grid_pointGrid
Generate regularly spaced point grids within specified geographic bounding boxes for spatial sampling and interpolation applications in geospatial analysis.
Instructions
在边界框内生成点网格。
此功能在指定的边界框内创建规则分布的点网格，用于空间采样和插值。
Args: bbox: 边界框数组 - 类型: str (JSON 字符串格式的数组) - 格式: [minX, minY, maxX, maxY] - 示例: '[-180, -90, 180, 90]'
cell_size: 网格单元大小
- 类型: float
- 描述: 点之间的间距
- 示例: 50.0
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'
- properties: 传递给所有点的属性对象
- mask: 用于裁剪网格的多边形特征
- 示例: '{"units": "miles", "properties": {"type": "grid_point"}}'Returns: str: JSON 字符串格式的 GeoJSON FeatureCollection - 类型: GeoJSON FeatureCollection with Point features - 格式: {"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "Point", "coordinates": [lng, lat]}, "properties": {...}}, ...]} - 示例: '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "Point", "coordinates": [-75.343, 39.984]}, "properties": {"type": "grid_point"}}, ...]}'
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 >>> bbox = '[-180, -90, 180, 90]' >>> result = asyncio.run(pointGrid(bbox, 50.0, '{"units": "miles"}')) >>> print(result) '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "Point", "coordinates": [-75.343, 39.984]}, "properties": {"type": "grid_point"}}, ...]}'
Notes: - 输入参数 bbox 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) - 点网格提供规则的空间采样点，常用于插值和统计 - 依赖于 Turf.js 库和 Node.js 环境
