Hey ho everybody We at sogis are looking for a way to convert arcs (curves) to lines without producing slivers and overlaps of adjacent geometries sharing the same arc. It is very important for us to find a postgis solution as postgis is the "working horse" in all our automatic data transformation processes. We looked at all available postgis functions and could not find a solution.
Attachments: - arcs.png: The geometries as stored in the postgresql table: lower left: two adjacent Polygon's / upper right: one Multipolygon with two adjacent parts in it. - stroked.png: The output when using ST_CurveToLine (The same when forcing right hand rule before calling ST_CurveToLine) Thanks for your thoughts - Maybe will see some of you at FOSSGIS in Passau, will give a presentation there... Cheers Oliver
