misc_line_slice_along

Extract a specific segment from a GeoJSON line by specifying start and end distances from the beginning, enabling precise line segmentation for spatial analysis.

Instructions

沿线段长度截取指定距离范围的部分。

此功能根据起点距离和终点距离在线段上截取对应的部分，便于按长度分割线段。

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": [[7, 45], [9, 45], [14, 40], [14, 41]]}'

start_distance: 起点距离 - 类型: float - 描述: 从线段起点开始的截取起始距离 - 示例: 12.5 stop_distance: 终点距离 - 类型: float - 描述: 从线段起点开始的截取结束距离 - 示例: 25.0 options: 可选参数配置 - 类型: str (JSON 字符串) 或 None - 可选字段: - units: 距离单位 (默认: 'kilometers') - 有效值: 'miles', 'nauticalmiles', 'kilometers', 'meters', 'yards', 'feet', 'inches' - 示例: '{"units": "miles"}'

Returns: str: JSON 字符串格式的 GeoJSON LineString 特征 - 类型: GeoJSON Feature with LineString geometry - 格式: {"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": [[7, 45], [9, 45], [14, 40], [14, 41]]}' >>> options = '{"units": "miles"}' >>> result = asyncio.run(line_slice_along(line, 12.5, 25.0, options)) >>> print(result) '{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [[...]]}}'

Notes: - 输入参数 line 和 options 必须是有效的 JSON 字符串 - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 根据距离范围截取线段部分 - 依赖于 Turf.js 库和 Node.js 环境
