http://trac.osgeo.org/grass/browser/grass-addons/grass7/vector/v.fixed.segmentpoints/v.fixed.segmentpoints.py#L102
102 # Read length
103 tmp = grass.read_command('v.to.db', map = voutline,
104 type = 'line',
105 layer = 1,
106 qlayer = 1,
107 option = 'length',
108 units = 'meters',
109 column = 'vlength',
110 flags = 'p')
111 vector_line_length = float(tmp.split('\n')[1].split('|')[1])
112
113 # Print vector line length
114 grass.message( "Vector line length in meter:" )
115 grass.message( vector_line_length )
116 grass.message( "----" )
it's just to get the length of the vector line for further calculations:
in normal and verbose mode:
----
Lese Objekte...
Vector line length in meter:
58858.3366368
----
as Moritz points out, it seems quiet mode suppresses the access to the
output of grass.read_command; his solution/workaround with GRASS_VERBOSE env
variable seems not to work here on my side.
