measurement_rhumbDestination
Calculate a destination point from a starting location by moving a specified distance along a constant bearing (rhumb line). Useful for navigation and geospatial applications requiring precise location projections.
Instructions
沿恒向线计算目标点。
该函数使用 Turf.js 库的 rhumbDestination 方法，从起点沿着指定恒向线方位角移动指定距离来计算目标点。
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: 恒向线方位角
- 类型: float
- 描述: 从北方向顺时针测量的恒向线角度
- 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���
- 示例: '{"units": "miles", "properties": {"name": "rhumb 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": "rhumb destination"}}' >>> result = asyncio.run(rhumbDestination(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) - 恒向线方位角是沿着恒向线（等角航线）的方位角 - 依赖于 Turf.js 库和 Node.js 环境
