I have a shapefile of the rail network which I have converted to a CSV with LAT/LLONG data and the sequence for each plotted point (to use the line graph to draw a line between points). I would like calculate miles between two points and have tableau follow the rail line. Does Tableau have any type capability to project shortest routing? Or is there a calculation I could do to produce this?
I feel i could probably create a calculated field to calculate the distance between each LAT/LONG point manually through a route, but we're talking about 100s of points per route.
The following two KB articles may be able to provide some insight:
Hope this helps!
