Plot smoothed polygons

Hello all,
Iwant to plot polygons on a map but without the rough edges. Is there a way to smooth such edges?

Thanks in advance,

João Rocha

Something like the figure here ?

Something close to that…yes. I’ll look on this and let you know.
Thanks again.

Hi Esteban,
I’m using Delaunay Triangulation to plot some rain data and i’ve obtained a grid pretty close to what i need, though i can’t smooth the polygon edges yet. I’ve changed PS_LINE_CAP and PS_LINE_JOIN in the gmt.conf but it still doesn’t smooth the edges. Is there a some way to smooth these edges without using blockmean or blockmedian?
