[Qgis-user] How to edit repetitive data in QGIS

[Raymond Nijssen]

Hi Charlotte,

You can use the "dissolve" tool for merging features that have value(s) 
in common. In this case the field "name" contains that value.

Go:
Vector >> Geoprocessing tools >> Dissolve...
Remove the check mark at "Dissolve all (do not use field)"
Add the field "name" to unique ID fields list
Run

This worked for me. Only drawback is that all roads without a name were 
merged together. If you mind that, you can select and remove them before 
running the dissolve algorithm.

Good luck,
Raymond
