面向任务地图综合中要素的语义性权重判定

Semantic Weights of Features in Task-Driven Map Generalization

摘要: 在综合过程中,不仅要考虑要素细节的几何性权重,还要考虑不同要素类的语义性权重,即要素类在地图空间中表示的详细度由该要素类和用户、用户任务的相关度决定,从而最终根据地理实体语义相似性量化地图综合中的地理实体权重。

Abstract: How to categorize spatial entities based on the user's task and how to get the semantic weight based on the semantic similarities among spatial entities of different categories are preseated.
