摘要
综合考虑不同来源空间数据的相关标准,对地理概念进行规范化;然后对不同数据标准建立相应的地理本体模型,同时建立不同本体模型中概念之间的映射和关联关系,并使用概念格算法来完成概念及其关系的有效管理;最后在陆海地图一体化显示中对地形图和海图数据融合的研究中进行了应用。
Considering comprehensively different spatial data sources of relevant standards, the geographic concepts were formalized, corresponding geographic ontology models were established based on these standards, and map-ping relationships between synonymous concepts in different models were built. It uses the concept lattice algorithm to manage concepts and their relationships. This research has been used in the study of data fusion of topographic map and chart map.
