SDO_GEOM.RELATE不正確的結果

我想確定兩個多邊形之間的關係。他們幾乎相等，但甲骨文決定的關係爲「TOUCH」SDO_GEOM.RELATE不正確的結果

我已經試過SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT驗證幾何形狀。他們都是有效的 – AnnaField

我發現它工作正常，極端小容忍（0.0000000005）。確定的關係是OVERLAPBDYINTERSECT。但我無法解釋它，我需要它與給定的公差0.0000005 – AnnaField

一起工作我不知道您使用的是哪個座標系，但我認爲它是笛卡爾系統的米。在這種情況下，座標'374119.43424706 5691944.80315028'將具有10納米（！）的精度。也許降低精度（請參閱https://spatialdbadvisor.com/oracle_spatial_tips_tricks/289/rounding-coordinates-or-ordinates-in-sdo_geometry），該精度仍然可以提供1毫米的精度，這應該遠高於您實際需要的精度。 –

什麼版本的Oracle？

我試着用Oracle 12.2測試用例。我在所有公差範圍內都得到了OVERLAPBDYINTERSECT，除了在0.5的時候我得到了包圍。

我沒有得到任何寬容的TOUCH。肯定TOUCH是不正確的。如果你確實得到了TOUCH，那麼這將是一個需要查看的bug - 除非你在舊的不再支持的版本上執行它...

我用12.1.0.2.0試過了，我也得到了TOUCH響應。絕對是一個錯誤。我會去看看。 –

我不是專家，TOUCHES的意思是「沒有常見的兩種幾何點相交兩個幾何的內部。」當你檢查圖片時，你會看到一個點的內部其他多邊形（用紅色圓圈標記）

多邊形有效。它內部有一個孔，這就是爲什麼它不是「關閉」（第一個和最後一個座標不同） – AnnaField

請參閱我的修改答案 –

TOUCH表示「邊界相交但內部不相交」給定內部多邊形明顯相交 – AnnaField

我認爲這是Oracle 12.1.0.2.0的一個bug，但我發現了一個解決辦法：

alter session set spatial_vector_acceleration=TRUE;

正確。我觀察到同樣的效果。 –

@AlbertGodfrind的問題是，我們無法將它設置爲系統參數 – AnnaField

爲什麼不能？我的意思是什麼阻止你設置這個參數系統範圍？顯然你需要DBA的權利。或者讓你的友好DBA去做。然後再次您不需要在系統範圍內設置它。只需在會話級別設置它，如圖所示。這不需要DBA的權利。 –
