Feature request #16478

Updated by Alexander Bruy almost 6 years ago

I did not find a concave polygon tool that behaves as I (and I presume many others) expect: to me the parameter to choose is the max length of the segment, whereas the existing tools seem to allow the choice of the proportion of convex polygon covered.

I have tried:

* QGIS Concave Hull in Processing

* Concave hull (k-nearest-neighbors) from plugin Concave Hull (this

works differently, and has the useful option of creating multiple hulls

based on a field)

as well as:

* PostGIS ST_ConcaveHull
