DLG与基础地理实体数据融合生产研究

Fusion Production of Digital Line Drawing and Basic Geographic Entity Data

提出一种数字线划图(DLG)与基础地理实体数据融合生产,实现DLG与实体数据融合生产、联动更新的方法。依托2023年度实景三维福建的地形级基础地理实体数据生产项目,以福建省南平市新市区为研究区域,设计数字线划图与基础地理实体数据融合生产研究过程,包括图元勾绘、属性赋值、实体构建和数据接边等街道工序。试验产品数据经内外业核检,均符合两者各自的数据技术要求,表明该融合方法可行,为以后的数字线划图与基础地理实体数据融合生产提供了一种可复制、可操作的方法。

With the rapid development of new basic surveying and mapping technology,digital line drawing(DLG)and basic geographic entity data closely linked,in accordance with the“on-demand production,on-demand components”of the production mode,through the reference of“unity”model,explore the digital line drawing and basic geographic entity data internal connection,study the fusion of both production technology.This paper relies on the terrain-level basic geographic entity data production in the 2023 digital 3D Fujian construction project,taking the new urban area of Nanping City,Fujian Province as an example,and expounds the production research process of digital line drawing and basic geographic entity data integration.After inspection,this research and experiment has achieved good results,laying a foundation for the future fusion production.
