[Qgis-user] length...

[Carson Farmer]

T,

To get the column length, you can use the export/add geometry function 
in fTools, which will create a copy of the dataset (as a shapefile) with 
an additional length field (or it will populated the length field if it 
already exists). From this you can use the compute basic statistics 
function to get the sum of the field...

Hopefully that's what you are looking for?
