在线状要素注记配置规则的基础上,分析了城市街道注记自动配置规则,研究了从图面注记到空间目标名称属性的自动转换方法。结合Arc/Info平台的特点,给出了城市街道注记离散化定位的自动推理策略和计算方法,在Arc/Info平台上编程实现了该算法。
According to principles of cartographic name placement on line objects, the name placement rules on city streets are deduced in this paper. And, a novel approach is presented to automatically convert the labels of the annotation layer into the name attributes of the associated spatial objects. The paper presents an automated reasoning strategy and mathematical algorithms on the discrete placement of street names. At last, these algorithms are realized on the Arc/Info platform, and a case study is given.
