This paper proposes a new method to improve the characteristics of the triangulated irregular network (TIN) map deformation. Specifically, the similarity transformation-based interpolation method is adopted to improve the characteristics of the smoothness of the point-position transformation function from the original map to the deformed map. The experimental results show that the proposed method actually realizes the smoothness on the edges of the triangles in the TIN. However, it is also indicated that unsmoothness still remains only on the vertices of the triangles.
