helper_multiPoint

Create GeoJSON MultiPoint features from coordinate arrays to represent multiple point locations as a single geographic feature for spatial analysis and mapping applications.

Instructions

创建多点特征对象。

此功能根据坐标点数组创建多点特征，用于表示一组相关的点要素。

Args: coordinates: 多点坐标数组 - 类型: str (JSON 字符串格式的数组) - 格式: [[lng1, lat1], [lng2, lat2], ...] - 示例: '[[0, 0], [10, 10]]'

properties: 属性对象 - 类型: str (JSON 字符串) 或 None - 格式: 键值对对象 - 示例: '{"name": "point group"}' options: 可选参数配置 - 类型: str (JSON 字符串) 或 None - 可选字段: - bbox: 边界框数组 [minX, minY, maxX, maxY] - id: 特征的标识符 - 示例: '{"bbox": [-1, -1, 11, 11], "id": "multi_point1"}'

Returns: str: JSON 字符串格式的 GeoJSON MultiPoint Feature - 类型: GeoJSON Feature with MultiPoint geometry - 格式: {"type": "Feature", "geometry": {"type": "MultiPoint", "coordinates": [...]}, "properties": {...}} - 示例: '{"type": "Feature", "geometry": {"type": "MultiPoint", "coordinates": [[0, 0], [10, 10]]}, "properties": {"name": "point group"}}'

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 >>> coordinates = '[[0, 0], [10, 10]]' >>> properties = '{"name": "point group"}' >>> result = asyncio.run(multiPoint(coordinates, properties)) >>> print(result) '{"type": "Feature", "geometry": {"type": "MultiPoint", "coordinates": [[0, 0], [10, 10]]}, "properties": {"name": "point group"}}'

Notes: - 输入参数 coordinates、properties 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) - 多点特征包含多个独立的点 - 依赖于 Turf.js 库和 Node.js 环境
