[GRASS-dev] v.outlier

[helena]

this is an issue that may be related to the v.surf.bspline #96 bug.
When running v.outlier on 3D vector file with topology built but no  
DBF table
we get the following error:

v.outlier input=JR2007 output=JR2007_outlierfree  
outlier=JR2007_outliers thres_o=30
DBMI-DBF driver error:
Table 'Auxiliar_outlier_table' doesn't exist.
Error in db_execute_immediate()

ERROR: Impossible to write in the database

The output files are actually written but when trying to display them  
we get
GRASS 6.4.0RC5 (nc_spm_08):~/tgrassdata > d.vect JR2007_outlierfree  
siz=1 co=red
WARNING: Coor files of vector map <JR2007_outlierfree at helena> is larger
          than it should be (94411739 bytes excess)
WARNING: Unable to display areas, topology not available
Segmentation fault
GRASS 6.4.0RC5 (nc_spm_08):~/tgrassdata > d.vect JR2007_outliers siz=1  
co=red
WARNING: Coor files of vector map <JR2007_outliers at helena> is larger  
than
          it should be (839 bytes excess)
WARNING: Unable to display areas, topology not available

Looking at the manual it seems that the table is needed only for QGIS  
output where
the elevation is stored as category. So I am wondering whether this  
is  a bug
that needs to be fixed or whether the v.* lidar modules require points
with elevation stored in DBF (which is a problem for large datasets) -  
if that is
the case it should be probably mentioned in the man page.

These modules would be really useful if we could get them to work,

Helena
