摘　　要：立足于“以三维地籍为核心的土地立体化管理模式”的需要,以SuperMap平台作为三维宗地图件输出的基础平台,结合三维地籍要素,文章提出了以超图布局控件作为图件承载,基于坐标映射的方式,设计了三维宗地图件属性的数据结构,综合建立了三维宗地图件。文章提出的建立三维宗地图件方法,能够为土地立体化管理中图件输出与制作提供技术借鉴。Based on the need of “ three-dimensional land management mode with three-dimensional cadastral as the core, ” the SuperMap platform is used as the basic platform for the output of three-dimensional parcel map pieces. Combined with the three-dimensional cadastral elements, the hypergraph layout control is proposed as the map. Based on the coordinate mapping method, the attribute structure of the three-dimensional parcel map piece data is designed, and the three-dimensional parcel map piece is comprehensively established. The method of establishing three-dimensional parcel maps proposed in this paper can provide technical reference for map output and production in three-dimensional land management.
