SQL Server STIntersects 返回错误结果

Question

问题

我正在使用 Azure SQL 数据库来存储具有地理数据类型的表。在其中一张表中，我有多边形和多重多边形类型的地理。我已经使用几何图形的 wkt 然后

geography::STGeomFromText(?, 4326))

从 pandas DataFrame 插入了数据。我已经验证我可以查询我的数据并在 python 中正确绘制它。

但是，我现在尝试从一个点创建一个缓冲区，并找到该缓冲区与表中的几何图形之间的交集：

BEGIN
    DECLARE @location GEOGRAPHY = GEOGRAPHY::Point(40.4168, -3.7038, 4326);
    DECLARE @buffer GEOGRAPHY = @location.STBuffer(500);

    SELECT column1, geom.STAsText() as geom
    FROM my_schema.my_table
    WHERE geom.STIntersects(@buffer) = 1;
END

结果始终为 1，即使对于距离原点非常远的几何图形也是如此。

我尝试过的事情

我尝试使用

MakeValid()

纠正一些几何形状，但结果没有改变。这种错误几何形状的一个例子是：

我感到很失落，我觉得我表格中的几何图形可能不正确，但如果您有任何见解，这确实会有帮助。

Answer 1

解决了！我的多边形方向不正确，因此每个距离计算都关闭了。正如此评论中所解释的，解决方案是在计算距离之前重新调整多边形的方向。
