Richard, I'm curious why you want to do this?
The answer is I think NO, but someone correct me if I am wrong. I think the tolerance argument of ST_Simplify is the max distance allowed between any 2 closest points of the original and simplified. Though that's a bit vague to me. Also I would recommend using ST_SimplifyPreserveTopology if you are running 1.3.3 with Geos 3+ over ST_Simplify. I suppose if you insist on min number of points, you could play around with a combination of ST_LineMerge and ST_Line_SubString and maybe even throw in a low number for ST_Simplify As described here http://postgis.refractions.net/documentation/manual-svn/ST_Line_Substrin g.html Hope that helps, Regina -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of richard -rw- weinberger Sent: Friday, November 21, 2008 8:35 PM To: [email protected] Subject: [postgis-users] simplify a linestring to n points hi list! does postgis provide a method to reduce/simplify a linestring to a specific number of points? i'm aware of st_simplify() but i have to set an lower limit. thanks, //richard _______________________________________________ postgis-users mailing list [email protected] http://postgis.refractions.net/mailman/listinfo/postgis-users ----------------------------------------- The substance of this message, including any attachments, may be confidential, legally privileged and/or exempt from disclosure pursuant to Massachusetts law.
