Priority: medium | Milestone: PostGIS 2.0.0
Component: postgis | Version:
Resolution: | Keywords: homogenize collection ST_GeomFromKML
--------------------------+-------------------------------------------------
Comment (by colivier):
Synopsys become:
{{{
/*
** Given a generic geometry, return the "simplest" form.
**
** eg:
** LINESTRING() => LINESTRING()
**
** MULTILINESTRING(with a single line) => LINESTRING()
**
** GEOMETRYCOLLECTION(MULTILINESTRING()) => MULTILINESTRING()
**
** GEOMETRYCOLLECTION(MULTILINESTRING(), MULTILINESTRING(), POINT())
** => GEOMETRYCOLLECTION(MULTILINESTRING(), POINT())
*/
}}}
Commited in lwgeom as r5265 and r5266
Do you think is worth to be exposed as SQL function also ?
And if yes ST_Homogenize is a good name choice ?
