misc_line_overlap
Calculate overlapping segments between two line geometries using GeoJSON input. Returns overlapping line features for spatial analysis.
Instructions
查找两条线的重叠部分。
此功能计算两条线几何图形之间的重叠线段，返回这些重叠部分的几何图形。
Args: line1: 第一条线 GeoJSON 特征或几何图形 - 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": "LineString", "coordinates": [[115, -35], [125, -30], [135, -30], [145, -35]]}'
line2: 第二条线 GeoJSON 特征或几何图形
- 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": "LineString", "coordinates": [[115, -25], [125, -30], [135, -30], [145, -25]]}'
options: 可选参数配置
- 类型: str (JSON 字符串) 或 None
- 可选字段:
- tolerance: 容差距离
- 示例: '{"tolerance": 0.01}'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 >>> line1 = '{"type": "LineString", "coordinates": [[115, -35], [125, -30], [135, -30], [145, -35]]}' >>> line2 = '{"type": "LineString", "coordinates": [[115, -25], [125, -30], [135, -30], [145, -25]]}' >>> result = asyncio.run(line_overlap(line1, line2)) >>> print(result) '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[125, -30], [135, -30]]}}]}'
Notes: - 输入参数 line1 和 line2 必须是有效的 JSON 字符串 - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 返回两条线之间的所有重叠线段 - 依赖于 Turf.js 库和 Node.js 环境
