helper_geometryCollection

Combine multiple geometry types into a single GeoJSON feature collection for handling complex spatial data scenarios with mixed geometric elements.

Instructions

创建几何图形集合特征。

此功能将多个不同类型的几何图形组合成一个几何集合特征，适用于包含多种几何类型的复杂场景。

Args: geometries: 几何图形数组 - 类型: str (JSON 字符串格式的数组) - 格式: 包含 GeoJSON 几何图形的数组 - 示例: '[{"type": "Point", "coordinates": [100, 0]}, {"type": "LineString", "coordinates": [[101, 0], [102, 1]]}]'

properties: 属性对象 - 类型: str (JSON 字符串) 或 None - 格式: 键值对对象 - 示例: '{"name": "mixed geometries"}' 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": [99, -1, 103, 2], "id": "geometry_collection"}'

Returns: str: JSON 字符串格式的 GeoJSON Feature with GeometryCollection - 类型: GeoJSON Feature with GeometryCollection geometry - 格式: {"type": "Feature", "geometry": {"type": "GeometryCollection", "geometries": [...]}, "properties": {...}} - 示例: '{"type": "Feature", "geometry": {"type": "GeometryCollection", "geometries": [{"type": "Point", "coordinates": [100, 0]}, ...]}, "properties": {"name": "mixed geometries"}}'

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 >>> geometries = '[{"type": "Point", "coordinates": [100, 0]}, {"type": "LineString", "coordinates": [[101, 0], [102, 1]]}]' >>> properties = '{"name": "mixed geometries"}' >>> result = asyncio.run(geometryCollection(geometries, properties)) >>> print(result) '{"type": "Feature", "geometry": {"type": "GeometryCollection", "geometries": [...]}, "properties": {"name": "mixed geometries"}}'

Notes: - 输入参数 geometries、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) - 几何集合可以包含不同类型的几何图形 - 依赖于 Turf.js 库和 Node.js 环境
