使用AutoCAD软件来计算拨地工程的坐标成果较传统计算器人工计算是一个巨大的进步,即便如此,当遇到包含多个地块的拨地工程时,逐个地块完成计算并填写成果表格,工作量仍然很大,而且对于作业过程中局部小的调整还要进行大量重复工作,并且人工干涉多,容易出现纰漏。本文介绍利用自动搜索封闭地块多边形的图形算法,实现拨地工程地块坐标成果的自动化输出,从根本上解决了传统方法效率低、人工干涉多、易出错等问题。
使用AutoCAD軟件來計算撥地工程的坐標成果較傳統計算器人工計算是一箇巨大的進步,即便如此,噹遇到包含多箇地塊的撥地工程時,逐箇地塊完成計算併填寫成果錶格,工作量仍然很大,而且對于作業過程中跼部小的調整還要進行大量重複工作,併且人工榦涉多,容易齣現紕漏。本文介紹利用自動搜索封閉地塊多邊形的圖形算法,實現撥地工程地塊坐標成果的自動化輸齣,從根本上解決瞭傳統方法效率低、人工榦涉多、易齣錯等問題。

Although it is a huge progress to apply AutoCAD to calculate results of coordinates in land planning compared with tra- ditional calculation done by hand, the work load is still heavy in the land planning involving multi blocks which needs to calculate each block and fill out result tables respectively, and needs to repetitive work and artificial interfere if there is small partial ad- justment in project operation which may lead to careless mistake. This paper introduces a graphic algorithm of blind areas auto- matic search realizing automatic output of results of land coordinates, which solves problems including low efficiency, artificial in- terference and error proneness in traditional ways.
