Distances locations tree.query pts k 4
WebAfter we have built (initialized) the ball-tree, we run the nearest neighbor query with tree.query(src_points, k=k_neighbors), where the src_points are the building-coordinates (as radians) and the k-parameter is the number of neighbors we want to calculate (1 in our case as we are only interested in the closest neighbor). Finally, we just re ... WebSep 25, 2015 · Just a guess but maybe a k-d tree would help. I don't know if Python has an implementation. ... 30.18426696]) #how it works!

WebJul 19, 2024 · The problem is that the tutorial code provides coordinates in Longitude, Latitude format instead of the Latitude, Longitude format BallTree anticipates. So you're measuring distances between inverted points. If you swap the order of geom.x and geom.y in the coordinate parsing code you will get correct measurements.
