Smart way to detect too far away point from a row of points?
try arcgis.
build two new attributes in arcgis with their X and Y coordinate,then calculate the distance between the points you want
I'm working on a python script whose goal is to detect if a point is out of a row of points (gps statement from an agricultural machine). 
Input data are shapefile and I use Geopandas library for all geotreatments.
My first idea was to make a buffer around the 2 points around considered point. After that, I watch if my point is in the buffer. But results aren't good.
So I ask myself if there is a mathematical smart method, maybe with Scikit lib... Somebody is able to help me?
