How did I not notice that Tableau Prep can't do spatial calculations before? Are they not in because they can't be "seen" in Prep? Why do I need them? Trying to do #IronQuest and get ready for Data + Maps Tableau User Group. I wanted to dynamically calculate the difference between the #F1 GP tracks to see optimal "next race" routing. Since Tableau (Desktop) can only do spatial calcs on a row level, I wanted to calculate distances between each and then PIVOT them so I can get a max/min. I can get the distances in Desktop but then I can't pivot calculated fields. This seems like it should be easier?!!? Sarah Bartlett Dennis Kao Tore Levinsen

If you have latitude and longitude coordinates, you can mimic the distance calculation using Haversine distance: https://www.thedataschool.co.uk/asha-daniels/finding-the-closest-distance-in-tableau-prep/

They gotta leave Alteryx with something it can do that Prep can't! :-P

When it comes to dealing spatial files, everything is easier with GIS... 😅
