# 如何向静态地图添加路线
在本主题中，您将了解如何使用 Amazon Location Service 向静态地图添加路线。您将完成使用 CalculateRoutes API 获取路线的步骤，然后使用 GeoJSON 以及点和线的自定义样式在静态地图上对其进行可视化。
## 添加路线的步骤
1. 从 `CalculateRoutes` API 获取路线。移除位于同一直线上的坐标以优化线串，防止查询字符串达到其极限。
1. 根据经过优化的坐标集，创建 GeoJSON 对象。
1. 取线串的第一个和最后一个点，然后添加点几何体来标记起点和终点位置。
1. 根据业务需求设置点和线串的样式，调整颜色、大小和标签等属性。
## 使用紧凑样式添加路线
在本示例中，您将向[如何向静态地图添加线条](how-to-add-line-static.md)中创建的线条添加一条包含起点和终点的路线。该路线将使用自定义样式进行定义，包括起点和终点的颜色、大小和标签。
