摘　　要：为解决科学研究中矢量地图数据缺失、真实数据获取难度大等问题,本文提出一种基于公开、多源矢量数字地图数据模拟制作方法。首先,通过VISI0建模方法针对不同专题数据构建典型地物单元模板;其次,基于数据几何变换、语义筒化、模板局部镶嵌等原理,对矢量数字地图数据进行局部变换;最后,通过对数据编辑处理完成模拟数据制作。采用实际数据试验验证表明,试验结果科学合理,该方法可用于特殊区域专题数据模拟制作,能够为科学试验提供重要的数据支撑。In order to solve the problem of vector map data missing jand difficult acquisition of real data in scientific research , a method of vector digital map data simulation based on public and multi-source data is proposed in this paper. Firstly , a typical ground feature template for different thematic data is established using the VISIO modeling method. Secondly, the local transformation for vector digital map is performed based on principles such as geometric transformation, semantic simplification and template mosaic. Finally , the simulated data is completed by editing the data. The experimental results show that the method is scientific and reasonable, and it can be used to make thematic simulation data for specific regions and provide data support for scientific research.
