[GRASSLIST:1058] s.geom problems......

Grass users....

I have to create the most parsimonious
species range polygon out of sites where the species have beeen
observed/sensed and thought that s.geom w/ the delaunay option will do
it.
Whenever run the program with precision > 0 I get the following error:

-------------------------------------------------------------------------------------

GRASS:~ > s.geom input=WPHantaOct output=HAntaDEL2 precision=1
operation=delaunay
Reading sites map (WPHantaOct) ...
Found 38 sites ...
SoS: matrix[38,5] @ 8 Lia digits; lia_length (16); 0.008 Mb.

Removing duplicate vertices ...
siMarkDeletedDuplicates: 15 duplicate sites marked.

NOTE: long integer coordinates used for comparison. due to roundoff
      two sites may have identical coordinates, although in the
      input data they don't.
siRemoveDuplicates: 15 duplicate sites removed.

Plane Sweep: completed, cpu used 0.000000.

Lawson Flip: quInsert: SORRY, I'M FULL.
---------------------------------------------------------------------------------------

I checked the memory of the machine and it seems to have plenty of
space... plus I'm using only 38 sites!! Could someone tell me what I'm
doing wrong? It looks like it is doing the calculations but can't write
the output to the disk!

I will appreciate your help,
Best regards,
.
thanks.

If you're using the s.geom in GRASS 5.0, I believe it is majorly borked
somehow. The only "operation" that seems to work correctly is "sweep".
Also, it may not read a site_list properly.

Perhaps you could use a surface interpolation routine to achieve your
ends ??? I wish I could say it'll get fixed soon, but I don't expect it
to.
