If your location data does not fit into one of these roles, you may have to import custom geocoding to plot the data on a map. For example, you can assign the Airport geographic role to a field that contains International Air Transport Association (IATA) codes. You can assign geographic roles to your fields based on the type of geographic data they contain. Many of the roles are international, but some are limited to the US only. The following table describes the geographic roles available in Tableau. If you double-click each of these fields, Tableau adds them to the Columns and Rows shelves and creates a map view using the Tableau background map. These fields contain latitude and longitude values and are assigned the Latitude and Longitude geographic roles. To the measures area of the Data pane: Latitude (generated) When you assign a geographic role to a field, Tableau adds two fields In the Data pane, click the data type icon next to the field, select Geographic Role, and then select the geographic role you want to assign to the field.
