【摘要】：制圖規(guī)范中要求不同界線(xiàn)實(shí)部相交,然而當(dāng)前制圖軟件多未考慮界線(xiàn)相交處虛線(xiàn)的處理,而且國(guó)內(nèi)外文獻(xiàn)針對(duì)實(shí)部相交的研究較少,尚未形成完整的解決方案,基于此,本文根據(jù)單元循環(huán)配置法繪制地圖線(xiàn)狀符號(hào)的基本思想,首先拆分原始單元塊,然后分解原始的數(shù)據(jù)圖層,最后將新單元塊和新圖層對(duì)應(yīng)配置,并據(jù)此設(shè)計(jì)了自動(dòng)化處理方法。通過(guò)實(shí)際數(shù)據(jù)驗(yàn)證了算法的有效性和合理性,該方法顧及了不同等級(jí)、不同類(lèi)別界線(xiàn)的差異,并通過(guò)自動(dòng)化的處理方法提高了地圖編輯的效率。
[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.
