transformation_transformTranslate

Translate GeoJSON objects along a rhumb line by specifying distance and direction. Move geographic features to new positions while maintaining spatial relationships.

Instructions

平移 GeoJSON 对象。

该函数使用 Turf.js 库的 transformTranslate 方法,沿恒向线移动 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]]]}}'

distance: 移动距离 - 类型: float - 描述: 移动距离,负值表示相反方向 - 示例: 100.0 direction: 移动方向 - 类型: float - 描述: 移动方向(十进制度数),从北方向顺时针测量 - 示例: 35.0 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' - zTranslation: 垂直移动距离 (默认: 0) - mutate: 是否允许修改输入对象 (默认: false) - 示例: '{"units": "miles", "zTranslation": 10, "mutate": false}'

Returns: str: JSON 字符串格式的平移后的 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": [[[0.6,29.3],[4.1,29.3],[3.1,32.3],[0.6,29.3]]]}}'

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 = '{"units": "miles"}' >>> result = asyncio.run(transformTranslate(geojson, 100.0, 35.0, options)) >>> print(result) '{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [[[0.6,29.3],[4.1,29.3],[3.1,32.3],[0.6,29.3]]]}}'

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) - 方向从北方向顺时针测量 - 距离可以为负值,表示相反方向移动 - 依赖于 Turf.js 库和 Node.js 环境
