misc_line_split
Split GeoJSON line segments into multiple parts using splitter geometries to divide spatial data for analysis and processing.
Instructions
用分割器将线段分割为多段。
此功能使用分割器几何图形将线段分割为多个部分，返回分割后的线段集合。
Args: line: 线 GeoJSON 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 LineString 规范 - 坐标系: WGS84 (经度在前，纬度在后) - 示例: '{"type": "LineString", "coordinates": [[120, -25], [145, -25]]}'
Returns: str: JSON 字符串格式的线特征集合 - 类型: GeoJSON FeatureCollection with LineString features - 格式: {"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [...]}}, ...]}
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 >>> line = '{"type": "LineString", "coordinates": [[120, -25], [145, -25]]}' >>> splitter = '{"type": "LineString", "coordinates": [[130, -15], [130, -35]]}' >>> result = asyncio.run(line_split(line, splitter)) >>> print(result) '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[120, -25], [130, -25]]}}, {"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[130, -25], [145, -25]]}}]}'
Notes: - 输入参数 line 和 splitter 必须是有效的 JSON 字符串 - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 使用分割器将线段分割为多个部分 - 依赖于 Turf.js 库和 Node.js 环境
