摘　　要：现有的地图成图系统对最新版的地图分幅国家标准的支持不够充分,不能依据测区范围分幅,容易生成无效图幅,后期人工编辑工作量大。基于AutoCAD进行二次开发受制于AutoCAD,有断供风险。基于Qt、GEOS、PROJ、GDAL、libdxfrw等开源软件,本文使用C++设计实现了一个4层架构、多线程的地图自动分幅软件。它全面支持国家基本比例尺地图分幅标准,可以基于测区边界指定地图分幅范围来进行经纬度分幅和矩形分幅。在图廓整饰中,支持读取DWG/DXF格式的分幅接合表,附加数字正射影像参照和批量图廓整饰,运行速度快。该软件扩展性强,容易跨平台,对于在地图分幅上摆脱对AutoCAD的依赖有积极意义。The existing mapping systems of map does not fully support the latest national standards for map subdivision,and cannot perform subdivision based on survey range,so they often generate invalid map sheets,which makes the later manual editing workload is heavy.The secondary development based on AutoCAD is strictly restricted by Auto-CAD and there is a risk of outage.Based on Qt,GEOS,PROJ,GDAL,libdxfrw and other open source softwares,this paper designs and implements an automatic map subdivision software with a four-layer architecture and multi-thread capability,and jmplements it in C++.It fully supports the national standard of map subdivision,and can specify the subdividing range based on the survey boundary to perform latitude-longitude subdivision or rectangular subdivision.Map decoration supports reading subdivision map with DWG/DXF format,attaching digital orthophoto map as reference and fast batch map decoration.The software has strong scalability and can easily migrate to other operating systems.It has positive significance for map subdivision in avoiding the dependence on AutoCAD.
