I guess you refer to the new -a and -s flags. These are not based on any
references. The idea for these new flags came from studying v.voronoi and
its outputs. These flags (particularly -s) are still somewhat experimental
because v.voronoi itself is numerically a bit unstable, sometimes creating
artefacts when input points/vertices are very close to each other. The
reference for the basic voronoi algorithm is in the manual. The -a and -s
flags are an example what else you can do with that algorithm.

[GRASS-dev] references for v.voronoi

[Anna Petrášová]

Hi,

we were just reviewing materials for class where we use v.voronoi, and
it has some fairly new functionality Markus added, which is not quite
covered in references. It would be great if anyone could suggest some
relevant articles for the algorithm or applications? I would be happy
to add them there.

Thank you,

Anna

Re: [GRASS-dev] [release planning] 7.4.0

[Markus Neteler]

Hi,

I'd like to make progress on the 7.4.0 release. Please  (all) check
the list of open bugs concerning the future 7.4.0 release:

https://trac.osgeo.org/grass/query?status=new=assigned=reopened=7.4.0=type=priority

I would also like to make progress on the Addons to be moved:
https://trac.osgeo.org/grass/wiki/Grass7Planning#Addoncandidatetobemovedtotrunk

Candidates:
G7A:r.geomorphon
G7A:r.object.geometry - +/- equivalent to v.to.db, but for raster
objects: very useful for many other modules (notably OBIA)
G7A:r.vect.stats - very simple, but nice functionality to have in core
G7A:v.centerpoint - basic GIS functionality
G7A:v.clip - very easy to use and expected GIS functionality without
hassle of complicated commmands :-)
G7A:v.profile - expected GIS functionality

thanks,
Markus
