Java postgis如何将jts转为坐标

Question

我的 postgis 数据库中的坐标格式为 shape geometry :

"0102000000020000000000000000000000000000000000000000000000000049400000000000005440"

如何在 Java 中将其转换为坐标 (x,y)？

Answer 1

您可以使用 PostGIS 函数：

SELECT path[1] AS number,
       st_x(geom),
       st_y(geom)
FROM st_dumppoints(
        '0102000000020000000000000000000000000000000000000000000000000049400000000000005440'::geometry
     );

 number | st_x | st_y 
--------+------+------
      1 |    0 |    0
      2 |   50 |   80
(2 rows)
