基于转换集模型实现地理数据再利用

Geographic Data Reuse Based on the Transition Set Model

针对地理数据利用现状中存在的问题,通过对不同地理数据库数据存储、管理、制图方法的研究后,采用MapStore平台,阐述了转换集模型的原理,并提出了相应的数据制图改化原则与数据再利用的技术方案。通过该模型在云南省数据改化实践中的应用,证明该模型有效提高了地理数据的利用效率,加快了地图的生产速度,与传统的地图更新制图相比更具有优越性,对促进测绘地形图数据高效利用与共享有着重要意义。

In view of the existing problems in the current situation of geographic data utilization,after studying the data storage,management and mapping methods of different geographical databases,the MapStore platform was used to explain the principle of the transition set model.The corresponding principle of data mapping modification and the technical proposal of data reuse were provided.By the application of this model in the practice of data modification in Yunnan Province,it is proved that this model effectively improves the utilization efficiency of geographical data,accelerates the speed of maps production,and is superior to the traditional map update mapping.Therefore,it is a great significance for promoting the efficient utilization and sharing of topographic map surveying data.
