Hi,

actually the question is: What do you expect for a result, Jukka? The picture by Michaël seems reasonable to me and I wonder how it should look for you.

cheers.,
Stefan

Hi Jukka,

As far as I remember (I did not find confirmation in Eric's documentation), the algorithm produces a single polygon.

In your case, there are several input polygons. If you densify their boundaries, you'll get something close to the original polygons, but with narrow corridors to rely them. I think this is a limitation of the algorithm rather than a bug. Here is what I get with a densification of 1m. Would be interesting to overcome this limitation though.

Hi,

I was playing with the Concave hull plugin and got usually good results. However, the attached data gives odd results even if I followed the hint to densify the geometries. Sending to the list if some developers happens to be interested in having a look.
