Hi,
This morning I noticed very odd output from v.voronoi, specifically on "split"
between adjacent points was missing and the output messages contained the
following:
Number of nodes: 22
Number of primitives: 27
Number of points: 0
Number of lines: 0
Number of boundaries: 20
Number of centroids: 7
Number of areas: 6
Number of isles: 1
Number of duplicate centroids: 1
The resulting voronoi polygons are attached.
Here are some details on the vector:
Number of points: 127
type count min max
point 127 1 127
line 0 0 0
boundary 0 0 0
centroid 0 0 0
area 0 0 0
face 0 0 0
kernel 0 0 0
all 127 1 127
Here is the version information:
GRASS 6.5.svn (2010)
./configure --with-tcltk-includes=/usr/include/tcl8.4 --with-postgres --without-odbc --with-mysql --with-mysql-includes=/usr/include/mysql/ --with-freetype --with-freetype-includes=/usr/include/freetype2 --with-readline --with-cxx --enable-largefile --with-postgres-includes=/usr/local/pgsql/include/ --with-postgres-libs=/usr/local/pgsql/lib/ --with-sqlite --with-python --with-proj-share=/usr/local/share/proj/ --with-cairo
Revision: 38990
Date: 2009-09-05 10:01:13 -0700 (Sat, 05 Sep 2009)
Could it be that the bad output is caused by some fundamental problem with the
input point vector?
Cheers,
Dylan
