random_randomLineString
Generate random line features within specified bounding boxes for geospatial testing and simulation. Create custom GeoJSON LineString collections with configurable vertex counts and spatial parameters.
Instructions
生成随机线特征集合。
此功能在指定边界框内生成指定数量的随机线,返回线特征集合。
Args: count: 生成线的数量 - 类型: int - 默认: 1 - 示例: 25
options: 可选参数配置
- 类型: str (JSON 字符串) 或 None
- 可选字段:
- bbox: 边界框数组 [minX, minY, maxX, maxY] (默认: [-180, -90, 180, 90])
- num_vertices: 每条线的顶点数量 (默认: 10)
- max_length: 顶点与前一个顶点的最大距离 (默认: 0.0001)
- max_rotation: 线段与前一线段的最大旋转角度 (默认: Math.PI/8)
- 示例: '{"bbox": [-180, -90, 180, 90], "num_vertices": 10}'Returns: str: JSON 字符串格式的 GeoJSON FeatureCollection - 类型: GeoJSON FeatureCollection with LineString features - 格式: {"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [...]}}, ...]} - 示例: '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[-74, 40], [-78, 42], [-82, 35]]}}, ...]}'
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 >>> result = asyncio.run(randomLineString(25)) >>> print(result) '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[-74, 40], [-78, 42], [-82, 35]]}}, ...]}'
Notes: - 输入参数 options 必须是有效的 JSON 字符串或 None - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 如果未指定边界框,默认在全球范围内生成随机线 - 依赖于 Turf.js 库和 Node.js 环境
