摘　　要：基础地理实体是其他地理实体和相关信息的定位框架和承载基础,新型基础测绘体系首次将地名实体纳入基础地理实体分类,将地理对象几何抽象模型与属性信息相关联,实现对地理对象地名信息的全面表达。本文收集整理萧山区最新现势性的电子地图数据库和兴趣点数据库,作为居民地、境界、交通、水系、机场、房产小区、大楼大厦、宾馆酒店、公园、风景名胜等地理对象地名信息提取的数据来源,利用地理实体抽象建模和存量数据实体化转换等技术构建地名实体,通过萧山区数字高程模型进行地名实体高程赋值,获取萧山区三维地名实体数据,为萧山区数字赋能社会治理工作提供支撑。Fundamental geo-entity is the positioning framework and bearing foundation of other geo-entity and related information.The new fundamental surveying and mapping system for the first time includes the geo-name entity into the classification of fundamental geo-entity,associates the geometric abstract model of geographic objects with attribute information,and realizes the comprehensive expression of the geo-name information of geographic objects.This paper collects and sorts out the latest electronic map database and point of interest database of Xiaoshan District,as the data source of the extraction of the geo-name information of geographic objects such as residential land,territory,transportation,water system,airport,housing estate,buildings,hotels,parks and scenic spots.The geo-entity is constructed by using the geo-entity abstract modeling and the entitative transformation of stock data.The geo-name entity elevation is assigned through the digital elevation model of Xiaoshan District,and the 3D geo-name entity data of Xiaoshan District is obtained,providing support for the special work of digital enabling social governance in Xiaoshan District.
