I have two point datasets, one is landing location coordinates of commercial transporter aircraft (one coordinate pair per trip), the other is self-reported camp and hunt locations of the transporter clients/hunters (one or more coordinate pairs per trip). Both layers have a common attribute that links the trips to each other: Tnumber. I want to calc the distance between the landing locations and the hunter camp and hunt locations for those trips that share the same Tnumber. Help please.
