I want to label state names in QGIS but my original shapefile is built in county-level. If I simply label them with State, my map shows multiple labels in each state as my original file (one label for each county).

Is there any way to to that in QGIS?

  • The file I was using can be found here: cdmaps.polisci.ucla.edu; scrolling down the page and you shall find "district001.zip"

Use dissolve to merge the county polygons to state polygons and label those.

Vector | Geoprocessing tools | Dissolve

  • Yes I did that way but I had two bugs: it generated several unnecessary lines and dots in some states, which made it pretty ugly; when doing this, 2 counties were lost and I don't know why.

  • Does it matter? Does it impact the labeling result?
