Determine if a geographic coordinate ring follows clockwise direction to identify polygon boundaries versus interior holes in spatial data analysis.

Instructions

检查环是否为顺时针方向。

此功能检查给定的坐标环(多边形边界)是否为顺时针方向。

Args: ring: 坐标环数组 - 类型: str (JSON 字符串格式的数组) - 格式: [[x1, y1], [x2, y2], [x3, y3], ...] - 示例: '[[0, 0], [1, 0], [1, 1], [0, 1], [0, 0]]'

Returns: str: JSON 字符串格式的布尔结果 - 类型: 包含 value 的对象 - 格式: {"value": true 或 false} - 示例: '{"value": true}'

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 >>> ring = '[[0, 0], [1, 0], [1, 1], [0, 1], [0, 0]]' >>> result = asyncio.run(booleanClockwise(ring)) >>> print(result) '{"value": true}'

Notes: - 输入参数 ring 必须是有效的 JSON 字符串 - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 顺时针环在多边形中表示外部边界 - 逆时针环在多边形中表示内部孔洞 - 依赖于 Turf.js 库和 Node.js 环境
