helper_feature
Create GeoJSON features by combining geometric shapes with attribute data for geographic data representation and spatial analysis.
Instructions
创建单个地理特征对象。
此功能将几何图形和属性信息组合成一个完整的地理特征,用于表示具体的地理要素。
Args: geometry: 几何图形对象 - 类型: str (JSON 字符串格式的 GeoJSON 几何图形) - 格式: 任何有效的 GeoJSON 几何图形 - 示例: '{"type": "Point", "coordinates": [-75.343, 39.984]}'
Returns: str: JSON 字符串格式的 GeoJSON Feature - 类型: GeoJSON Feature - 格式: {"type": "Feature", "geometry": {...}, "properties": {...}} - 示例: '{"type": "Feature", "geometry": {"type": "Point", "coordinates": [-75.343, 39.984]}, "properties": {"name": "Location A"}}'
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 >>> geometry = '{"type": "Point", "coordinates": [-75.343, 39.984]}' >>> properties = '{"name": "Location A"}' >>> result = asyncio.run(feature(geometry, properties)) >>> print(result) '{"type": "Feature", "geometry": {"type": "Point", "coordinates": [-75.343, 39.984]}, "properties": {"name": "Location A"}}'
Notes: - 输入参数 geometry、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) - 特征是 GeoJSON 中的基本数据单元,包含几何信息和属性 - 依赖于 Turf.js 库和 Node.js 环境
