Abstract
In the process of determining the residential development planning, examination of the cost is required to investigate the efficiency of the project. In this paper, therefore, develop the system which materialize advanced planning examination through formulating the topographical design model which investigates the cost of a preparation that occupies majority of the budget. And in this study, we acquired the topographical data and displayed the topography by using Non-Uniform-Rational B-Spline. Therefore, we could reduce the work to acquired the topographical data and we could make the system to fit the topographical design model.
