With what level of accuracy are lat/lon pairs plotted? I've heard they're plotted to a zip level of accuracy, is that accurate? Do any of the custom maps, e.g., ArcGIS, Mapbox, show location more accurately?
Xiaoxin, your answer certainly isn't a solution and you shouldn't have marked it as such. Come on Microsoft....
My question, put another way:
How many decimal places in a given lat/lon coordinate pair are recognized by Power BI's 'map' visualization? For example, 6 decimal places is good enough to unambiguously recognize or discern an individual human, while 3 places is good enough for a street.
