misc_line_segment
Decompose line and polygon geometries into individual line segments for detailed spatial analysis and coordinate processing.
Instructions
将几何图形分解为线段。
此功能将线或多边形几何图形分解为独立的线段，每个线段包含两个顶点坐标。
Args: geojson: GeoJSON 对象 - 类型: str (JSON 字符串格式的 GeoJSON) - 格式: 支持 LineString、MultiLineString、Polygon、MultiPolygon - 坐标系: WGS84 (经度在前，纬度在后) - 示例: '{"type": "Polygon", "coordinates": [[[-50, 5], [-40, -10], [-50, -10], [-40, 5], [-50, 5]]]}'
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 >>> polygon = '{"type": "Polygon", "coordinates": [[[-50, 5], [-40, -10], [-50, -10], [-40, 5], [-50, 5]]]}' >>> result = asyncio.run(line_segment(polygon)) >>> print(result) '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[-50, 5], [-40, -10]]}}, ...]}'
Notes: - 输入参数 geojson 必须是有效的 JSON 字符串 - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 返回所有几何图形的独立线段 - 依赖于 Turf.js 库和 Node.js 环境
