摘　　要：【目的】以丰县1:4500航空影像为基础,利用IGS数字化测图模块绘制1:1000线划图。【方法】在数据预处理阶段,建立Geodatabase,并对图层数据进行分层处理。根据丰县某地区基础地理数据特点,利用ArcCatalog将数据库分为房屋、植被、水系、注记、道路等5个要素集,设计各要素集的子类型和属性域,根据要素类之间的拓扑关系设计了拓扑规则。【结果】在建库阶段,依据设计方案完成不同类型数据库构成要素的导入、构建,最后对地理要素进行符号化处理,完成了该地区数据库的构建。【结论】该数据库通过对数据的整合和完善,实现了丰县某地区不同类型数据的有效组织与管理。[Purposes]Based on the 1:4500 aerial image of Fengxian County,this paper uses IGS digital mapping module to draw 1:1000 line drawing.[Methods]In the data preprocessing stage,the Geodatabase is established and the layer data is layered.According to the characteristics of basic geographic data in Fengxian County,ArcCatalog is used to divide the database into five feature sets:house,vegetation,water system,annotation,and road.The subtypes and attribute fields of each feature set are designed,and the topological rules are designed according to the topological relationship between the feature classes.[Findings]In the database construction stage,the import and construction of different types of database elements were completed according to the design scheme.Finally,the geographic elements were symbolized and the database of the survey area was completed.[Conclusions]The results show that Through the integration and improvement of data,the database realizes the effective organization and management of different types of data in a certain area of Fengxian County.
