I am studying bird movements and have tracked their locations, ie from flower 1 to flower 2 to flower 3 etc. Each point is mapped out. I am trying to work out the relative direction for each movement of the bird. in the picture below the angles are A1 and A2. so A1 is the relative direction of the bird travelling from N2 to N3 based on the original direction of N1 to N2. I have over 1000 movements which are copletely random with up to 50 flowers per map. is there a way to run the movements with the outcome relative angle?
At this point the bird movements are stored in a spreadsheet. I am unsure of how to incorporate them for this purpose.
