摘要
运用了面积比结合形状因子对多边形进行度量,改进了常见的单纯依靠形状因子的办法,通过试验验证了其可行性。
Annotations of polygon features are difficult in map annotations, mainly because methods for setting annotation texts are decided by different geometric characteristics of polygon features. The formation of polygon is measured by using area and formation factors, and the common method is improved.
