Was there ever any actual Spaceballs merchandise? a = np.sin (delta_phi / 2)**2 + np.cos (phi1) * np.cos (phi2) * np.sin (delta_lambda / 2)**2. res = r * (2 * np.arctan2 (np.sqrt (a), np.sqrt (1 — a))) return np.round (res, 2) Looks awful, I know — but just paste it in your code editor and don’t look at it (if you don’t want to). Haversine distance is the angular distance between two points on the surface of a sphere. Attention geek! Join Stack Overflow to learn, share knowledge, and build your career. x1 = df1.x_coord.values x2 = df2.x_coord.values y1 = df1.y_coord.values y2 = df2.y_coord.values We can then calculate the squared distances, d2 = np.square( x2 - x1 ) + np.square( y2 - y1 ) distances = np.sqrt( d2 ) The distances array is the required distance per row.
