This is a straight forward calculation but involves taking a square root which is slow compared to other operations. Instead use the square of the distance. Use the formula for the distance but just skip the square root. Maybe this isn't too slow in shapely. fostech stryker tech

Webb30 juni 2024 · To get this segment, take both endpoints of each segment of your polygon, and plug them into the equation for the line parallel & intersecting the ray mentioned earlier. That is y = ( (centerY-pointY)/ (centerX-pointX)) * (x - centerX) + centerY. WebbAn alternative method is to use nearest_points: from shapely.ops import nearest_points p2 = nearest_points (line, p) [0] print (p2) # POINT (5 7) which provides the same answer as the linear referencing technique does, but can determine the nearest pair of points from more complicated geometry inputs, like two polygons.
