Multilinestring

A collection of zero or more linestrings. A multilinestring has no dimension. The boundary of a multilinestring is a multipoint object containing the start and end points of all the linestrings.

The following are examples of multilinestrings:

Examples

The following example uses the GEOMETRY type to create a table, use copy to load a multilinestring to the table, and then queries the table to view the multilinestring:

=> CREATE TABLE multilinestring_geom (gid int, geom GEOMETRY(1000));
CREATE TABLE
=> COPY multilinestring_geom(gid, gx filler LONG VARCHAR, geom AS ST_GeomFromText(gx)) FROM stdin delimiter '|';
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.
>>1|MULTILINESTRING((1 5, 2 4, 5 3, 6 6),(3 5, 3 7))
>>\.
=> SELECT gid, ST_AsText(geom) FROM multilinestring_geom;
 gid |                     ST_AsText
-----+----------------------------------------------------
   1 | MULTILINESTRING ((1 5, 2 4, 5 3, 6 6), (3 5, 3 7))
(1 row)

The following example uses the GEOGRAPHY type to create a table, use copy to load a multilinestring to the table, and then queries the table to view the multilinestring:

=> CREATE TABLE multilinestring_geog (gid int, geog GEOGRAPHY(1000));
CREATE TABLE
=> COPY multilinestring_geog(gid, gx filler LONG VARCHAR, geog AS ST_GeographyFromText(gx)) FROM stdin delimiter '|';
Enter data to be copied followed by a newline.
End with a backslash and a period on a line by itself.

>>\.
=> SELECT gid, ST_AsText(geog) FROM multilinestring_geog;
 gid |                                  ST_AsText
