Can community provide any solution what can be done forward.. Any extension where we can show current location tracking.. In tableau we are able to plot co-ordinates but how do we track live location or show it in map?
@Diksha Joshi Unfortunately Tableau doesn't give us feedback fore marks we've not defined-- those not on the screen. In other words, it won't let us put the pin down anywhere and get the lat/long in return.
That said, if your goal is to have a blue dot on the left and you want the zoomed-in map to on the right to follow along, there are a few options.
You can have Tableau show all cities, but leave them invisible. The city list can be found at city.tds and there will be A LOT of them-- so many it may make your machine slow to a crawl.
Hint: when testing, test with one state first.
That said, any populated area will be clickable and will return a lat/long, which you can use on the right.
Another option would be to cast an invisible net over the USA using two data scaffolds-- one with largest and smallest latitude, the other with largest and smallest longitude. I don't recommend this option because you'll have a LOT of points and a LOT of wasted space that a user will never click on. Additionally, the curvature of the earth means northern areas are more densely packed with intersections than southern.
A third option is a hybrid: Use the cities method but then (once the Lat/Long is returned*) create an invisible "radial flower" around the center point. You can you sin/cos to establish the specific lat/long.
