Description (last modified by jbronn)

In the C API of GEOS, GEOSLineMerge returns a new geometry that is the result of having merged contiguous line strings in a geometry collection or multi-line string geometry.

Example:

>>> geomcoll = fromstr('MULTILINESTRING((1 1, 3 3), (3 3, 4 2))')
>>> print geomcoll.line_merge()
LINESTRING(1 1, 3 3, 4 2)

Now in the gis-1.1 mercurial repo, see ​http://geodjango.org/hg/gis-1.1/rev/87b34dce202d.

It is now a merged property that is only available on LineString and MultiLineString instances.
