Designing a high-precision geographical map of Terengganu using Cubic Trigonometric B-Spline and Cubic Trigonometric Bezier

This study aims at creating a precise two-dimensional map of Terengganu by utilizing Cubic Trigonometric B-Spline (CTBS) and Cubic Trigonometric Bézier (CT-Bézier) which belong to a class of Computer-Aided Geometric Design (CAGD). The investigation uses the issue of the lack of precision in traditional methods of mapping, particularly with regard to when complex geographical attributes are represented. To overcome this, both CTBS and CT- Bézier were used since they are flexible with shape control and can provide smooth curves based on shape parameters. The primary goals of the project were to model the Terengganu map with the two techniques, find out the most appropriate shape parameters to make sure the curves are smooth and also find the most appropriate technique to provide accurate geographical modelling. The data collection involved the extraction of map outlines in Google Maps and 498 control points were located on the Terengganu boundary.
