measurement_destination

Calculate destination coordinates by moving a specified distance and bearing from a starting point. Supports multiple distance units and returns GeoJSON Point features for geographic applications.

Instructions

从起点计算指定距离和方位角的目标点。

此功能从给定起点出发，沿着指定方位角移动指定距离，计算并返回目标点的位置坐标。

Args: origin: 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]}'

distance: 移动距离 - 类型: float - 描述: 从起点开始移动的距离值 - 示例: 50.0 bearing: 方位角 - 类型: float - 描述: 从北方向顺时针测量的角度 - 范围: -180 到 180 度 - 示例: 90.0 options: 可选参数配置 - 类型: str (JSON 字符串) 或 None - 可选字段: - units: 距离单位 (默认: 'kilometers') - 有效值: 'miles', 'nauticalmiles', 'kilometers', 'meters', 'yards', 'feet', 'inches' - properties: 传递给目标点的属性对象 - 示例: '{"units": "miles", "properties": {"name": "destination"}}'

Returns: str: JSON 字符串格式的 GeoJSON Point 特征 - 类型: GeoJSON Feature with Point geometry - 格式: {"type": "Feature", "geometry": {"type": "Point", "coordinates": [lng, lat]}} - 示例: '{"type": "Feature", "geometry": {"type": "Point", "coordinates": [-74.5, 39.5]}}'

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 >>> origin = '{"type": "Point", "coordinates": [-75.343, 39.984]}' >>> options = '{"units": "miles", "properties": {"name": "destination"}}' >>> result = asyncio.run(destination(origin, 50.0, 90.0, options)) >>> print(result) '{"type": "Feature", "geometry": {"type": "Point", "coordinates": [-74.5, 39.5]}}'

Notes: - 输入参数 origin 和 options 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
