thank you for your answer. That article is certainly helpful, however I do not understand how to properly use this for my particular case.
Custom Geocoding seems like a good option if one either has:
- few points to map (in which case latitude and longitude can easily be looked for and input manually)
- a geocoding tool/service (in which latitudes and longitudes can be obtained automatically and volume is not an issue)
I don't have either. However, most of my Zip Codes are indeed recognized. For example, out of around 2000 European Zip Codes, only 275 are unknown.
Tableau manages to calculate the latitude and longitude of most of them.
This leaves me to wonder if any of the following is possible
- Is there a way I can somehow export the geolocation data Tableau already calculated so I can then manipulate the few unknowns externally and then resolve the issue with custom geocoding?
- Can I get my hands on any sort of file that includes the "recognizable" Zip Codes (and NUTS if available) by Tableau. This way I can process my source data to match the closest/most appropriate recognizable values.
Thanks again, I appreciate your help.
