| Abstract: | Taking the Jiangsu Province coastline as an example, the midpoint subdivision interpolation method is used to explore the simulated coastline generation method, and the relevant fractal dimension values are also computed. Based on the above method, a practical fractal simulation procedure is designed, and the simulation process and function of the procedure are analysed. The procedure can be used for simulating and making a fractal dimension computation of the existing gridded or vector graphs of coastline, and also for saving, retrieving and scaling the coastline graphs. |
