摘要
本文研究探索了对已有1:10000地形图存量数据进行实体化改造,进而生产地理实体数据的方法,通过数据语义映射、模板化、自动化抽取、辅助编辑等过程,建立从地形图数据到地理实体数据的一整套可行的工艺方法。
Compared with the basic surveying and mapping data,geographic entities have the characteristics of quantifiable,statisticable and analyzable.In practical application,they can link all kinds of thematic information and are more widely used.This paper puts forward a method of quantitative transformation of geographic entity based on 1:10000 topographic map.Through the definition of data source,creation of entity template,establishment of data extraction scheme,geographic entity editing and other functions,the geographic entity data covering all areas and all elements is established.It lays a foundation for the preliminary research and experiment of the new basic surveying and mapping work.
