Hi,
That's because has not been implemented by default in postgis : you have to run the script which simon gave you at the end of his article. This wil create the necessary functions http://www.spatialdbadvisor.com/file_download/55/PostGIS_Parallel.sql Hugues. -----Message d'origine----- De : postgis-users-boun...@postgis.refractions.net [mailto:postgis-users-boun...@postgis.refractions.net] De la part de Pedro Costa Envoyé : mercredi 9 mai 2012 12:28 À : PostGIS Users Discussion Objet : Re: [postgis-users] st_offsetcurve Hi Simon, I had already seen its function. Congratulations. But it returns me the following error: ERROR: function st_parallel(geometry, integer, integer, integer) does not exist LINE 1: select (ST_Parallel(the_geom, 3, 0, 0)) as test ^ HINT: No function matches the given name and argument types. You might need to add explicit type casts. when i do this: select (ST_Parallel(the_geom, 3, 0, 0)) as test from tests do you know the problem? PS: I´m already install the function by your file Em 09-05-2012 11:22, Simon Greener escreveu: > You could try my ST_Parallel function that works with all geometry > based versions of PostGIS. > > http://www.spatialdbadvisor.com/postgis_tips_tricks/205/st_parallel-for-postgis > > > > NOTE: Projected based math only. > > regards > S > On Wed, 09 May 2012 20:15:41 +1000, Pedro Costa > <pedrocostaa...@sapo.pt> wrote: > >> Em 09-05-2012 10:46, Francois Hugues escreveu: >>> If i'm not wrong, this function really dos not exists in postgis >>> 1.5.3 and is avalaible since 2.0. >> >> Thanks. >> Anybody know a way of transform a polygon buffer in lines? >> >> >> _______________________________________________ >> postgis-users mailing list >> postgis-users@postgis.refractions.net >> http://postgis.refractions.net/mailman/listinfo/postgis-users >> > > _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users _______________________________________________ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users
