Mapping for single points on a map and filtering within a specific mile radius. I had a hard time finding what I needed exactly on the forums for the radius filter until I figured out a super easy way to do it. Here's how I do my mapping along with the associated filter for distance within a specific radius.

is it possible to calculate the geographical distance between to points a map which are based on longitude and latitude? For instance, I would like Tableau to show the distance to the nearest next point around the marked orange point.
BUFFER(MAKEPOINT([Dest Lat],[Dest Lng]),[Buffer Distance],"miles") The BUFFER calculation takes point spatial data and converts it into shapes with a radius in miles determined by the Buffer Distance parameter.
While exploring data in a map view, you might have questions about how that data relates to its surrounding geography, locations, or landmarks. To answer these types of questions, you can use the Radial tool to measure approximate distances in your map view.

First, I created the calculation (called Radius (in Miles)) to make sure the circles worked on your map: BUFFER( MAKEPOINT([Site Lat],[Site Long]) ,30, "miles") Next I created a parameter, which is essentially a variable, (called "Radius Distance") that allows the user to select how large the radius is
