measurement_bearing

Calculate the geographic bearing between two points using GeoJSON coordinates to determine direction from north in degrees.

Instructions

计算两点之间的地理方位角。

该函数使用 Turf.js 库的 bearing 方法,计算从第一个点到第二个点的方位角。

Args: point1: 起点 GeoJSON Point 特征或几何图形 - 类型: str (JSON 字符串格式的 GeoJSON) - 格式: 必须符合 GeoJSON Point 规范 - 坐标系: WGS84 (经度在前,纬度在后) - 示例: '{"type": "Point", "coordinates": [-75.343, 39.984]}'

point2: 终点 GeoJSON Point 特征或几何图形 - 类型: str (JSON 字符串格式的 GeoJSON) - 格式: 必须符合 GeoJSON Point 规范 - 坐标系: WGS84 (经度在前,纬度在后) - 示例: '{"type": "Point", "coordinates": [-75.534, 39.123]}'

Returns: str: JSON 字符串格式的方位角结果对象 - 类型: 包含 value 和 units 的对象 - 格式: {"value": 方位角数值, "units": "degrees"} - 示例: '{"value": 45.5, "units": "degrees"}'

Raises: Exception: 当 JavaScript 执行失败、超时或输入数据格式错误时抛出异常

Example: >>> import asyncio >>> point1 = '{"type": "Point", "coordinates": [-75.343, 39.984]}' >>> point2 = '{"type": "Point", "coordinates": [-75.534, 39.123]}' >>> result = asyncio.run(bearing(point1, point2)) >>> print(result) '{"value": 45.5, "units": "degrees"}'

Notes: - 输入参数 point1 和 point2 必须是有效的 JSON 字符串 - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 方位角是从北方向顺时针测量的角度 - 依赖于 Turf.js 库和 Node.js 环境
