PostGIS ST_Interacts和Join不工作

Question

我正在尝试连接多多边形（geom）和点（拾取），以便可以找到自治市镇中的拾取器数量。我正在使用下面的代码，但它超时并且不返回任何内容。我也尝试了ST_Contains什么都不返回。想法将不胜感激。谢谢。

SELECT z.borough, count(*) "Count"
FROM public.taxi_zones z
JOIN public.trips t 
    ON (z.geom && t.pickup)
WHERE ST_Intersects(t.pickup, z.geom)
GROUP BY z.borough

以下是数据示例。拾取数据类型为“几何体（点，4326）”，而geom数据类型为几何体（多边形，4326”。geom变量是一个非常长的字符串，因此我不能在不超过字符限制的情况下为它发布多个数据点。

Answer 1

我没有检查过你的几何图形，但是

SELECT z.borough,
       COUNT(t.*) AS "Count"
FROM   public.taxi_zones AS z
JOIN   public.trips AS t
  ON   ST_Intersects(z.geom, t.pickup)
GROUP BY
       z.borough
;

应该返回与每个taxi_zones.pickup相交的*的次数。

请注意，我在 COUNT 中指定了 t.*。

两个几何都必须有空间索引，并运行标准表维护来更新表统计数据。

没有必要添加bbox比较；< code>ST_Intersects包含完全相同的检查。
