I have a point feature class (one point) and a polygon feature class. I want to select the farthest polygon from the point using ATGIS pro or python/ArcPy. Do you know any idea how  to do this?

Thanks in advance

Oops - I was thinking of the Generate Near Table tool and instead referenced the Near tool. My apologies. https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/generate-near-table.htm If you generate a near table, you should get a ranking of which polygon feature is closest, second closest, etc. The highest rank would be the farthest from the input point. Give that a try.

You could use the Near tool https://pro.arcgis.com/en/pro-app/latest/tool-reference/analysis/near.htm to find the polygon with the greatest distance from your input point(s).

When I use Near Tool as a result it added $ field to my Point layer returning only one polygon : the nearest polygon not the farthest.

How could I calculate the farthest distance from a point location to a polygon edge? I have a water intake point and a protection zone polygon and would like to draw a circle around both that touches the farthest edge of the polygon.
