measurement_bboxPolygon
Convert bounding box coordinates into GeoJSON polygon features for spatial analysis and visualization. Transform rectangular bounds into polygon geometry for mapping operations.
Instructions
将边界框转换为多边形特征。
此功能将边界框坐标转换为完整的多边形几何图形，便于进行多边形操作和可视化。
Args: bbox: 边界框数组 - 类型: str (JSON 字符串格式的数组) - 格式: [minX, minY, maxX, maxY] - 示例: '[-82, 35, -74, 42]'
Returns: str: JSON 字符串格式的 GeoJSON Polygon 特征 - 类型: GeoJSON Feature with Polygon geometry - 格式: {"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [...]}} - 示例: '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[-82, 35], [-74, 35], [-74, 42], [-82, 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 >>> bbox = '[-82, 35, -74, 42]' >>> options = '{"properties": {"name": "bounding box"}}' >>> result = asyncio.run(bboxPolygon(bbox, options)) >>> print(result) '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[-82, 35], [-74, 35], [-74, 42], [-82, 42], [-82, 35]]]}}'
Notes: - 输入参数 bbox 和 options 必须是有效的 JSON 字符串 - 边界框格式为 [minX, minY, maxX, maxY] - 坐标顺序为 [经度, 纬度] (WGS84 坐标系) - 依赖于 Turf.js 库和 Node.js 环境
