PostGIS 测试 - 多曲线（MULTICURVE）

1.建表

CREATE TABLE multicurvetable ( 
  id SERIAL PRIMARY KEY,
  name VARCHAR(128),
   geom GEOMETRY(MULTICURVE, 26910)
);

2.添加GIST索引

CREATE INDEX multicurvetable_gix ON multicurvetable USING GIST (geom); 

3.插入数据

INSERT INTO multicurvetable (name, geom) VALUES ('m1',
  ST_GeomFromText('MULTICURVE((0 0, 5 5),CIRCULARSTRING(4 0, 4 4, 8 4))', 26910)
);

4.QGIS中显示几何数据
