| 摘 要： | 岛群在自动综合的时候,要保持岛群的分布密度、密度对比、总轮廓以及岛群总的延伸方向不变。通过对岛群边界线的确定,实现岛群的化简。岛群外围边界的化简采用线性要素图形综合的渐进式方法,来保证岛群外围边界,从而保证了岛群的总轮廓和延伸方向不变。

| Abstract: | It is important to keep invariant relation of the density of distribution,the contrast of density,global contour and the global direction of extension of chains of islands during the auto-synthesizing process.In the paper the reduction of the chains of islands is gained via the determining of the border lines of the chains of islands.The progressive mode of the integrated drawing of linear elements is used to ensure the external border lines of the chains of islands and achieve the invariant of the global c... |
