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

[Karl-Magnus Jönsson]

Hi!
Instead of editing the lines or attributes with all that work you can do this in the styling. In the labels tab of the layer properties there are rendering options. There is a checkbox for merging connected lines to avoid duplicate labels. Hope this works.

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
