SDO_GEOM.RELATE不正确的结果

我想确定两个多边形之间的关系。他们几乎相等，但甲骨文决定的关系为“TOUCH”SDO_GEOM.RELATE不正确的结果

我已经试过SDO_GEOM.VALIDATE_GEOMETRY_WITH_CONTEXT验证几何形状。他们都是有效的 – AnnaField

我发现它工作正常，极端小容忍（0.0000000005）。确定的关系是OVERLAPBDYINTERSECT。但我无法解释它，我需要它与给定的公差0.0000005 – AnnaField

一起工作我不知道您使用的是哪个坐标系，但我认为它是笛卡尔系统的米。在这种情况下，坐标'374119.43424706 5691944.80315028'将具有10纳米（！）的精度。也许降低精度（请参阅https://spatialdbadvisor.com/oracle_spatial_tips_tricks/289/rounding-coordinates-or-ordinates-in-sdo_geometry），该精度仍然可以提供1毫米的精度，这应该远高于您实际需要的精度。 –

什么版本的Oracle？

我试着用Oracle 12.2测试用例。我在所有公差范围内都得到了OVERLAPBDYINTERSECT，除了在0.5的时候我得到了包围。

我没有得到任何宽容的TOUCH。肯定TOUCH是不正确的。如果你确实得到了TOUCH，那么这将是一个需要查看的bug - 除非你在旧的不再支持的版本上执行它...

我用的是Oracle 12.1.0.2.0 - 64bit – AnnaField

我用12.1.0.2.0试过了，我也得到了TOUCH响应。绝对是一个错误。我会去看看。 –

我推荐使用JTS Topology Suite，这是一个开源的基于Java的几何工具。使用SDO_UTIL.TO_WKTGEOMETRY，您可以复制/结果粘贴到JTS：

我不是专家，TOUCHES的意思是“没有常见的两种几何点相交两个几何的内部。”当你检查图片时，你会看到一个点的内部其他多边形（用红色圆圈标记）

多边形有效。它内部有一个孔，这就是为什么它不是“关闭”（第一个和最后一个坐标不同） – AnnaField

请参阅我的修改答案 –

TOUCH表示“边界相交但内部不相交”给定内部多边形明显相交 – AnnaField

我认为这是Oracle 12.1.0.2.0的一个bug，但我发现了一个解决办法：

alter session set spatial_vector_acceleration=TRUE;

正确。我观察到同样的效果。 –

@AlbertGodfrind的问题是，我们无法将它设置为系统参数 – AnnaField

为什么不能？我的意思是什么阻止你设置这个参数系统范围？显然你需要DBA的权利。或者让你的友好DBA去做。然后再次您不需要在系统范围内设置它。只需在会话级别设置它，如图所示。这不需要DBA的权利。 –
