measurement_rhumbDistance

Calculate the rhumb line distance between two geographic points using constant bearing navigation. Accepts GeoJSON point coordinates and returns distance in specified units for navigation and mapping applications.

Instructions

计算两点之间的恒向线距离。

该函数使用 Turf.js 库的 rhumbDistance 方法,计算两个 GeoJSON 点特征之间的恒向线距离。

Args: point1: 第一个 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: 第二个 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]}' 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' - 示例: '{"units": "miles"}'

Returns: str: JSON 字符串格式的距离结果对象 - 类型: 包含 value 和 units 的对象 - 格式: {"value": 距离数值, "units": "距离单位"} - 示例: '{"value": 123.45, "units": "miles"}'

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]}' >>> options = '{"units": "miles"}' >>> result = asyncio.run(rhumbDistance(point1, point2, options)) >>> print(result) '123.45'

Notes: - 输入参数 point1、point2 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) - 计算的是两点之间的恒向线距离(等角航线距离) - 依赖于 Turf.js 库和 Node.js 环境
