[Qgis-user] voronoi / thiessen in sextante

[Agustin Diez-Castillo]

Hi,
Sextante provides two ways for drawing voronoi polygons. One called Voronoi
where I missed the buffer option provided by qgis elsewhere and the other
called Thiessen polygons thru SAGA. Results are far of being the same, as
one could expect, see the pic [1]. I have no problem with the first result
(pink) but I've found the saga one (magenta) more troublesome because some
of the original points are left out.

Should I report this like a bug?


The points set:
x,y,z,num1,num2
"1048.245","1784.277","-28.657","75041","104941"
"1047.880","1784.268","-28.675","75042","104941"
"1048.150","1784.249","-28.696","75043","104941"
"1047.575","1784.415","-28.659","75044","104941"
"1047.509","1784.269","-28.672","75045","104941"
"1048.050","1784.396","-28.685","75046","104941"
"1048.078","1784.211","-28.708","75047","104941"
"1048.667","1784.203","-28.736","75048","104941"
"1048.668","1784.411","-28.721","75049","104941"
"1048.688","1784.264","-28.705","75072","104941"
"1048.676","1783.978","-28.771","75073","104941"
"1048.701","1783.698","-28.777","75074","104941"
"1048.765","1783.411","-28.754","75075","104941"
"1048.824","1783.103","-28.681","75076","104941"
"1048.844","1782.931","-28.603","75077","104941"

All the above in Qgismaster 1db8347, running in mac 10.7.5
