booleans_booleanPointInPolygon

Check if a geographic point lies within a polygon using GeoJSON data. Determine point-in-polygon relationships for spatial analysis and geographic containment testing.

Instructions

检查点是否在多边形内部。

此功能检查点是否位于多边形或多边形集合的内部。

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]}}'

polygon: 多边形特征 - 类型: str (JSON 字符串格式的 GeoJSON) - 格式: Feature with Polygon or MultiPolygon geometry - 示例: '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[0, 0], [2, 0], [2, 2], [0, 2], [0, 0]]]}}' options: 可选参数配置 - 类型: str (JSON 字符串) 或 None - 可选字段: - ignoreBoundary: 是否忽略边界 (默认: false) - 示例: '{"ignoreBoundary": 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]}}' >>> polygon = '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[0, 0], [2, 0], [2, 2], [0, 2], [0, 0]]]}}' >>> result = asyncio.run(booleanPointInPolygon(point, polygon)) >>> print(result) '{"value": true}'

Notes: - 输入参数 point 和 polygon 必须是有效的 JSON 字符串 - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 使用射线法算法判断点是否在多边形内部 - 边界上的点默认被视为内部 - 依赖于 Turf.js 库和 Node.js 环境
