Hi,
I had reasonably good results for something similar combining these
things in PostGIS:
- ST_Segmentize(geom, ST_Length(geom)/ST_NPoints(geom)) to generate
extra points on long straight runs of your lines;
- ST_DumpPoints to extract just the points;
- ST_VoronoiPolygons to generate Voronoi c
nothing exact here - any approximate interpolation about midway
plus/minus would be fine...

Hi Karsten,
Probably this GRASS GIS Addon can help:
https://grass.osgeo.org/grass7/manuals/addons/v.centerline.html
If I got your wish right...
Best,

Hi All,
a general geospatial question to all:
I am trying to find out if there is any existing geospatial algorithm (in
any open Open Source Geospatial software) that would allow to use a network
of lines as a start point and expand those in such a way that I can create
new area boundaries for e
