Dear all,
Until today I hadn't appreciated that PostGIS now supports use of 4D
geometry storage (x, y, time, z). I have a NetCDF file that stores
data in a similar way, and would like to bring it into PostGIS instead
for use with my other data. In order to do this I need to understand
how to use
I resum this post (new offset in my life).
I try the select on that geometry using
"POSTGIS="2.0.3 r11128" GEOS="3.3.8-CAPI-1.7.8" PROJ="Rel. 4.8.0, 6 March
2012" GDAL="GDAL 1.10.0, released 2013/04/24" LIBXML="2.8.0"
LIBJSON="UNKNOWN" (core procs from "2.0.1 r9979" need upgrade) RASTER

Hi Stephen
How can you explain that the st_offsetcurve make offset according to line
direction.
For example
SELECT ST_OffsetCurve (geom, -20) as geom_off
FROM table
WHERE id_arc in (1690,1693)
give me the result that you can see in the attached image rendering in qgis
(One Direction on the left,
The direction is always considered from start point to end point. You need
to use these methods to determine everything else.

Hi Sandro,
thank you for your answer,
I'll upgrade my GEOS, but I work for a Public Administration and this
process is slow.
So I have Isolated the geometry wher St_OffsetCurve crash.
There are two type of geometries:
1) Geometry with repeated points. I can solve the problem using:
St_OffsetCurv
