measurement_bboxPolygon
Convert bounding box coordinates to GeoJSON polygon features for spatial analysis and visualization. This tool transforms rectangular bounding boxes into polygon geometry for use in mapping applications and geospatial 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]'
options: 可选参数配置
- 类型: str (JSON 字符串) 或 None
- 可选字段:
- properties: 传递给多边形的属性对象
- id: 传递给多边形的 ID
- 示例: '{"properties": {"name": "bounding box"}, "id": "bbox1"}'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
