booleans_booleanPointOnLine

Check if a geographic point lies on a line segment or path. Use this tool to verify point-line spatial relationships in geospatial data analysis.

Instructions

检查点是否在线上。

此功能检查点是否位于线段或多线的路径上。

Args: point: 点特征 - 类型: str (JSON 字符串格式的 GeoJSON) - 格式: Feature with Point geometry - 示例: '{"type": "Feature", "geometry": {"type": "Point", "coordinates": [1, 1]}}'

line: 线特征 - 类型: str (JSON 字符串格式的 GeoJSON) - 格式: Feature with LineString or MultiLineString geometry - 示例: '{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[0, 0], [2, 2]]}}' options: 可选参数配置 - 类型: str (JSON 字符串) 或 None - 可选字段: - ignoreEndVertices: 是否忽略端点 (默认: false) - 示例: '{"ignoreEndVertices": true}'

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 >>> point = '{"type": "Feature", "geometry": {"type": "Point", "coordinates": [1, 1]}}' >>> line = '{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[0, 0], [2, 2]]}}' >>> result = asyncio.run(booleanPointOnLine(point, line)) >>> print(result) '{"value": true}'

Notes: - 输入参数 point 和 line 必须是有效的 JSON 字符串 - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 使用点到线段距离算法判断点是否在线上 - 允许一定的数值容差 - 依赖于 Turf.js 库和 Node.js 环境
