【摘要】:制图规范中要求不同界线实部相交,然而当前制图软件多未考虑界线相交处虚线的处理,而且国内外文献针对实部相交的研究较少,尚未形成完整的解决方案,基于此,本文根据单元循环配置法绘制地图线状符号的基本思想,首先拆分原始单元块,然后分解原始的数据图层,最后将新单元块和新图层对应配置,并据此设计了自动化处理方法。通过实际数据验证了算法的有效性和合理性,该方法顾及了不同等级、不同类别界线的差异,并通过自动化的处理方法提高了地图编辑的效率。
[Abstract]:The drawing specification requires the intersection of real parts of different boundaries. However, most of the current drawing software do not consider the processing of dotted lines at boundary intersections, and there are few researches on the intersection of real parts in the literature at home and abroad, which have not yet formed a complete solution, based on this, In this paper, according to the basic idea of drawing map line symbols by cell cycle collocation, the original unit blocks are split first, then the original data layers are decomposed. Finally, the new unit blocks and new layers are configured accordingly, and an automatic processing method is designed accordingly. The validity and rationality of the algorithm are verified by the actual data. The method takes into account the differences of different grades and different classification boundaries, and improves the efficiency of map editing by the automatic processing method.
