Thank you for your answer. After carefully studying your answer, I finally found the problem. The reason why the bridges in the map are not aligned is because the map uses the coordinate system of Web Mercator, which looks different. Therefore, I used your suggestion to find an NPM class library“ Home | math.gl “,” math.gl - npm search It solved my problem. After converting the wgs84 coordinate system to Mercator plane coordinates, the bridge in the figure was aligned. Thank you very much for your answer, which pointed me in the direction
