grid_triangleGrid

Generate triangular mesh grids within specified bounding boxes for spatial analysis and surface modeling applications in geographic data processing.

Instructions

在边界框内生成三角形网格。

此功能在指定的边界框内创建三角形网格，用于空间分析和表面建模。

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: 三角形每条边的长度 - 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: 传递给所有三角形的属性对象 - mask: 用于裁剪网格的多边形特征 - 示例: '{"units": "miles", "properties": {"type": "triangle"}}'

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": "triangle"}}, ...]}'

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(triangleGrid(bbox, 50.0, '{"units": "miles"}')) >>> print(result) '{"type": "FeatureCollection", "features": [{"type": "Feature", "geometry": {"type": "Polygon", "coordinates": [...]}, "properties": {"type": "triangle"}}, ...]}'

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) - 三角形网格提供灵活的空间划分，常用于表面建模 - 依赖于 Turf.js 库和 Node.js 环境
