Coverts list of point locations to a set of equally spaced points through linear interpolation.
equa_dist_points_angle(df, num_splits = 13)
| df | 2 column data frame with all points (x,y) |
|---|---|
| num_splits | integer number of points for the path to be represented in |
new_compression data.frame (num_splits x 2) of points along the path equally spaced
