Hi I have over 100 data points which are located across a region and 120 station pairs.

I want to extract some of them which are located along a station pair.

Therefore, maybe the code will be needed related to..

1. Find the information of the path from one station to another station in coordinate system.
2. Extract some data points which are near the station pair path in assigned distance.

Could you please let me know whether it is possible or not and the solutions?
