By default, the geodesic distance is used for distance calculations. Even if you were to substitute it with the radius of a sphere, assuming the Earth is spherical, at 3437.7468 NM, you will not be near the real, accurate distance. What is the make and model of this biplane? 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. edit Geodesic distance is the shortest distance between two coordinates, assuming the ellipsoidal shape of the Earth. The idea is to get a set of distances between all the points defined in a GeoDataFrame and the ones defined in another GeoDataFrame.. import geopandas as gpd import pandas as pd # random coordinates gdf_1 = gpd.GeoDataFrame(geometry=gpd.points_from_xy([0, 0, 0], [0, 90, 120])) gdf_2 = … Between adjacent elements?
