transformation_transformRotate

Rotate GeoJSON objects around their centroid or specified pivot point using angle values to adjust spatial orientation for mapping and geographic analysis applications.

Instructions

旋转 GeoJSON 对象。

该函数使用 Turf.js 库的 transformRotate 方法,围绕质心或指定枢轴点旋转 GeoJSON 对象。

Args: geojson: GeoJSON 对象 - 类型: str (JSON 字符串格式的 GeoJSON) - 格式: 任何有效的 GeoJSON 对象 - 坐标系: WGS84 (经度在前,纬度在后) - 示例: '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[0,29],[3.5,29],[2.5,32],[0,29]]]}}'

angle: 旋转角度 - 类型: float - 描述: 旋转角度(十进制度数),顺时针为正 - 示例: 10.0 options: 可选参数配置 - 类型: str (JSON 字符串) 或 None - 可选字段: - pivot: 旋转枢轴点坐标 (默认: 'centroid') - mutate: 是否允许修改输入对象 (默认: false) - 示例: '{"pivot": [0, 25], "mutate": false}'

Returns: str: JSON 字符串格式的旋转后的 GeoJSON 对象 - 类型: 与输入相同的 GeoJSON 类型 - 格式: 与输入相同的格式 - 示例: '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[0.5,29.2],[3.8,29.1],[2.7,32.3],[0.5,29.2]]]}}'

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 >>> geojson = '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[0,29],[3.5,29],[2.5,32],[0,29]]]}}' >>> options = '{"pivot": [0, 25]}' >>> result = asyncio.run(transformRotate(geojson, 10.0, options)) >>> print(result) '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[0.5,29.2],[3.8,29.1],[2.7,32.3],[0.5,29.2]]]}}'

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) - 角度为十进制度数,顺时针为正 - 默认围绕几何图形的质心旋转 - 依赖于 Turf.js 库和 Node.js 环境
