[postgis-users] compundcurve in polygons is supported in 1.4

[Mario Jurcevic]

Hi,
thanks very much I really need this datatype.
Will be possible to create polygons with multiple rings of compoundcurve?
A function like stcurvetoline with the interpolation of arcs will be
available for the polygons too?

Thanks

Mario

Actually I think I spoke too soon on this one.  Still apparently some issues
here.

Mario,

Sorry for no one getting back to you.  This is actually available in the
upcoming PostGIS 1.4 due out within the next 2 weeks. I had to test it to
verify myself.  So yes as of PostGIS 1.4 you can do this.

SELECT ST_GeomFromEWKT('CURVEPOLYGON(COMPOUNDCURVE(CIRCULARSTRING(0 0,2 0, 2
1, 2 3, 4 3),(4 3, 4 5, 1 4, 0 0)))');

I tried the same on PostGIS 1.3.6 and it doesn't work so guess you have to
wait for 1.4.

Hope that helps,
Regina

Hi,
Postgis community will develop compundcurve in polygons?
I will help with my work or with sponsoring a developper for code it.

Thanks
