UK Filled Map Geocoding Pack for Tableau
If you enjoy creating maps of UK data in Tableau but would like to do them using the ‘Geographic Role’ menu to create either point or filled maps without the need to blend in a polygon data, this is the solution for you!
The following geocoding roles are available as both point and filled map mark types:
- CCGs (Clinical Commissioning Groups)
- LEPs (Local Enterprise Partnerships)
- NHS Area Teams
- Ceremonial Counties
- Middle Super Output Areas
- Parliamentary Constituencies
- Postcode Districts
- Postcode Sectors
- Local Authority Districts
- Lower Super Output Areas
- Postcode Areas
Installation & Use
Copy the ‘Local Data’ folder and its contents contained in the download to your ‘My Tableau Repository’ and restart Tableau Desktop. Then select the appropriate geocoding role by right clicking on a dimension, going to ‘Geographic role’ in the menu and selecting the role that corresponds to your dimension. Then double click on the dimension to draw a point mark type map, changing the mark type from ‘Automatic’ to the ‘Filled map’ creates a filled map. Alternatively use ‘Show Me’ to switch between the two map types.
While the ‘Local Data’ folder is in your Tableau Repository you will no longer have access to the default Tableau geocoding data. To restore back to default simply move the ‘Local Data’ folder out of your repository,rename it or delete it. Then restart Tableau Desktop.
If you wish to redistribute a workbook using this custom geocoding pack be sure to save the workbook as a packaged workbook (TWBX) or go to File -> Export Packaged Workbook… in the main menu.
I think anybody should be able to create their own custom filled maps. Alteryx makes it really easy to do just that, keep watching the blog for an upcoming post on how it’s done.
