I'm facing the problem that I want to calculate flight distances of Red Deer. I have a Layer with point Locations of animals; One attribute is the timestamp. I have another layer with point locations for humans who were trying to disturb the deer.
The problem is, I can't just calculate the distance between the points, because if the animal and the human are moving, the results will be wrong: if the animal moves away from the human, their paths will appear like they crossed although they both were not there at the same time.
So long story short:
I want to calculate the distances between human and animal simultaneously. What I want QGIS to do is to select all locations with the same/matching timestamp and calculate their distance.
