in a more informed manner. Combination ofvarious approaches has its own unique implicationwith respect to individual location geographicmatters. However in this case study it is clearthat all models combination give better result forthe kariah. In turn, this approach would enablerapid and efficient techniques for the boundaryanalysis.ööööööööööModel A = Thiesseen Polygon B = Network Polygon C = Matching AreaAdvantages Equidistance boundary Shortest and optimum route Equidistance all cornersDisadvantages Regardless Legal boundaries Regardless Legal boundaries Regardless Legal boundariesRegardless physical barriers Regardless physical barriers Regardless physical barriersPolygon shape is look odd (linear area)Table 2 : Results from Basic Polygons Analysis
