| 摘 要： | 从线要素缓冲区构建的角度出发,通过挖掘线要素各线段(局部)缓冲区之间的空间几何关系,构建了线要素缓冲区分段解算模型。在此基础上提出了基于分段解算模型的线要素缓冲区生成算法,阐述了该算法的基本原理和实现步骤,并在VC++环境下对算法进行了验证。

| Abstract: | After having analyzed the spatial relationships among （part） line buffer from the viewpoint of line feature buffer construction, the paper has brought forward the subsection solution model, and applied the model into line feature buffer construction. Besides, the paper also expatiates the keystone and solution steps of the algorithm. At last,under the condition of VC＋＋, some experiments have been done to validate the algorithm. |
