I am working with ArcGIS. In some areas of the map labels are shown twice or three times for the same name and the same area. I want to have one single label for each area.

  • Have you checked if duplicated labels are not caused by topology issues, e.g. overlapping polygons (same polygons on top of each other).

  • Also, have you checked that you don't have the same layer added in your Table of Contents more than once? It happens...

You should use the Maplex Label Engine (Customize --> Arcmap options --> Data View).

Then you can go to the Labels tab on your layer with labels, click Placement Properties. From there you can manage a number of different things, I can really recommend clicking around for a bit and see what you can do.

What you are looking for is in the Label density tab.

You can even decide how far away two labels has to be in order to be considered as duplicates.

  • Usually you can set-up it for each feature layer individual. See also the point Duplicate labels at Prioritizing and positioning labels

  • in addition you can detect duplicate and fix labelling directly in table to force just one label (exemple you create a label just for bigest entitie ...) Dec 8, 2015 at 11:33
