Unable to Create Maps Using Designated Market Areas


Published: 26 Apr 2013

Issue

Unable to use Designated Market Area (DMA) data to create map boundaries.

Environment

Tableau Desktop

 

Resolution

Option 1: Tableau Desktop 10.0

As long as you have a table showing DMA by zip code or county, you can assign the DMA field to be geographic based on the underlying geographic role (Zip or County.) Set the level of detail on the map to use DMA and the correct boundaries will display on the map.

Option 2: Tableau Desktop 9.3 and earlier versions

Use Custom Geocoding to plot the desired data on a map.

Cause

Designated Market Area is not a built-in geographic role. The ability to create custom territories was added in Tableau Desktop 10.0. 

Additional Information

DMAs are a trademarked television viewership boundary produced by Nielsen. The boundaries are made up based on zip codes or counties.
