misc_line_chunk
Split line geometries into equal-length segments for spatial analysis and processing. Divide GeoJSON LineString or MultiLineString features into specified length segments using customizable distance units.
Instructions
将线分割为指定长度的线段。
此功能将线或多线几何图形分割为多个指定长度的线段，便于分段处理和分析。
Args: geojson: GeoJSON 对象 - 类型: str (JSON 字符串格式的 GeoJSON) - 格式: 必须符合 GeoJSON FeatureCollection, Geometry 或 Feature 规范，包含 LineString 或 MultiLineString - 坐标系: WGS84 (经度在前，纬度在后) - 示例: '{"type": "LineString", "coordinates": [[-95, 40], [-93, 45], [-85, 50]]}'
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": [[-95, 40], [-93, 45], [-85, 50]]}' >>> options = '{"units": "miles"}' >>> result = asyncio.run(line_chunk(line, 15.0, options)) >>> print(result) '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "LineString", "coordinates": [...]}}, ...]}'
Notes: - 输入参数 geojson 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) - 如果线长度小于分段长度，则返回原始线 - 依赖于 Turf.js 库和 Node.js 环境
