| 摘 要： | 空间冲突检测是制图综合领域研究的难点问题之一。本文在分析了正八面体QTM(Quaternary Triangu-larM esh)数据模型的特点基础上,提出了基于QTM进行图形冲突检测的三级策略,并据此设计了一种有效的服务于图形冲突检测的QTM数据结构。

| Abstract: | The identification of map conflicts is one of the difficult problems in map generalization.In the paper we analyzes the characters of Octahedral Quaternary Triangular Mesh(QTM) for map generalization.Then we propose a strategy with three-level detection for graphic conflicts,and design a specific data structure serving for graphic conflict detections based on QTM. |
