Comparison of interpolation methods in digital height models

SUMMARY Comparison of Interpolation Methods in Digital Height Models The comparison of interpolation methods which is known as a digital representetive of variation of flood tide in space is a subject used in computer based modelling. In reality the comparison of interpolation methods is a specific work a surface which its mathematicial definition can be done to topographic surface of land. In this chapter Multiquadric and Piecewice Bilinear methods are used. These methods are interpolation methods used forming comparison of interpolation model. The cods obtains by using these two methods. They difference the values which read from map. They are tested and compared. In the end the advantages and disadvantages are examined. Key Words : Digital Height Models, Multiquadric Interpolation, Piecewice Bilinear Interpolation VI
