【摘要】：大中比例尺地图上居民地表现为面状要素,其载负量可达总量的70%~80%,并且居民地名称与居民地要素表现为1∶n,使得面状居民地注记配置尤为复杂。本文参照标准图式规范,提出了一种面状居民地名称注记配置方法。首先,对居民地进行预处理,形成用于注记的注记体;其次,对注记体进行分类,不同类别的注记体分别生成相应的注记候选位置;然后,根据注记评价规则对候选位置进行评价;最后,依据冲突规则得到注记位置的最优解;以1∶5万地图数据进行了注记实验,取得了较好的效果。
[Abstract]:On the map of large and medium scale, the residents' land is shown as a plane element, and its negative content can reach 70% of the total amount, and the residents' name and the residents' elements are shown as 1: n, which makes the arrangement of the area residents' notes especially complicated. This paper refers to the standard schema specification. In this paper, a new method is proposed to configure the names of residents. Firstly, preprocessing is carried out to form the annotated entries for the residents; secondly, the annotated entries are classified, and the corresponding candidate locations are generated for the different types of annotators. Then, the candidate positions are evaluated according to the annotation evaluation rules; finally, the optimal solution of the annotated locations is obtained according to the conflict rules; and the annotation experiments with 1: 50,000 map data are carried out, and good results are obtained.
