摘　　要：为满足信息化社会对基础测绘的多样化需求,新型基础测绘应运而生。地理实体数据库建设作为新型基础测绘体系建设的重要一环[1],地理实体数据生产方法是当下建设新型基础测绘体系需要攻克的重点问题。本文从数据转换、语义构建和质量检查3个方面提出存量DLG转换基础地理实体的技术路线,并选取广州市琶洲区域进行方法实践。通过实践,针对存量DLG转换基础地理实体过程中的痛难点问题展开思考与讨论,对基础地理实体的生产方法研究和应用具有一定的参考意义。In order to meet the diversified information needs of society,the new fundamental surveying and mapping comes into being.The construction of geo-entity database is an important part of the construction of the new fundamental surveying and mapping system,and the production methods of geo-entity is the key problem to be solved.In this study,the technical route of converting stock DLG into fundamental geo-entity is proposed from three aspects:data conversion,semantic construction and quality check.Pazhou area of Guangzhou is selected for practice.Through practice,this paper explores and discusses the painful and difficult points in the process of converting,which has a certain significance for reference in the research and application of production methods of fundamental geo-entity.
