Thanks all for your replies.
I''l try to do some post-processing on the linestring as you Paul suggested.
Best regards

Hey,
if you want to do such basic sewing (same point for beginning/end),
it should be easyer to sew by hand.
If you do real line merge, (some shared part of lines are fusioned),
it is more difficult has you want your data to be interpolated (what should
happen if 2 shared segments have different d
LineMerge is implemented via the GEOS library which, unlike PostGIS,
only understands 3 dimensions max. So the 4th is sacrificed in the
process. There's no good / easy way to retain it. you could write a
post-process routine that took every output vertex and compared it to
the input geometry to try
Hi everybody,
I am trying to merge two linestring like in the following example:
select st_astext(st_linemerge(st_collect(ST_GeomFromEWKT('LINESTRING(5 5 5
5, 10 10 10 10)'),ST_GeomFromEWKT('LINESTRING(10 10 10 10 , 15 15 15
15)';
but the output is
"LINESTRING Z (5 5 5,10 10 10,15 15 15)"
