grid_hexGrid
Generate hexagonal grid patterns within specified geographic boundaries for spatial analysis and visualization. Create uniform spatial coverage using customizable cell sizes and units for geographic data processing.
Instructions
在边界框内生成六边形网格。
此功能在指定的边界框内创建六边形网格，用于空间分析和可视化。
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]'
Returns: str: JSON 字符串格式的 GeoJSON FeatureCollection - 类型: GeoJSON FeatureCollection with Polygon features - 格式: {"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [...]}, "properties": {...}}, ...]} - 示例: '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [...]}, "properties": {"type": "hexagon"}}, ...]}'
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(hexGrid(bbox, 50.0, '{"units": "miles"}')) >>> print(result) '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [...]}, "properties": {...}}, ...]}'
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) - 六边形网格提供均匀的空间覆盖，常用于地理分析 - 依赖于 Turf.js 库和 Node.js 环境
